Eupagurus Samuelis, Stimpson ; Proc. Bost. Soc. Nat. Hist. vi. 86. 



Front acute at the middle. Outer antennae articulated 

 at the extreme antero-exterior corners of the carapax ; ex- 

 tremity of terminal article of peduncle reaching much 

 beyond the eyes; flagellum reaching the extremity of the 

 Larger hand. Anterior feet very unequal in size, the right 

 being ranch the longer and stouter; carpus and hand gran- 

 nlated; larger hand nearly twice as long as broad; finger 

 less than half as long as the hand, with a slight crest not 

 conspicuously denticulated. Left hand narrower than its 

 carpus, which has a slightly prominent double crest. Feet 

 of the second and third pairs very slender, somewhat hairy ; 

 the right foot of the second pair longer than that of the first 

 pair. Color yellowish. Length three fourths of an inch. 



This is a very small species, found in shells of the genera 

 Nassa, Liftorina, etc. It most resembles E. tcnuimanus, 

 from which, however, it may be distinguished by its more 

 oblong, non-cristate hand. From E. Middendorffii it differs 

 in the more prominent granulation of its anterior feet, and 

 the more numerous and smaller teeth on the inner margin 

 of the thumb and finger. 



It was taken in Tomales Bay, near low-water mark, by 

 Mr. Samuels, to whom I have dedicated the species, as a 

 memorial of his labors in this department of science. It is 

 in the Museum of the Smithsonian Institution.
