Il8 GARRETT: CATALOGUE OF CYPR^IDiE. 



Adult shells vary considerably in size, and some are 

 decorated with the peculiar letter-like markings which char- 

 acterise C. Arabica. The polygonal maculse are constant, 

 also the large diffuse spot on the left side of the aperture, 

 Young specimens exhibit four transverse bands. 



This species is quite distinct from C. Arabica, with which 

 it is sometimes confounded. 



The animal has a snuff-brown mantle, which is nearly 

 colorless on the margins, and furnished with small, subulate, 

 tentacular processes of a pale grey color. Upper surface of 

 the foot purple-black, delicately mottled with a lighter shade; 

 creeping disk pale grey. Muzzle and tentacles purple-black, 

 the latter with a basal white spot. 



43. C. rhinoceros, Souv. ? We found several more or less 

 perfect examples on sandy flats at the Viti and Samoa Islands. 

 The specific characters agree very closely with the descrip- 

 tion and figure of Souverbie's species, v/hich was obtained at 

 New Caledonia. 



44. C. scurra, Chem. Common at the Paumotus, and somewhat 

 rare at all the other groups. Living specimens occurred 

 under large blocks of dead coral on the outer reefs. 



The young shell is marked with four rather faint, light- 

 brown bands on a bluish-grey gi'ound. 



Animal olivaceous-brown, with a pale locomotive disk. 

 Mantle with small, rather remote, elongate, conical papillae. 

 Siphon with a terminal fringe. 



45. C. Stolida, L. This fine species seems to be somewhat 

 rare, only occurring to our notice at the Viti and Samoa 

 Islands, where we found several dead but very perfect shells 

 on sandy-mud flats. 



46. C. (Luponia) semiplota, Mighels. We obtained a few 

 examples of this species at the Sandwich Islands, where it is 

 peculiar.
