There are two species of Nephropsis in the West Indian region, N. agassizii 
A. M. Edw., with two pairs of lateral spines on the rostrum, and N. aculeata 
Smith, with only one pair of rostral spines. V. agassizii was very inade- 
quately. described by A. Milne Edwards, and the type specimen, from the 
Strait of Florida, 1,500 metres, has never been returned to Cambridge. Soon 
after, the other species, N. aculeata, was described by Smith from specimens 
obtained off the south coast of New England, in 100 to 126 fathoms. Subse- 
quently Smith and other authors supposed that N. aculeata was identical with 
N. agassizii. The chief differences between the two species are the following. 
In N. agassizii the rostrum is armed with two or two and a half pairs? of 
lateral teeth; in V. aculeata there is only one pair of lateral rostral spines ; 
! Tdentified as P. agassizii by A. Milne Edwards, and so recorded by him in 
Bull. Mus. Comp. Zoöl., Vol. VIIT. p. 66, 1880. 
2 The third lateral spine may occur on either the right or the left side of the 
rostrum,
