The merus of the right cheliped is trihedral. The upper surface of 
the carpus is triangular and granulose; outer margin slightly upturned; 
inner margin armed with six or seven long slender spines, curved and 
projecting forward. The hand looks solid and smooth to the eye, but 
with a lens the surface is seen to be finely and beautifully granulated. 
The crest isnot spiny, but is composed of oblong flattened tubercles, even 
in height and regular. The lower margin is finely bordered by granules. 
The dactyl is short and stout; surface evenly rounded at the margin, 
which is hardly apparent, but yet marked by an inconspicuous line of 
small granules. The lower surface is about as the upper. 
The ambulatory legs are moderately stout. The dactyls are straight 
and armed with spinules. 
There is a wide band of orange near the base of the eye-stalk and on 
the antennal peduncle at the base of the acicie. The hand is a light 
pink, while the carpus is a much darker shade of the same color. The 
ambulatory legs are banded with orange. 
The single alcoholic specimen from which the description was made 
_ was taken in the Gulf of California by the steamer Albatross. The left 
pes 
hand was lost. 
Eupagurus corallinus. 
Median projection of the front rounded, much produced beyond the 
lateral. Lateral projections rounded, unarmed. IlHye-stalks largest on 
the distal end; cornez dilated. The eye scales are sharp-pointed, with 
Prominent subterminal spines. The antennular and antennal peduncles 
are much longer than the eye, and the acicle is a trifle shorter. 
The merus of the large cheliped is compressed, its lateral aspect 
quadrilateral. The carpus is alittle longer than the palm; its upper sur- 
face is thickly set with very sharp spiny granules; the margins are defined 
by rows of spiny granules. The hand is fringed with spines alternately 
large and small, the spines becoming longer towards the apices of the 
fingers. The entire upper serface is thickly set with very small, slen- 
der, sharp spines. The spines along the fingers are very much enlarged 
in the center and constricted at the base. 
The merus of the left cheliped is much compressed. The carpus is 
compressed and surmounted by a double row of spines; in the outer 
row, large; in the inner, small. The hand is wide and thin; fingers 
gaping at the base; entire surface covered with very small sharp gran- 
ules. The carpal joints of all and the propodal joints of the anterior 
pair of ambulatory legs are crested with spines, a little large in propor- 
tion to the size of the animal. The dactyls are wide, thin, curved, 
and spinulose. 
Color.—The meral and carpal joints of the large cheliped are blotched 
with red and whiteywhile the small cheliped and the ambulatory legs 
are banded with the same colors.
