I. '21. 49 



" Carapace with a sparse covering of long hairs above. 

 Ocular peduncles long and slender, the end of the cornea 

 reaching about as far forward as the tip of the scaphoccrite. 

 The latter is narrow, setiferous, and slightly curved. The 

 flagellum of the outer antennae is sparsely setiferous. The 

 chelipeds are of very unequal size, the right being the 

 stronger ; its chela is convex, oval in outline and smooth 

 in the proximal part (always without spines), with a row of 

 fine points along the curved outer margin ; longer and 

 broader than the carpus. On the upper surface there are 

 two more or less distinct longitudinal ridges running 

 forw^ards, of which the outer, which is the feebler but 

 longer of the two, extends from the junction with the 

 carpus to the angle between the fingers ; the inner, which 

 is sharper but considerably shorter, is seen only near the 

 end towards the carpal joint. The cutting edges of the 

 fingers have teeth of unequal size. The tip of the dactyl 

 is sharply bent. The carpus is long, with almost parallel 

 edges, tapering slightly proximally. The inner edge is 

 serrate. The merus is short with a U-shaped shallow 

 depression on the inside. The underside is broad and 

 thickly covered with long hair. The hand of the left 

 cheliped.is oblong, the carpus laterally compressed, spiny 

 on the inner edge. The merus is short, the underside 

 smooth and strongly setiferous. The two following pairs 

 of pereiopods are long and slender, the second pair some- 

 what shorter than the third. The dactyls are slender, 

 slightly curved, smooth on the lower edge, and not twisted. 

 All the pereiopods are sparsely covered with long hairs. 

 The abdomen is smooth, without hairs." 



Size. — Lagerberg gives the length of the carapace as 5-5 mm. 



General Distribution, — The species is confined to British and 

 Scandinavian waters. Skagerak (Stephensen), Kattegat 

 ^Meinert), Sweden (Lagerberg), Hardangerfjord (Appellof), Shet- 

 lands (Norman), Moray Firth (Henderson), Northumberland 

 (Brady), Guernsey (Henderson), Firth of Clyde (Patience). 



Vertical Distribution, — It is essentially a sub-littoral species, 

 occurring in depths of about five to eighty fathoms.

This species is smaller and more slightly built than A. laevis, 

 from which it may be readily distinguished by the form of the
