276 Mr. E. J. Miers on Crustacea from 
Pagurus granulimanus, sp. n. 
(PI. XVI. fie. 3.) 
This designation is proposed for a species of Pagurus of 
which there are several specimens inhabiting shells of Cassz- 
dulus morio, Lamk., Purpura hemastoma, Lam., and Natica 
cruentata, Lam., in the collection. 
Carapace one and a half times as long as broad, with the 
cardiaco-branchial as well as the cervical sutures distinctly 
defined, punctulated in front of the cervical suture, with a few 
granulations near the antero-lateral angles; hepatic and 
branchial regions clothed with tufts of yellowish hairs; no 
distinct median rostriform projection ; terminal postabdominal 
segment somewhat quadrate, with the angles rounded. Hye- 
peduncles slender and nearly or quite equalling in length the 
width of the frontal margin ; ophthalmic scales narrow, nearly 
approximated in the median line, and with the apices denti- 
culated. Antennules reaching little beyond the eye-peduncles ; 
terminal joint of the peduncle slender and longer than the 
preceding ; flagella very short. Antenne shorter than the 
body, with thin basal acicles, rather narrow, acute at apices, 
reaching about halfway to the end of the eye-peduncles, and 
very hairy; the joints of the peduncle are very short, the 
penultimate joint has a short spine on the under surface near 
its. distal end; flagella nearly naked. The last three joints 
of the outer maxillipedes have their under margins near the 
than the right. Length of the largest specimen about 5} inches (133 
millim.), of the larger (left) chelipede about 53 inches (88 millim.). 
The ground-colour of the specimen described (which was presented by 
H. E. Dresser, Esq., and at the time of its acquisition by the Trustees had 
been preserved for some time in spirit) is orange-yellow, the front of the 
carapace and eye-peduncles variegated with purple; the prevailing colour 
of the limbs is a deep blood-red. In a second smaller example from the 
same locality (J. C. Melliss, Esq.) the coloration is not so distinct. Both 
examples are males. 
There are several species allied to P. emperator in the structure of the 
left lex of the third pair. In P. setfer, M.-Edwards, from Australia (of 
which there are specimens in the Museum collection), and in P. sevlptipes, 
Stimpson, from Japan, the eye-peduncles are much longer and slenderer ; 
in P. parimentatus, Hilgendorf, the hand of the left chelipede is much 
shorter in proportion to its length; P. hungarus, Herbst, is very imper- 
fectly known; but Hilgendorf, m his remarks upon the specimens in the 
Berlin Museum, does not mention any differences from P. pavimentatus 
in the form of the left chelipede. In P. stnistripes, Stimpson, from 
Panama, the outer surface of the left chelipede is described as granulate- 
squamose, and the last two joints of the left leg of the third’ pair are 
apparently but little excavated. A much larger series than the Museum 
at present possesses is needed to show whether these are truly distinct or 
may not be, some or all, varieties of one widely-distributed form.
