 Eupagurus excavatus (Herbst), Henderson, loc. 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. 



Eupagurus carneus, sp. n. 



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. 



Ophthalmoj)ods stout, with dilated cornege 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 tootli below. 



Antennce. Basal segment bearing distally one spine on the 

 upper inner margin, a second 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 tlie 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. Tn 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
