Fig. 87. Pagurus beringanus, X V/ 7 (U. S. N. M.). 



Characters. — Median projection of front short and low, very blunt, or broadly 

 rounded. Small clieliped with outer face of hand flat-triangular, forming a dis- 

 tinct angle with the smooth though hairy inferior or lower face; carpus with 

 upper or anterior edge with eight or more close set, equidistant spines in a row, 

 occasionally but rarely with a smaller number of spines. Large hand more or 

 less coarsely and irregularly granulate, granules at times tending to become spini- 

 form tubercles, always with a distinct A -shaped design of larger granules from 

 base of inner edge of immovable finger to base of palm, inner arm of A continued 

 on carpus to its proximal inner angle ; immovable finger slightly excavated on 

 upper surface, making tip appear bent upward. Ambulatory legs quite or very 

 hairy. 



Dimensions. — Type, male: length of carapace from tip of rostrum to posterior 

 border of carapace, 21 mm., length of larger cheliped 45 mm. 



Color. — The distal ends of the joints of the legs are bright red. Both proximal 

 and distal ends of dactyls are red. The light portions of the legs are spotted 

 with red (Benedict). 



Type Locality. — Bristol Bay, 12 fathoms ("Albatross" station 3231). 



Distribution. — Bering Sea (latitude of Nunivak) southward, along the Aleutian 

 Islands and coast of Alaska to Monterey, California, 5 to 19 fathoms (Bathbun). 



Remarks. — P. newcombei (Benedict) is included in P. beringanus, as it seems 

 to be scarcely distinct. The species varies in the sharpness of the tubercles or 

 spines of the chelipeds (Bathbun).
