428 Deep-sea Trawling off the S.W. Coast of Ireland : 
Eupagurus excavatus (Herbst). 
Eupagurus excavatus (Herbst), Henderson, loe. cit. p. 70. 
Two specimens from 110 fath. 
Taken on the west coast of Ireland by the ‘ Porcupine ’ 
expedition, and ranging from Senegambia to the Shetlands. 
Hupagurus carneus, Sp. Nl. 
Carapace with posterior and lateral portions membranous ; 
anterior portion smooth, slightly convex from before back- 
wards, more so from side to side, the median frontal pro- 
jection well marked and sharp, the lateral less marked than 
the median and each tipped with a minute spine. 
Ophthalmopods stout, with dilated corneze and small tufts 
of hairs, projecting slightly beyond the second segment of the 
antennular and antennal peduncles; the scale small, narrow, 
and spatulate, being hollowed out above and bearing a small 
forwardly directed tooth below. 
Antenne. Basal segment bearing distally one spine on the 
upper inner margin, asecond slightly longer on the inferior 
surface and externally, and a third very large one which, supe- 
riorly denticulate, extends as far as the distal end of the second 
segment; acicle slender and outwardly curved, projecting to 
about the middle of the distal segment of the peduncle; the 
whole of the peduncle more or less hairy. 
Chelipedes very unequal in size, the right being much 
larger than the left. In the right the merus is trigonal, with 
convex internal and external surfaces; the external surface 
squamate, internal surface almost smooth; the external edge 
of the lower surface is finely denticulated, and prolonged 
in front into a spine; the internal edge of the lower surface 
bears proximally two larger blunt teeth ; the anterior edge of 
the upper surface bears about five separated sharp teeth. 
The carpus is large, being longer than the greatest length of 
the merus by about one third of its own length; the upper 
surface slightly convex from before backwards and from side 
to side, proximally a little squamate, but the rest of the 
surface thickly covered with exceedingly minute close-set 
granules ; the external and internal margins of this surface 
very well marked; the external margin slightly raised, denti- 
culated in the middle, and gradually converging towards the 
meral articulation ; the internal margin much more strongly 
marked, dentate throughout its extent, and abruptly con- 
verging towards the meral articulation ; external surface 
more coarsely granular than the superior surface, and armed 
in front with a few small denticles; the inferior surface
