the coasts of Devon and Cornwall (Bell, Norman, etc.), 

 Norfolk (Patterson) and Northunnberland (Norman). Off 

 the Scotch coast it is rare; Firth of Forth (Scott), Firth of 

 Clyde (Patience). 



Irish distrihution. — Off the Irish coast this species is widely 

 distributed, but not common anywhere. It has been recorded 

 from Sandy cove, Co. Dublin ; in the Strangford and Belfast 

 districts from Portaferry, Donaghadee, Ballyholme Bay and 

 off the Gobbins (Kinahan), and from Larne Lough (Rankin), 

 On the west coast Melville found it off the Arran Is. , Co. 

 Gal way. 



The species was found not uncommonly in Ballynakill and 

 Bofin harbours, Co. Gal way ; in Valencia harbour, Co. Kerry, 

 Miss M. Delap has found a single specimen near Glanleam, 

 and it has also occurred in small numbers in Blacksod Bay. 



Vertical range. —J Attorsil to 30 fathoms (Heller). Off the 

 Irish coast the species has not been taken in more than 15 

 fathoms.

 A eg eon nanus, Norman and Scott, 1906. 



Rostrum short, dorsally hollowed, apex rounded. Cara- 

 pace with two spines in the median line, one in the anterior 

 third and one further back in the posterior third, the latter 

 often reduced to a mere tubercle. On either side are numerous 

 minute tubercles arranged in a more or less longitudinal series ; 

 of these, one row is more pronounced than the rest and con- 

 sists of about fourteen tubercles forming a rather wavy line 

 from close behind the orbit to the posterior margin of the 

 carapace. The line is interrupted at about its middle by a 

 groove which runs backwards and upwards, becoming obsolete 

 before it reaches the median line of the carapace behind the 

 posterior dorsal spine or tubercle. 



Abdominal somites smooth and dorsally rounded, with the 

 exception of the fifth and sixth, on which very obscure 

 tubercles in longitudinal series may usually be observed. Tel- 

 son sulcate above, about as long as the outer uropod. 



Basal joint of antennular peduncle about as long as second 

 and third combined, its subquadrate lateral process not quite 

 reaching the distal end of the segment ; second joint longer 

 than third. Antennal scale (fig. 4 b) rather narrower than in 

 the preceding species — slightly more than two and a half times
