This species is not uncommon in deep water off the New England coast, and 

 is found at least as far south as off the Capes of the Delaware, where it has been 

 taken in abundance by Capt. Z. L. Tanner, of the U. S. Fish Commission 

 steamer " Fish-Hawk," Station 1045, N. Lat. 38° 35', W. Long. 73° 13', 312 

 fathoms.

This species almost entirely replaces P. Montagui south of Cape Cod, and 

 appears to be everywhere exceedingly abundant in from 30 to 200 fathoms, but 

 below 300 fathoms it seems to give place to P. propiiiquiis. 



In size and general appearance it is much like P. Montagui but more slender 

 and readily distinguished from it, and from P. ■propinquus and borcalis as well, 

 by the minutely roughened surface and the presence of exopods upon the ex- 

 ternal maxillipeds. 



The rostrum is from about once and a third to nearly twice as long as the 

 rest of the carapax, and curved very slightly upward, but usually not as much 

 so as in P. Montagui. Above, it is armed with eleven to thirteen teeth, of 

 which one is near the tip, as in P. Montagui, and usually only two back of the 

 orbit on the carapax proper, while a considerable space l)ack of the terminal 

 spine is unarmed, though this space is usually shorter than in P. Montagui. 

 Beneath, there are six to eight "teeth, as in P. Montagui. The entire surface of 

 the carapax and abdomen is slightly roughened with short and irregular, trans-
