Eupagurus kennerlyi Stimpson.* 
Anterior portion of carapace a little longer than broad. Median 
projection of the front short, triangular. The lateral projections are 
rounded, but have a sharp appearance from the submarginal spine. 
The eye-stalks are straight, slender. The scales are acute, with large 
_ subterminal spines. The acicle of the antenna is slender, hairy, and 
does not reach to the end of the eye-stalk. 
The merus of the large cheliped is nearly trihedral; outer surface 
smooth, without ornamentation of any kind; lower margin spiny. The 
carpus is Set on the inner margin with seven or eight slender curved 
spines. The hand is a little wider than the carpus, and is traversed by 
seven rows, including the marginal rows, of slender light-colored spines. 
The prehensile edges of the fingers are armed with stout tubercles ; 
tips horny. 
Merus of left cheliped compressed; lower margins spiny. The ecar- 
pus is a little compressed, bicristate. The hand reaches a little be- 
yond the base of the dacty] of the large hand ; it has an outer trigonal 
surface well set withlarge spines. Fingers horny-tipped. Ambulatory 
legs stout. Color in alcohol reddish. 
Alaska. 
Eupagurus setosus. 
The carapace is very convex, little longer than broad. Median pro- 
jection of front rounded, a little in advance of the lateral projections. 
The eye-stalks are much stouter and shorter than in kennerlyi. The 
scales are very small and acute, with large subterminal spines. ‘The 
acicles of the antenne reach beyond the eye one-fourth of their length. 
The chelipeds have very much the same form as in kennerlyi, but the 
spines throughout are much shorter. The fingers are armed on the 
prehensile edges with large tubercles; points horny. The merus of the 
small cheliped is compressed. The carpus is thick, bicristate; sides 
compressed. The hands of both chelipeds are thickly set with stiff 
bristles, which character will separate the species at sight from ken- 
nerlyz. Color in alcohol light yellow. 
Alaska. 
Subgenus ELASSOCHIRUS. 
Eupagurus munitus. 
Anterior portion of carapace very smooth, with an occasional tuft 
of hair and a few pits or small, shallow depressions on the lateral re- 
gions. Front tridentate; teeth of nearly equal prominence. Eye scales 
long, sides subparallel, edges upturned, making the surface deeply con- 
cave; the ends round; subterminal spine not showing from above. The 
first article of the antenna is armed with a very small spine which points 
forward and outward. The inner angle of the second article is armed
