CALIFORNIA STALK-EYED CRUSTACEA. 135 



recognized by the bright red tips of the chelipeds and 

 dactyls. Kennerlyi has the spines on the upper surface 

 exceptionally long and slender. Hirsutiusculus, granosi- 

 Tiianus, Samuelis and Hemphillii are small, littoral spe- 

 cies. They are the forms most commonly met with 

 along the shore at low tide. Granosimanus may readily 

 be distinguished from the other three by its rounded, 

 median, frontal projection and its broader left hand. 

 Hirsutiusculus may be recognized by its strong pubes- 

 cence, the short anterior portion of the carapace, and 

 short eye-stalks. 



Subgenus Elassocheirus. 



Pagurus "with the left hand very small, in some cases almost rudi- 

 mentary. The large hand is always wide or broadly ovate, excepting in 

 munitus and Gilli where the carpus is exceedingly- wide and the hand mod- 

 erately so. Eye-scale semicylindrical, grading to triangular, sharp and 

 pointed. Species not hairy; many of them smooth and glabrous." 



Typical species, P. tenuimanus (Dana). 



Besides the type the only species of this group in our 

 limits are munitus and calif orniensis . 



Subgenus Labidocheirus. 



Pagurus "with the manus of the left cheliped cylindrical." 

 Typical species, P. splendescens (Owen). 



Pagurus alaskensis (Benedict). x 



Eupagurus alaskensis Benedict, Proc. U. S. Nat. Mus., Vol. XV, 1892, p. 2. 



Anterior portion of the carapace a little wider than long and sparingly 

 pubescent. Median tooth of the front triangular, acute, and produced 

 considerably beyond the lateral ones, which are rounded, but furnished 

 with a small spine. Ocular peduncles short, stout, constricted in the 

 middle, and about one-half the length of the anterior portion of the 

 carapace. Eye-scales subovate, with the apex blunt or subacute, the upper 

 surface concave and the subterminal spine visible from above. Antennal 

 acicle trigonous, reaching much beyond the tips of the ocular peduncles;
