24 NEW SPECIES OF HERMIT CRABS—BENEDICT. 
Eupagurus coronatus. 
Anterior portion of the carapace very convex. Median projection of 
the front very sharp, and produced beyond the line of the lateral pro. 
jections. Lateral projections rounded and armed below the margin 
with a sharp spine. Eye-stalks long, stout at the base, tapering for- 
ward to near the cornea, where it is slightly enlarged. Eye scales 
short, rounded, with sharp subterminal spines. Peduncles of anten- —— 
nula and antenna longer than the eye. Flagellum of antenna hairy; 
hairs long and fine. Acicle much shorter than the eye. 
Merus of the large cheliped compressed, short, with a thin subser- 
rate crest on its upper margin. The carpus is also short, stout, and 
with a similar crest. There are two prominent spines near the inner 
angle, also one or more hooked spines on the inner surface. The hand 
is very short, suboval. Itis bordered all around with sharp teeth, sep- 
arated by rounded sinuses. In the larger specimens these teeth num- 
ber about thirty. The surface of the hand is minutely granulose. 
The left cheliped is very small, almost rudimentary. The hand does 
not widen out, nor are the fingers gaping as in the other species. The 
dactyls of the ambulatory legs are short, flattened, spinose. 
This species is widely separated from the preceding species of the 
same group by the very short and crested merus and carpus of the 
large cheliped, and by the eyes and other characters. 
Gulf of California. 
Eupagurus varians. 
Median projection of the front pointed, produced much beyond the 
line of the lateral projections. Lateral projections angular. The eye- 
stalks are stout, constricted in the middle. Cornea much dilated, flat- 
tened. The eye scales are broad at the base, rapidly becoming nar- 
rower, and then drawn out toa fine point. The surface is much hol- 
lowed out-in the distal half of its length. The subterminal spine is 
comparatively very long and stout, and is situated just inside of the 
point of the scale. The long terminal article of the antennula extends 
beyond the eye its entire length. The pedunele of the antenna is also 
much longer than the eye. The acicle is about the same length, or a 
little snorter. The flagellum of the antenna is hairy. The hair is long 
and scattered. 
The merus of the right cheliped is compressed, slightly crested, and 
is produced,down to an angle or tubercle. The carpus is long, narrow 
at the proximal end, widening slightly toward the manus; sides and 
lower surface rounded ; upper surface not well defined, covered with 
short conical spines. The hand is fringed all around with spines 
varying greatly in size. The upper surface is covered with sharp, 
pointed granules, which are much constricted at the base and readily 
detached. In many specimens the hand is suboval, but in large 
specimens the fingers are lengthened and crossed at the tips.
