6 NEW SPECIES OF HERMIT CRABS—BENEDICT. 
in pollicaris. The upper margin of the carpal and propodal joints of 
the ambulatory legs are spinuiose. The dactyls are slender, curved 
and twisted. 
Florida. 
Bupagurus exilis. 
Carapace flattened, depressed, wider than long. Front with a sharp 
triangular rostral tooth in line with the much rounder lateral lobes, 
which are armed with two short sharp spines directed forward and out- 
ward. The eye-stalks are short and stout, flattened at the corne. 
The scales are short, wide, and round at the end, the subterminal spine 
not showing ordinarily from above. Aciculze of the antenne not quite 
reaching the extremity of the eyes. 
Chelipeds long and slender. The carpus is about as in longicarpus. 
The hand is much more than twice as long as broad, about equally | 
arcuate on both margins. The fingers are slightly hooked at thetips. | 
The left cheliped is as in longicarpus with the exception of a raised row 
of granules on the outer margin of the pollex. 
The dactyls of the ambulatory legs are log, slender, curved, and 
twisted. The upper carpal margins are set with a row of small spines. 
These do not exist in longicarpus. 
This species, while very closely related, is sufficiently distinct from 
longicarpus. 
Off the Rio dela Plata. 
Eupagurus albus. 
beyond the lateral projections, which are also angular and are armed 
with a short spine which points outward. This spine or point does not 
arise below the margin, as is commonly the case with spines at this 
point, but is produced from the slightly raised margin. The eye-stalks 
are Short, stout, and flattened; the corne are dilated. Eye scales 
Short, triangular, wide at the base; the subterminal spine very small, 
sometimes seen from above, often not. The peduncles of the antennula 
and antenna extend beyond the eyes. The acicles are about as long as 
the eyes. 
The right cheliped is long and slender. The upper anterior margin 
of the merus is armed with a few stout conical spines. The carpus is 
flattened on the inner surface and much rounded above and on the 
outer side. The upper surface is longit udinally divided into two parts 
by a median line of small spiny granules. The surface of the inner 
division is concave; the outer is convex. The handis long, narrow, and 
is very Slightly bent upward. The surface above and below is thickly 
set with rough, flattened granules. The inner border is conspicuously 
marked by araised ridge. . The fingers are slender andshorter than the 
palm. | 
The small cheliped barely reaches the large hand in large specimens. | 
Front with median projection angular, not produced much if at all
