270 Dr. W. C. M'Intosh on the 



Subdivision Domicola. 



Fam. Corophiidae. 



Subfamily Podocerides. 



Genus Amphithoe, Leach. 



Amphithoe rubricata, Mont. ; B. & W. op. cit. i. p. 418. 

 In the debris of the fishing-boats. 



Amphithoe podoceroides , H. B-athke ; B. & W. op. cit. i. p. 422 



(as A. littorina). 



Common in the laminarian region, and under stones between 

 tide-marks, where it constructs tubes or nests. Most of the 

 fine specimens have the hand of the second pair defined by a 

 distinct tooth, as Bathke and Dr. Johnston state. 



Genus Podoceeus, Leach. 



Podocerus falcatus, Mont. ; B. & W. op. cit. i. pp. 436 & 447 (as 

 P. pidchellus and P. pelagicus). 



In rock-pools on Ceramium rubrum at the Pier, in the 

 laminarian region beyond, in the stomachs of flounders, and 

 in the fishing-boats. Sometimes gaudily tinted with reddish 

 brown and white, and with red bars on the inferior antennae. 



Podocerus variegatus, Leach; B. & W. op. cit. i. p. 439, & p. 442 



(as P. capiUatus). 



Not uncommon in pools near low-water mark at the 

 East Eocks. 



Genus Ceeapus, Say. 



Cerapus diffbrmis, M.-Edwards ; B. & W. op. cit. i. p. 457. 



Common in deep water. The straw-coloured body is marked 

 with dark grains ; and the superior antennas have the basal 



third of the second and thirc 



segments tinted of a crimson 



hue, the flagellum being similarly coloured for its proximal 

 half; the eyes have black centres and, as usual, a pale 



margin. 



Genus Siphoncecetus, Kroyer. 



Siphonoecetus typicus, Kroyer ; B. & W. op. cit. i. p. 465. 



Abundant in the laminarian region in 3 to 6 fathoms off 

 the East Bocks, where it constructs nests on the inner surface 

 of bivalve shells. 8. Whitei, Gosse, is probably the female of 

 this species.
