CALIFORNIA STALK-EYED CRUSTACEA. 139 



wide and rather sparsely set with sharp, stout spines. Hand of smaller 

 cheliped narrow, slender, with the supero-external surface narrower than 

 in trigonocheirus, and the edges not so strongly produced. Dactyls of the 

 ambulatory legs slightly twisted. 



Very near pubescens from the Atlantic. For an enu- 

 meration of the differences, see Benedict, 1. c, p. 9. 

 Alaska; Washington in 40 fathoms (Benedict). 



Pagurus Brandti (Benedict), 



Eupagurus Brandti Benedict, Proc. U. S. Nat, Mus., Vol. XV, 1892, p. 9. 



Median portion of the front triangular and produced scarcely beyond 

 the lateral teeth. Eye-stalks rather stout. Acicles scarcely extending 

 beyond the eyes. Hand of the larger cheliped twice as long as wide. 

 Hand of the smaller cheliped as in trigonocheirus. Ambulatory legs almost 

 entirely unarmed; dactyls slender, slightly twisted and longer than the 

 propodi. Color of alcoholic specimens " everywhere reddish. Spines K, 



everywhere red or red pointed." 



Aleutian Islands (Benedict); Captain's Harbor, Una- 

 laska, 80 fathoms! 



Pagurus Dalli (Benedict). 



Eupagurus Dalli Bexedict, Proc. U. S. Nat. Mus., Vol. XV, 1892, p. 9. 



Very closely allied to Brandti. Median lobe of front triangular, acute, 

 and produced further beyond the lateral teeth than in Brandti. Eye- 

 peduncles more slender than in Brandti or trigonocheirus. Acicle reaching 

 but little beyond the eyes. The carpus of the small cheliped is not so 

 high, and the supero-external surface of the hand is not nearlj^ so wide at 

 the base as in the last two species. The dactyls of the ambulatory legs 

 are long, more slender than in Brandti, and not twisted. 



Aleutian Islands, Unalaska (Benedict); Iluliuk Har- 

 bor, 10 fathoms! 



'' This species," says Benedict, ''is closely allied to 

 Kroyeri, trigonocheirus, and Dalli. The small chelipeds 

 of all have the triangular outer face, and in general the 

 species resemble each other very much. With a large 

 series of all I find substantial specific characters.
