168 BULLETIN OF THE 
et Bouv., compared with C. tanneri, displays longer eyestalks, while the thorax 
and abdomen are less pubescent, and the coxal segments of the posterior legs are 
much more protuberant. 
Length of carapace, 7 mm. ; breadth, 5 mm.; length of eyestalk, 3 mm. 
Station 3368. 66 fathoms. 1 male. 
Found in a cavity in a piece of dead coral rock. 
The abdomen in the unique type specimen is not quite symmetrical, but this 
may be an individual peculiarity resulting from the shape of the cavity in 
which the animal lived. 
Pylopagurus longimanus, sp. nov. 
Carapace smooth, naked, polished ; rostrum ‘short, triangular, subacute, ad- 
vanced farther than the rounded lateral anglos. Abdomen longer than cephalo- 
th-rax. Eyestalks equal in length to the first two segments of the antennulary 
peduncle. Ophthalmic segment uncovered. Ophthalmic scales separated by 
a considerable interval, triangular, their tips split in a horizontal plane so that 
they end in two acute teeth, one above the other, the lower tooth the longer. 
Last segment of antennulary peduncle very long and slender (much longer 
than the eye-stalk). Right cheliped of enormous size, much exceeding the 
whole body in length ; the outer face of the merus is nearly smooth, the lower 
and inner faces granulated ; carpus very large, equalling in length all the pre- 
ceding segments combined, its surface granular, the granules assuming the form 
of small spinulose tubercles on the dorsal face, which is limited within by a 
row of larger teeth. Chela irregularly oval, the external side flattened to form 
an opercular facet, which is thickly set with granules and surrounded with a 
margin of denticles. Left cheliped very small, its segments more hairy than 
those of the right ; basal part of propodus short and swollen, the fingers long, 
gaping at the base; the outer or upper faces of the propodus and dactylus are 
granulated, and definitely bounded by a line of regularly arranged granules on. 
the outer margin of the dactylus and the inferior margin of the propodus; the 
inner or lower face of the chela is pretty free from granules, but is furnished 
with numerous sete, those on the dactylus being grouped in conspicuous tufts 
or pencils, Penultimate pair of thoracic appendages almost perfectly chelate, 
its rasp restricted to the distal part of the claw, broad, and composed of many 
rows of scales. 
The legs are yellowish, banded and mottled with red. 
Length of carapace, 10 mm.; eyestalk, 4 mm.; right cheliped, 34.5 mm. 
(merus, 8 mm.; carpus, 11 mm.; propodus, 14.8 mm. ; dactylus, 10 mm.). 
In younger, smaller specimens the chelipeds are shorter in proportion to the 
length of the body, and the major claw is shorter, broader, and of a more regu- 
lar oval form. A specimen, whose carapace is 6.5 mm. long, gives the follow- 
ing dimensions for the right cheliped : total length, 16.5 mm.; merus, 4.5 mm. 5 
carpus, 5.5 mm.; propodus, 7.5 mm.; dactylus, 4.5 mm.
