A thin, white marginal band is present and a broader, orange submar- ginal band may be prominent or absent. The branching of the dorsal vessels was ex- amined in four specimens with coloration typ- ical of T. In one individual, only the left lateral branch was pres- ent, but a secondary right branch was situated off the side of the right posterior branch. There are 17-18 coarse denudes on either side of the tooth. The prostate consists of approximately six elongate finger-shaped glands. Another specimen from Australia (CASIZ 071469) and the specimen from the Maldives illustrated by Yonow (1994), had faint blue lines on the para- podia, but lacked any trace of blue on the head or foot. A v-shaped black band is near the middle of each rhinophore and the rhinophores are tipped with orange. The anterior vessels are bi- furcate near their tips. 6B, C) contains a large pharyngeal 10 PROCEEDINGS OF THE CALIFORNIA ACADEMY OF SCIENCES Volume 49, No. Description of four new species of phanerobranch dorids (Mollusca: Nudibranchia) from the Indo-Pacific, with a redescription of Gymnodoris aurita (Gould, 1852). The inside of the para- podia is usually brownish with scattered tur- quoise blue pigment. They are bifurcate or slightly more highly branched. In all cases, there are both lateral and posterior vessels. These ducts join immediately anterior to the round, short stalked ampulla. Guinea (CASIZ 072919) examined had faint blue markings on the parapodia and head, but lacked any trace of blue on the foot. There is a narrow black band surrounding the head, near the level of the eyes. These vessels are thin compared to most other species. An apical transverse black band may also be present on the rhinophores. The edge of the parapodia is lined with a band of bright orange. Species of the hazelae Group of Plan-mantis (Amphibia: Ranidae) from the Philippines, with descriptions of two new species. This may be present as a series of red longitudinal lines or a distinct transverse band. bayeri appears first in the text and is, therefore, regarded as the senior synonym. Johnson and Boucher (1983) noted that the egg capsule size of T. On this basis, Thuridilla ratna is regarded as a ju- nior synonym of T. Both species were described in the same paper (Marcus, 1965), but T. The cutting margin bears 16-18 coarse denticles per side of the tooth. Near the posterior end of the mass a spherical receptaculum semi- nis joins the gland mass via a thin, moderately long duct. bayeri and two with color- ation characteristic of T. Carlson and Hoff (1978) also noted differences in the coloration of the inner surface of the parapodia in specimens from Guam. bayeri, the margin of the inner portion of the parapodia is white, fol- lowed by a red-orange band, an area of black, followed by a large area of steel blue. ratna, the submarginal red-orange band is usu- ally absent and the inside of the parapodia is brownish, with scattered white and blue mark- GOSLINER: THURID1LLA Figure 4. This pigment appears to be somewhat in- termediate between the two species. bayeri have blue pigment on the dorsal surface of the head between the rhinophores and additional blue on the anterior portion of the foot. Thuridilla GOSLINER: THURIDILLA ratna is considered uncommon in Western Aus- tralia (Wells and Bryce, 1993) and, together with Jensen's (1992) record from Thailand, rep- resents the only other record of this color form from the Indian Ocean. All three have paired lateral vessels from the pericardium and posterior vessels that originate from a common junction with the pericardium. No consistent differences in the relative proportions of the muscular buccal mass and pharyngeal pouch and the shape and size of the radular teeth could be determined in the present material, with one exception. splendens is slightly larger proportionately than the pouch of T. The fact that some specimens had faint blue markings on the parapodia and en- tirely lacked blue markings on the head and foot, suggests that they are intermediate in col- oration between that described for the two spe- cies. They may entirely lack branches or have a few secondary branches. There is no morphological dif- ference between specimens of different color patterns. ratna consisted of 26-27 teeth (8-9 in the ventral limb, 8-9 in the dorsal limb and 9 to more than 10 loose teeth in the ascus). 5) are triangular with the ser- rated portion longer than the basal one. — The reproductive morphology is complex and appears complicated, due to the diffuse distri- bution of the ovotestis, prostatic cells and al- GOSLINER: THURIDILLA Figure 2.

Distal reproductive organs of specimen with color typical of T. The female gonopore exits into the lateral ciliated groove, adjacent to the anus. The reproductive morphology was examined in three specimens with color- ation typical of T. — Thuridilla bayeri is similar in appearance and appears closely related to two other species, T. bayeri, blue spots along the parapodia and black spots along the parapodial margin. ratna, from Guam and Ma- laysia, have a prominent red submarginal band and some bluish pigment in the pericardial re- gion. ratna has been found from the western Indian Ocean. The con- figuration of the reproductive system, including the shape of the bursa copulatrix and penial papilla, is virtually identical in the specimens typical of T. No consistent difference in pattern could be discerned.

A new species of treefrog from the Serengeti National Park, Tanzania (Anura: Hyperoliidae: Hyperolius). In some specimens, the white or cream lines widen dis- tally and form a transverse band. Another animal depicted by Wells and Bryce (1993: fig.

The Acanthaceae of California and the peninsula of Baja California. The margin of the anterior end of the foot is red or orange. From the pos- terior end of the pericardium are two other blood vessels, that are joined basally. They connect via a pair of elongate hermaphroditic ducts.

Two black lines and an orange band are present at the base of the parapodia, as well.

Its presence is independent of the presence of red pigment. From its sides, are two lateral vessels which bifurcate terminally or remain undivided. — CASIZ 070285, one specimen, Manado, Sulawesi, Indonesia, 0.5 m depth, , Pauline Fiene-Severns. Immediately inside this band is a narrower black band.
