by a, Mr. Lewis, together with other species which are undoubtedly 
West- African forms. 
12. Leucozo^ia ocellata ( Gindin ). 
Sab. West Indies. 
The specimens obtained offer no differences from ordinary 
West-lndian examples. 
13. Latirtjs spadiceus (Reeve). 
A single young shell seems to belong to this species. 
L. concentricus , Reeve, L.brevicauda , Reeve, L. gracilis, Reeve, 
and the present species are very closely related. 
14. Mitra barbadensis ( Gmelin ). 
Sab. West Indies, Barbados, St. Vincent, &c. 
M. tessellata, Kiener, which Reeve named M.picta, is perfectly 
distinct from the present species, and well known as a South - 
African shell. Tryon not possessing or not having seen the 
species, at once concludes, from their general superficial resem- 
blance, that it must be the same as M. barbadensis. The sculpture 
of the two is quite different. _/LT. barbadensis is ornamented with 
raised spiral lines, whilst M. picta exhibits transverse punctured 
strife. The character of the outer lip also is quite different. 
15. Mitra (Pusia) ansulata, Sowerby.

Mitra microzonias, Reeve (non Lamarck), Con. Icon. figs. 185, 202;

Tryon, Man. Conch, iv. p. 183, pi. 54. figs. 568, 569. 
Sab. St. Thomas (Mus. Cuming ) ; “ West Indies, Morch, Krebs, 
and Swift,” fide Tryon. 
This species is said to occur in Polynesia, but the British 
Museum Collection affords no evidence in proof of this statement. 
The shell from Fernando Noronha belongs to that form of the 
species as figured by Reeve (fig. 185). 
This is usually considered the M. microzonias of Lamarck, but 
if it be compared with the figure of that sjiecies in the ‘ Ency- 
clopedic Methodique’ (pi. 374. fig. 8), it will be seen that it is 
a much more slender shell. The true M. microzonias has also 
been figured by Kiister (Con. -Cab. pi. 17. figs. 12, 13), and Reeve 
also correctly depicts it (Con. Icon. pi. xxx. fig. 242 on left) under 
the name of M. leucodesma. Sowerby in his description of
