CRITfOIDEA. 



Distribution. Mediterranean, Eastern side of North Atlantic to 

 Shetland. If the last views of Carpenter (Journ. Linn. Soc. xxiv. 

 (1891), p. 68) are correct this protean species is represented off 

 Bengal, for it would appear that A. duebeni is probably a synonym. 

 Very abundant in places. To 100 fms.

Originally reported from Milford Haven, and since from Arran, 

 Belfast, and mouth of Mersey ; it is very doubtful if this species can 

 be satisfactorily diagnosed. Prof. Wyville Thomson drew up the 

 following : — 



" Perisom of the disk with scattered warts, supported by groups 

 of diverging spicules. Centro-dorsal plate uniformly convex and 

 entirely covered with dorsal cirrhi. Cirrhi of from fifteen to 

 eighteen joints ; the longest of the joints about once and a half 

 as long as broad. Terminal claw curved and acute : penultimate
