MR. H. N. RIDLEY ON THE 
This species belongs to the same group as T. gallinago , Reeve 
(Con. Icon. fig. 5), and 'T. testudinarius, Adams & Reeve, 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 off ; but, judging from the top of the 
first normal whorl, the apex would be comparatively small. The 
uppermost of thelirse on the columella is rather conspicuous, and, 
together with the uppermost of those within the labrum, forms a 
semicircular sinus above. 
18. Triton pilearis, Lamarck. 
Hab. West Indies, Red 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. Triton (Epidromus) testaceus, Morch. 
Sab. West Indies (Morch) . 
This species is very like T. obscurus , Reeve, but differs in 
having more convex whorls, a granulated columellar callus, and a 
narrower labral varix which is also hollowed out behind. 
20. CYPRiEA oinerea, Gmelin, var. 
Sab. West Indies. 
With this species I unite C. clara of Graskoin, with which the 
specimens from Eernando 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 Sowerby on pi. 316, figure 222. The colour, however, is not 
pinkish, and no dotting occurs along the sides in the types de- 
scribed by Graskoin. 
21. Cyprjsa (Trivia) pedicures, Linne. 
Sab. West Indies. 
One of the specimens from Fernando Noronha is remarkably 
small, measuring only 7 millim. in length.
