opaque-white, and tipped with vermihon-red. The dusky- 

 grey siphon is dotted with diluted white, and the end is 

 fringed with short, blunt, pink tentacular processes. The 

 upper surface of the foot is delicately marbled wdth light 

 brown and ochre-yellow. Head tinged with cherry-red. 



20. C. (Luponia) errones, Lin. Common under dead coral 

 in both outer and inner reefs at the Viti Islands, but less 

 abundant at all the other western groups. Two examples 

 found at Kaukura, one of the Paumotu Islands, are of a 

 more robust shape than western examples. 



They vary considerably in the convexity of the dorsal 

 region, and about one in ten exhibits the large spot on the 

 back. They are frequently marked with three wide transverse 

 bands which are a little darker than the ground color, which 

 latter is somewhat variable. The young are bluish-grey> 

 frecked with olive yellow, and the apex black. 



21. C. (Luponia) esontropia, Duclos, A very rare species, 

 found washed up on the beaches at the Kingsmill, Cook's 

 and Paumotu Islands. 



22. C. (Luponia) felina, Gmel. This also seems to be a rare 

 species, and was obtained only at the Viti Islands, where we 

 found several specimens on sandy-mud between tide marks. 



23. C. fimbriata, Gmel. This small species, though diffused 

 nearly all over Polynesia, is not by any means common. 

 We obtained living examples beneath dead coral on the 

 outer reefs. The young exhibit four indistinct, pale yellowish- 

 brown bands. 



The animal is cherry-red, with a paler creeping disk, and 

 the cinereous siphon is anteriorly fringed. The. mantle is 

 ornamented with snnple, scattered, pale tentacular processes. 



24. C. (Luponia) fuscomaculata, Pease. A rather rare species 

 confined to Western Polynesia, where it represents the closely
