430 Deej)-sea Trawling off the 8.W. Coast of Ireland: 



front; its inferior surface sqiiamate ; its external surface 

 granular, produced in front below into a bi- or trideutate 

 lobe and above into a single sharp tooth ; the upper surface 

 armed between the two series of teeth with a single bifid 

 tooth. Manus : upper surface bearing a large denticulated 

 keel, which rvrns 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. Dactyliis 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 15^ ; 

 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 10^ ; length of dactylus 9. 



Two female specimens, in shells of Chrysodomus gracilis 

 and Sipho desj^ectus, at depths of 110 and 315 fath. 



Parapagurus pilosimanus. 



Parapagurus jnlosimanus, S. I. Smith, Trans. Coim. Acad. v. p. 61 

 (187U) ; id. Bull. Mus. Comp. Zool. x. p. 20, pi. ii. fig. 4 (1882). 



Specimens, associated with Ejn'zoanthus, from 315 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.
