12. Leucozojsia ocellata {Gmelin). 

 Hah. West Indies. 



The specimens obtained offer no differences from ordinary 

 West-Indian examples. 



13. Latirtjs spadiceus (Heeve). 



A single young shell seems to beloug to this species. 

 L. concentricus, Eeeve, L. bred can da, Eeeve, i._y/'ftc-'///s, Keeve, 

 and the present species are very closely related.

Sab. West Indies, Barbados, St. Vincent, &c, 

 M. tessellata, Kiener, which Eeeve named M.jjicta, is perfectly 

 distinct from the present species, and well known as a South- 

 African shell. Tryou *, 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. barhadensis. The sculpture 

 of the two is quite different. M. barhadensis is ornamented with 

 raised spiral lines, whilst 3£. picta exhibits transverse punctured 

 stria'. The character of the outer lip also is quite different.

This species is said to occur in Polynesia, but the British 

 Museum Collection affords no evidence in proof of this statement. 



The shell from Pernando Noronha belongs to that form of the 

 species as figured by Eeeve (fig. 185). 



This is usually considered the M. inicrozonias of Lamarck, but 

 if it be compared with the figure of that species in the ' Eucy- 

 clopedie 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 Eeeve 

 also correctly depicts it (Con. Icon. pi. xxx. fig. 242 on left) under 

 the name of M. leucodesma. Sowerby in his description of
