ORDER AXIFERA. 



FAMILY IS1DAE. 



Ceratoisis Grayi, E. P. Wright. 



Helga, CXX. 77 mi. W.N.W. of Achill Head; 382 fms. ; 

 24th August, 1901. 



" The original specimen of this species was obtained in 

 deep water off Setubal on the coast of Portugal and was 

 " described by E. P. Wright (1869) in a short paper illus- 

 trated by two good figures. In the Challenger Mono- 

 graph Wright and Studer state (1889, p. 278) that the 

 " species was obtained off the Cape Verde Islands, but I 

 ' ' can find no other reference in the literature to any speci- 

 " men from this locality, and I am inclined to believe 

 " that it is a mistake. Gray (1870) states that the type 

 "specimen was obtained from a depth of 400 fathoms. 

 ' There can be no doubt that the specimen from Achill 

 " belongs to this species. The specimen at my disposal 

 " is small, 25 mm. long, and I have not used it for making 

 ' ' preparations ; but a good description with figures of the 

 " spicules is a desideratum. A specimen assigned by 

 " Eoule to C. flexibilis of Verrill was found by the Caudan 

 "expedition in 1,410 metres in the Bay of Biscay."

Acanella arbuscula, Johnson. 



Helga, CXX. 77 mi. W.N.W. of Achill Head ; 382 fms. ; 

 24th August, 1901. 



" The small specimen which I possess seems to be 

 " identical with this species. A. arbuscula was found by 

 "the Caudan expedition at four stations (950-1,710 

 " metres) in the Bay of Biscay, and more recently by the 

 " Huxley expedition in the Bay of Biscay in 410 fms."
