North Carolina to Labrador and Europe. In depth it extends from 
low water to 60 or 70 fathoms, and probably much deeper. 
HIPPOLYTE PUSIOLA Kroyer. (p. 395.) 
Monografisk Fremstlling Hippol., p. 319, Pl. 3, figs. 69-73, 1842. 
Vineyard Sound and northward to Greenland and Europe. 
VIRBIUS ZOSTERICOLA Smith, sp. nov. Plate III, fig. 11. (p. 369.) 
Female: Short and stout. Rostrum about as long as the carapax, 
and reaching nearly, or quite, to the tip of the antennal scale; the upper 
edge nearly straight and unarmed, except by two, or rarely three, teeth 
at the base; under edge with three (sometimes two or four) teeth on the 
anterior half. Carapax smooth and armed with a stout (supra-orbital) 
spine on each side at the base of the rostrum and above and a little 
behind the base of the ocular peduncle, a small (antennal) spine on the 
anterior margin beneath the ocular peduncle, and a stout (hepatic) spine 
behind the base of the antenna. Inner flagellum of the antennula ex- 
tending very slightly beyond the tip of the antennal scale; outer flagel- 
lum considerably shorter. Abdomen geniculated at the third segment; 
the posterior margin of the third segment prominent above, but not 
acute. 
The males differ from the females in being smaller, much more slen- 
der, and in having the rostrum narrower vertically. 
The color in life is very variable. Most frequently the entire animal 
is bright green, sometimes pale, or even translucent, tinged with green. 
Others were translucent, specked with reddish brown, and with a broad 
median band of dark brown extending the whole length of the body. 
Length of female, 20-26™ ; male 15-20. 
It is at once distinguished from V. plewracanthus Stimpson, to which, 
in many characters, it is closely allied, by its very much longer rostrum. 
Among eel-grass about Vineyard Sound, and probably common at 
other points on the coast. 
Virbius pleuracanthus Stimpson, (Aunals Lyceum Nat. Hist., New 
York, vol. x, p. 127, 1871,) abundant upon the coast of New Jersey, will 
very likely be found farther north. In habit it is similar to the spe- 
cies just described.

Malacostraca Podophthalmata Britannia, Pl. 40, 1815. 
Deep water in Vineyard Sound, off Newport, &c. 
North of Cape Cod it is common, and extends to Greenland and En- 
rope. In depth it extends down to 430 fathoms at least.
