The rostral projection well marked. Chelipecles tuber- 

 culate, with a tendency to become spinose, especially on the 

 inner border of the carpal joints. Ambulatory limbs spiny 

 on the upper borders, the dactyli long and slightly contorted. 

 Length, 4|^ inches. 



Hah. — British seas everywhere, from between tide-marks 

 down to the greatest depths obtainable; throughout the 

 ISTorth Sea, as far north as Finmark (Sars) ; and the Arctic 

 seas. It is apparently absent from the Mediterranean, but 

 occurs in the Baltic (Mobius). It ranges along the Atlantic 

 shores of North America as far south as Long Island (Stimp-

 Kamtschatka.

The rostral projection not prominent. Chelipedes granu- 

 lated, the carpal joints tuberculate on their inner margins. 

 Ambulatory limbs almost smooth, the dactyli grooved longi- 

 tudinally on each side and not contorted. Internal antennae 

 half as long again as the ocular peduncles. The squame of 

 the external antennae more slender and less curved than in 

 U. Bernhardtcs. Length, 4 inches.

 far north as the Shetland Islands. It occurs in the Moray 

 Firth (Gordon and Edward), but is apparently absent from 

 the remainder of the east coast of Britain. A shallow-water
