NKHITINA. 35 



.V. Xoi'os- Caledonia*, Baird (figs. (57, 68), is a synonym. My 

 figure of X. stricta is unfortunately taken from Sowerby's Thesaurus* 

 and is certainly not typical, Baird's figure being exactly like N. 

 Nowe-Caledonice in all its features except being darker colored.

Genus NEKITINA, Lam. 1809. 

 Section NERITIXA (sensu stricto), Swainson. 1840. 



N. GAGATES, Lam. PL 10, figs. 77-79, 97, 98 ; PL 11, fig. 6. 



Striulate, polished, olivaceous or brownish black, with close black 

 zigzag lines; aperture bluish white. Diam. 18-26 mill. 



Mauritius, Seychelles, Isle of Bourbon. 



The synonyms are N. liturata, Recluz, N. Caffra, Gray, N. zigzag, 

 Morelet. Von Martens has vars. minor (fig. 78), and subplanispira 

 (fig. 79), the latter for depressed specimens. I think that N. ful- 

 f/vrata, Desh. (figs. 97, 98), from Isle of Bourbon, described from a 

 single specimen, is simply a light-colored example of this species. 



X. XATALENSIS, Reeve. PL 10, figs. 80, 81; PL 11, fig. 9. 



Striulate, somewhat shining, yellowish brown with oblique black 

 Btrigations, more or less decurrent or reticulately confluent; aper- 

 ture bluish white. Diam. 19-23 mill. 



Mozambique to Natal. 



It is A r . zebra, Krauss. N. Moquiniana, Recluz (fig. 9), is an un- 

 identified species from "Islands of the South Sea," which appears 

 to be closely related. 



X. VAKIEGATA, Lesson. PL 10, figs. 82-86; PL 12, figs. 23, 24. 



Somewhat shining, variegated with yellowish brown and black, 

 usually in an irregular net- work pattern, the meshes large or small, 

 sometimes the black reticulations form irregular broad bands, and 

 occasionally they cover the entire surface so as to make it nearly 

 unicolored ; aperture whitish or bluish white, the columella with a 

 tinge of orange-brown. Diam. 16-23 mill. 



East Indies, Polynesia.
