tirely bordered with spines, and its surface is horizontal and covered 
with plates, as in the large hand. 
The ambulatory legs are moderately stout, with slender, curved, and 
twisted dactyls. The carpal and propodal joints are crested with spines. 
The spines on the propodal joints of the second pair are very small. 
The dactyls are broadest two-thirds of their length from the propodal 
joints and are bordered with hair above and with spines and hair below. 
The color in alcoholic specimens is pink. 
Gulf of California. 
Eupagurus impressus. 
Anterior portion of carapace about as broad as long, flattened. 
Rostral projection on a line with lateral projections, much rounded. 
Lateral projections angular. EHye-stalks long, slender, dilated, and 
flattened at the corne. Scales semioval. Subterminal spine large. 
Acicule slender, very hairy, not extending beyond the eye-stalks. 
The chelipeds are stout and strong. The large hand is much wider 
than the carpus. Its outer margin is arcuate, set with about twenty 
blunt teeth. The inner margin is without marginal spines or granules 
except at the distal end of the dactyl, where the margin beyond the 
angle is spiny. The upper surface is covered with granular plates, 
making a nearly even surface above the true surface. There is a de- 
pression near the outer margin opposite the base of the dactyl, and an- 
other running from the carpus nearly to the gape of the fingers in 
each hand. 
The left hand is broader in proportion to its length than the right. 
Its surface is about the same in character. The arcuate outer margin 
is set with teeth, with small angular projections near the base of each. 
The inner margin is nearly straight, behind the dactyl having a row 
of five or six teeth. The margin of the dactyl is tuberculate. 
The ambulatory legs extend but little beyond the cheliped. The 
dactyls are hairy and alittle bent and twisted. 
This species is allied to pollicaris. 
Florida. 
Eupagurus floridanus. 
Anterior portion of carapace wider than long. Rostral projection 
rounded; lateral projections angular and a little in advance of the ros- 
tral. Eye-stalks slender, much flattened and dilated at the cornee, and 
dilated at the base. Eye scales elongated, conical, with a large sub- 
terminal spine. The acicule of the antenne do not extend beyond the 
the eye. ‘The ultimate joint of the antennule is more than twice as 
long as the penultimate. 
The chelipeds are very much as in pollicaris, but the hands are much 
narrower. The angle of the outer margin of the dactyl of the large 
hand is much nearer its base. The outer margin of the hand is not 
so much rounded and the bordering granules are not so prominent as
