490 MB. H. N. RTDLET ON THE 



This s^jecies belongs to the same group as T. gnUinar/o, Eeeve 

 (Con. Icon. fig. 5), and T. testudinarius, Adams & Keeve, and 

 some others. Although possibly not adult, the single shell at 

 hand is in excellent condition, and affords all the necessary 

 characters distinctive of the species. The last whorl has two 

 varices, namely the labrum and one on the opposite side. The 

 nuclear whorls are broken ofl"; but, judging from the top of the 

 first normal whorl, the apex would be comparatively small. The 

 uppermost of thelir£e on the columella is rather conspicuous, and, 

 together with the uppermost of those within tlie labrum, forms a 

 semicircular sinus above. 



18. Triton pileaeis, Lamarck. 



Hah. West Indies, Eed Sea, Ceylon, Philippine Islands, island 

 of Anna, &c. {Brit. Mus.). 



This, like some other species of Triton, occurs at the West 

 Indies and in the Indian and Pacific Oceans. 



19. Tkiton (Epideomus) testaceus, Morch. 

 Hah. West Indies {Morch). 



This species is very -like T. obscurus, Eeeve, but difters in 

 having more convex whorls, a granulated columellar callus, and a 

 narrower labral varix which is also hollowed out behind. 



20. Ctpe^a oineeea, Gmelin, var. 

 Hah. West Indies. 



With this species I unite C. clara of Graskoii:, with which the 

 specimens from Fernando Noronha agree. This variety is of a 

 longer and more cylindrical form than the type, has only traces 

 of the black dotting around the base, and no purplish stain 

 between the teeth. Sowerby's figure (Thes. Conch, pi. 307. f. 91*), 

 badly copied by Tryou (Man. Conch. vol. vii. pi. 1. f. 8), does not 

 represent the variety clara ; but a fair representation of it is given 

 by Sow^erby on pi. 316, figure 222. The colour, however, is not 

 pinkish, and no dotting occurs along the sides in the types de- 

 scribed by Gaskoin. 



21. Ctpe^a (Teivia) pediculus, Linne. 

 Hah. West Indies. 



One of the specimens from Fernando Noronha is remarkably 

 small, measuring only 7 millim. in length.
