332 CEYLON PEARL OYSTER REPORT. 



whitish-yellow ; jaws and teeth as in the genus Galvina. The median teeth of the 

 radula robust, with short point, and 5, sometimes 6, lateral denticles. This species 

 differs from the other members of the genus in having the anterior angles of the foot 

 produced, but otherwise it is a typical Galvina. All hitherto recorded Galvinse are 

 either Atlantic or Mediterranean, with the exception of G. crigua, which Bergh (15) 

 has recorded from the Pacific. This adds the Gulf of Manaar. 



Eolis, spp. ? 



There are two other small Eolids, representing two different species, in the 

 collection, both from the oyster cages hung over the ship's side in the Gulf of Manaar, 

 which are too small to identify. One of these, length 4 millims., is, perhaps, a Hervia. 

 It has the anterior angles of the foot produced, the tentacles long and slender, the 

 rhinophores small ; the papillse are crowded, long and slender, with acute white 

 cnidogenous tips and dark greenish-black contents. The body colour is a transparent 

 reddish-yellow. 



The other sjiecimen, length 4 millims., has the papillse in 5 distant transverse rows ; 

 the larger papilla? are ringed in a manner that recalls the genus Zatteria, described 

 by Sir C. Eliot (11, p. 62) from Zanzibar specimens. The rhinophores are moderately 

 large and rugose, the tentacles small and the anterior angles of the foot produced. 



Family: DOTONID^E. 

 Doto, sp. ? 



One specimen of a Doto, length 2 '5 millims., too small to identify, was obtained 

 from the above-mentioned oyster cages in the Gulf of Manaar. Externally it bears 

 a close resemblance to D. pinnatifida, Mont., the form, coloration, and black spots on 

 the papillar tubercles being in agreement with that species. 



Bergh (9, p. 795) has recorded a species of Doto (D. indica) from Mauritius, to 

 which it is possible that the specimen should be referred. 



Family : TETHYMELIBID^. 



Melibe fimbriata, Ald. and Hanc. 



There are three specimens of this species from separate localities on the West 

 Coast of Ceylon. One from off Negombo, one from Periya Paar, ( J fathoms, and one 

 from Chilaw Paar, 11 fathoms. As usual, they are in a very imperfect state, having 

 lost several of their dorsal papillae. 



Professor Herdman notes in his diary the colour of the living animal as follows : 

 " Pale amber brown, in front, with brownish papillse and white sjjots clear, 

 gelatinous." This species, as was first pointed out by Alder and Hancock (5), and 

 subsequently confirmed by Sir Charles Eliot (11), differs from the rest of the genus 

 in having no trace of labial or buccal armature. 



M. fimbriata is found throughout the Indian Ocean.
