10 NEW SPECIES OF HERMIT CRABS—BENEDICT. 
ginalspine. Eye-stalks smaller than in brandti. Eye scales triangular, 
with a large subterminal spine. The acicles reach but little beyond the 
eyes. 
The width of the carpus of the large cheliped is less than two-thirds 
of its length, while the hand is more than twice as longas broad. The 
outline of the hand is nearly the same on both margins. The fingers 
are a little hooked, and the points cross wien the fingers are closed, 
giving the pollex the appearance of being a little longer than the dac- 
tyl. The spines of the carpus and hand are small, slender, and sharp. 
The small cheliped has a triangular outer face. 
The ambulatory legs are slender, the dactyls on the right side ex- 
tending beyond the cheliped by about one-third their length. The 
dactyls are spinulose, a little curved, but notat alltwisted. The cheli- 
peds and ambulatory legs are hairy; the hair is very fine and not very 
conspicuous. 
Alaska. 
Bupagurus tanneri. 
Front tridentate; teeth pointed, well defined. Rostriform tooth much 
larger and more produced than the lateral teeth. Ocular peduncles 
stout; corne dilated ; scales ovate, with subterminal spine prominent, 
pointed. Second article of antenna short, stout; its outer angle pro- 
duced to or beyond the middle of the penultimate article; inner angle 
armed with aslender spine. Acicle thin and flattened at its base, 
slender and subcylindrical for the greater part of itslength. It reaches 
beyond the middle of the last article. 
Right cheliped long, its merus extending beyond the eye for two- 
thirds of its length. Upper and outer side of merus cylindrical, its 
distal surface rendered uneven by tubercles and hairy ruge, the rug 
becoming shorter at the proximal end.. Carpus four-sided ; upper side 
a little convex; much more so below; sides concave. Hand elongate, 
about as wide as the carpus; from about the middle of the palm it 
tapers gradually each way. Fingers thin and bent downward like 
curved scissors. A ridge beginning at the articulation of the carpus 
near the inner angle of the hand, runs diagonally across the hand and 
along the inner portion of the immovable finger. Another ridge be- 
ginning near the outer proximal angle of the hand runs across the 
hand and joins the first ridge a little behind the gape of the fingers. 
At this point the ridge is most elevated. The two ridges inclose a sub- 
triangular area, ili which there are five or six short spines. The ridges 
are spiny, the first one from its origin to the pollex, the second through- 
out itslength. Both margins of the hand are spiny. On the outer 
margin the spines are regularly placed ina single row, extending to 
near the tip of the pollex. On the inner margin they form a double | 
row, irregularly placed. There is a single row of spines on the margin 
of the dactyl. A row higher up unites,with the first near the tip. 
Two marked depressions occupy the large part of the upper surface of
