This species is in appearance much like granosimanus, but is alto- 
gether distinct. It is readily separated by the front, by the much 
greater proportionate length of the outer portion of the carapace and 
by the very different left hand, and numerous other points. The young 
can be distinguished best by the length of the carapace. 
California. 
Eupagurus beringanus. 
Anterior portion of carapace longer than wide. Median projection 
of the front very obtuse; lateral projections merely indicated. Eye- 
.alks very slender. Eye scales small, triangular; subterminal spine 
slender. A line of hair runs along the eye-stalk from the scale to the 
cornea. The last article of the antennula overreaches the eye by about 
one-half its length. The acicle is small and much curved; hairy along 
the inner margin; reaching nearly to the base of the cornea. 
The right cheliped is stout. The upper margin of the merus is angu- 
-lar,. with a patch of small and very sharp spines near the anterior border, 
which is also spinose. There are two prominent tubercles underneath. 
The earpus is convex on the upper surface, and flattened and compara- 
‘tively smooth on the sides. The granules of the upper surface are 
large and not atall crowded. There are two rows of tubercular granules, 
one on the inner margin and one nearly parallel with it higher up on 
the surface. The hand is the same width as the carpus. Its granules 
are of widely different sizes and are not crowded. A row of tubercular 
granules defines the outer margin. The outer margin of the dactyl has 
a similar border. Fingers with very slight horny tips. 
The small] cheliped reaches a little way beyond the carpus of the large 
one. Its carpus is compressed; upper margin short, armed with from 
ten to twelve slender sharp spines. The oblique triangular face of the 
hand is convex and granular; a deep notch or groove occupies the 
posterior portion of the upper margin. 
The ambulatory legs extend but a trifle beyond the large cheliped. 
The upper margin of the carpal and propodal joints of the first pair and 
of the carpal joints of the second pair are armed with short sharp spines. 
The dactyls are flattened. The legs are hairy. The hair of the upper 
margin is long and arises in tufts or fascicles. 
The distal ends of the joints of the legs are a bright red. Both proxi- 
mal and distal ends of the dactyls are red. The light portions of the 
legs are spotted with red. 
This and the following species from British Columbia are much alike 
‘incolor. The young are difficult to separate. Our specimens come 
from Bristol Bay and north of the Aleutian Islands. 
Eupagurus newcombei. 
Anterior portion of carapace longer than wide. Median projection of 
front very short, obtuse. Lateral projections barely indicated. The
