284 H. N. MOSBLEY. 



Under surface pale yellowish. Lengthy 3 cm. ; breadth, 5 mm. 

 Mouth at about the centre of the under surface. 



Bahia, Brazil. 



2. Geoplana Traversii, sp. n. — Body elongate, flat beneath, 

 slightly convex above, bluntly pointed posteriorly, more gradually 

 attenuated anteriorly ; broadest in the centre. Mouth central in 

 position. Generative aperture situate at little less than half the 

 distance between the mouth and posterior extremity. Ambu- 

 lacral line absent, the whole under surface acting as a sole. 



Eye-spots forming a single row of ten or so on the front of 

 the anterior extremity, and an elongate patch composed of two or 

 three rows on the lateral margin of the body, just behind the 

 interior extremity ; also present, sparsely scattered, on the lateral 

 margins of the body for its entire length. 



Body of a pale yellow on the lateral margins, with a broad 

 mesial stripe on the dorsal surface, extending for its entire length, 

 of a dark chocolate colour, and four narrow, ill-defined, and some- 

 what irregular similarly coloured stripes on either side of it, 

 extending to the lateral margins of the body. Under surface 

 pale yellow. 



Length of largest specimen contracted in spirits, 3 cm. ; extreme 

 breadth of same, 8 mm. ; length of pharynx of same, 3*5 mm. 



N.B. — The above description applies to two specimens received 

 at WeHington from Mr. Locke Travers, in spirits. 



Two other specimens, obtained from him at the same time, 

 also in spirit, agree with the above description in all respects, 

 excepting that they have, curiously enough, a pair of well- 

 defined, dark, longitudinal stripes, on the under surface of the 

 body. 



Further, two living specimens of a Geoplana were obtained 

 at Wellington by collectors from the ' Challenger,' which 

 were each 2' 5 cm. in length. They were of a fine rich 

 yellow colour along the sides, with a broad mesial longitudinal 

 stripe of very dark chocolate on the back, which was seen by 

 the aid of a lens to consist of reticularly arranged pigment, 

 denser along a narrow median line towards the head and at the 

 verges of the broad band. The under surfaces were pale yellow 

 with reticulations of pale brick-red pigment. These latter may 

 have been the young of G. Traversii, and the specimens with 

 striped soles varieties of the same. Or two further species may 

 be here represented. The egg capsules obtained seem to have 

 been certainly of a distinct species from G. Traversii, since the 

 embryos contained in them have a light mesial dorsal strij)e 

 bounded by dark stripes on either side. It is hoped that some 

 resident New Zealand naturalist may investigate the species of 

 Laud Planarians of the island.
