ZOOLOGY OE FERNANDO NORONHA.

white, variegated with very dark brown or black. The single 
specimen, ivhich differs from the rest, is of a pinkish tint sparingly 
marked with rich brown. 
9. Oliya literata, Lamarck. 
Hab. West Indies, Gulf of Florida. 
Two beach-rolled shells are all that were obtained. They have 
the transverse lirse on the inner lip extending over nearly the 
entire length of the columella. 
10. Oliya (Oliyella) niyea ( Gmelin ). 
Hab. St. Vincent and other islands of the West Indies, 
Venezuela, and Brazil. 
The shell named by Mr. Watson * Oliva fulgida, Reeve, from 
Fernando Noronha, does not belong to that species, but is a 
prettily coloured example of O. nivea. O. fulgida differs from 
Gmelin’s species in the form of the columella and basal cauda. 
The columella of O. nivea is very peculiarly excavated, and this 
may be seen by looking as far within the aperture as possible. 
No such excavation occurs in O. fulgida, which also does not 
exhibit the numerous oblique folds or lirse on the columellar 
margin of the aperture which distinguish O. nivea. 
A second species is quoted with doubt by Watson from Fer- 
nando Noronha, namely O . pulchella, Duclos. The two fragments 
referred to this species seem to me to bear little resemblance to 
Du'clos’s figure ; but 1 have no hesitation in considering them 
specifically identical with tbe other specimen from the same spot 
which I refer to O. nivea. 
11. Leycozonia cingulifera {Lamarck). 
Hab. West Indies, Honduras, West Africa. 
L. rudis , Reeve, is I consider quite distinct from this species. 
With this exception I agree with Tryon in his synonymy, and 
would even suggest the propriety of maintaining L. leucozonalis , 
Lamk., as a variety of this species. 
The specimens from Fernando Noronha have stout rounded 
ribs, exhibit a distinct submedian white zone on the body-whorl, 
and have the aperture inclining to orange. 
Tryon questions the West- African habitat of this species, but 
I am inclined to think it correct, as in the British Museum there 
are three specimens from that locality presented some years ago
