430 Deep-sea Trawling off the S.W. Coast of Ireland : 
front; its inferior surface squamate; its external surface 
granular, produced in front below into a bi- or tridentate 
lobe and above into a single sharp tooth; the upper surface 
armed between the two series of teeth with a single bifid 
tooth. Janus: upper surface bearing a large denticulated 
keel, which runs from the middle of the posterior margin to 
the extremity of the dactylar prolongation of the manus ; 
externally and internally to this keel, except internally on 
the surface of the dactylar prolongation, where it is smooth, 
the upper surface is very finely and closely granular, and the 
external and internal margins are obscurely denticulate ; the 
inferior surface is rounded, smooth, and sparsely but deeply 
punctured, and sparsely hairy. Dactylus smooth above and 
below, and furnished with small tufts of hairs. 
Ambulatory limbs externally and internally smooth ; in the 
first pair the merus is spiny beneath, and the carpus and 
propodus spiny above; in the second pair the carpus is spiny 
above and the propodus obscurely so; dactyli considerably 
longer than the propodi, and curved. 
The penultimate abdominal tergite is marked by a median 
transverse constriction. 
Colour (in spirit). The cephalothorax dirty white, with a 
patch of red on each side of the anterior portion ; reddish 
tints about the bases of the ophthalmopods; the appendages 
pale pink, paler towards their distal extremities, and with 
darker patches here and there. 
Measurements (in millimetres). Length of carapace 154; 
right chelipede—length of merus 9°10, of carpus 14, width of 
carpus 9; length of manus (to articulation of dactylus) 9, width 
of manus 103; length of dactylus 9. 
Two female specimens, in shells of Chrysodomus gracilis 
and Sipho despectus, at depths of 110 and 3165 fath. 
Parapagurus pilosimanus. 
.Parapagurus pilosimanus, 8. I. Smith, Trans. Conn. Acad. v. p. 51 
(1879) ; id. Bull. Mus, Comp. Zool. x. p. 20, pl. ii. fig. 4 (1882). 
Specimens, associated with Epizoanthus, from 3815 to 
1000 fath. 
This species is abundant on the N.-American side of the 
Atlantic, and was obtained by the ‘ Albatross’ at a depth 
exceeding 2000 fath. I am not aware that its occurrence 
within the limits of the so-called British area has been 
reported before.
