Palcemonetes varians (Leach) and vulgaris (Say). On its occurrence 
and development, see above, in the General Subject. 
Hippolyte, as first proposed by Leach (1813 or 1814) = Virbius (Stimp- 
son), but as nothing but additional synonymy and confusion can result, 
the author accepts the generic names as they now stand. The 
number and position of the teeth upon the rostrum and dorsal carina vary 
considerably : in H.fahricii (Kroyer), above from 3-5, beneath from 2-6 ; 
in H. macilenta (Kroyer), above from 9-15, beneath from 1-4 ; in H. 
phippsi (Kroyer), above from 6-10, beneath from 1-4 ; in H. polaris 
(Ross), above from 0-8, beneath from 2-5 ; in II. phippsi, 1 or 2 supra- 
orbital spines on each side ; in II. polaris the pterygostomal spine well 
developed, or rudimentary, or wholly absent. Eleven species from North 
America north of Cape Cod enumerated, II. gaimardi (M.-Edw.), securi- 
frons (Norm.), pusiola (Kroy.), polaris (Ross) figured. S. I. Smith, Tr.
