on the outer distal margins and on the inner upper surface of the merus 
joints of the cheliped. The lower outer surface of the carpal joints of 
.the ambulatory legs are pointed with red. The propodal joints and 
dactyls are longitudinally streaked with red. 
This species is very close to bernhardus, but is easily distin anished by 
its broader and shorter left hand, by the wide dactyls of the ambula- 
tory legs, by the acicula, and by its pearly iridescence. 
Alaska. 
Eupagurus aleuticus. 
Front with three teeth sharper and a little more prominent than in 
alaskensis. The middle or rostral tooth is not quite so much produced. 
Eye-stalks much stouter and some longer than in alaskensis. The eye 
scales are larger and less acuminate. The subterminal spine does 
not show from above. The acicles are broader at the base than in alas- 
kensis. 
The chelipeds are stout. The carpal joints are armed with numer- 
ous sharp spines. That of the left cheliped is three-sided, and not 
four, as in alaskensis. The dactyls of both hands show from above a 
smooth oblique surface, either flat or a trifle concave. In the small 
hand this surface is free from hair and granules; in the large hand it 
is bordered with short spiny granules, and the granules inclosed 
are very small. The spines of both hands are bifurcate, except those 
of the margin, which are simple. The dactyls of the ambulatory legs 
are very wide and thin. The upper surfaces are entirely occupied by a 
sulcus, deep at the base of the article, becoming shallow at the end. 
This character of the dactyls is sufficient to distinguish this species 
from any other species of the bernhardus type. The color is dark in 
most specimens. 
Aleutian Islands. 
Eupagurus patagoniensis. 
Anterior portion of carapace a little broader than long. Front with 
three- rounded lobes equally produced. Lateral lobes armed with 
a single small sharp spine pointing directly forward. The eye-stalks 
are stout, smallest in the middle, dilated and flattened at the corne, 
and enlarged but cylindrical at the base. Eye scales much as in alas- 
kensis. The subterminal spine is black-tipped and shows from above. 
The acicles reach the base of the flagella. In form they are very 
closely like that of bernhardus, and not so much flattened as in the 
related Alaskan species. 
The chelipeds are a little shorter than the ambulatory legs of their 
respective sides. Carpus of large cheliped shaped like that of bern- 
hardus, but it is evenly set with short sharp spines with black points. 
Spines of upper surface of hand black pointed and arranged in about 
seven more or less distinct longitudinal rows. The hand is more than 
twice as long as broad. The outer margin is arcuate; the inner margin
