North Carolina to Labrador and Europe. In depth it extends from 

 low water to 60 or 70 fathoms, and probably much deeper. 



I HIPPOLYTE PUSIOLA Kroyer. (p. 395.) 



Mouogruttsk Fremstlling Hippol., p. 319, PI. 3, figs. 69-73, 184-2. 



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 antennae Inner flagellum of the anteunula ex 

 tending very slightly beyond the tip of the antenual 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 mm ; male 15-20. 



It is at once distinguished from V. pleuracanthus Stimpsou, 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 pleuramnthm Stimpsou, (Annals 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?, PI. 40, 1815. 



Deep water in Vineyard Sound, off Newport, &c. 

 North of Cape Cod it is common, and extends to Greenland and Eu 

 rope. In depth it extends down to 430 fathoms at least.
