long, stout. Scales short, rounded, with a slender subterminal spine. 
Acicle of antenna shorter than the eye. Peduncle scarcely if any longer 
than the eye. 
Merus of right cheliped short, compressed. Upper surface of car- 
pus triangular; inner margin armed with slender spines; a few scat- 
tered spines on the surface. The hand is much longer than wide. The 
inner margin of the manus is set with long slender spines, as also the 
outer edge of the dactyl. Spines of the outer margin much smaller. 
Two rows of slender spines beginning at the carpus run together at the 
base of the pollex. 
Carpus of left cheliped single-crested with slender spines. The ob- 
lique subtriangular face of the hand is bordered by very sharp spines. 
The upper surface is about equal to the oblique surface in extent. 
The specimen is hairy. 
Gulf of California. 
Eupagurus purpuratus. 
The median projection of the front is rendered sharp by a rostral 
point which originates on the upper surface and extends beyond the 
margin. The triangular lateral projections are not armed witha spine. 
The eye stalks are stout and long. The eye scales are acute, concave, 
and have a prominent, slender, subterminal spine. The lateral pro- 
jection of the second article of the antennal peduncle is long and is con- 
spicuously armed with spines on its inner margin. The peduncle is but 
little ifany longer than the eye. The acicle is setose and much shorter 
than the eye. The peduncle of the antennula is much longer than the 
eye. 
The carpus of the large hand widens out evenly from the merus, 
making the outline straight; outer margin unmarked by special line of 
granules or spines; inner margin defined by a row of five or six spines 
which are very sharp and point forward; upper surface coarsely gran- 
ulated. The hand has a symmetrical outline and is fringed from the 
tips of the fingers to the wrist with blunt spines. Those on the outer 
margin originate on the lower surface and project above the upper sur- 
face. <A strong ridge beginning at the tip of the dactyl runs backward 
and is continued on the manus and ends at the wrist. The whole upper 
surface of the hand is paved with large fattened compound granules. 
These granules seem to be hemispherical and a little elevated above the 
true surface, often showing irregular shaped fissures between them. 
The tubercles or spines on the inner margin of the hand are not so 
thickly set as on the outer. 
The carpus of the small cheliped has a single crest armed with three 
or four strong spines. The hand has a curved oblique face and also a 
horizontal face equally prominent. This hand is also paved with com- 
pound granules. The lower margin of the oblique face is sparsely set 
with tubercles,
