 twenty miles south of Halifax!, 190 fathoms, gravel and pebbles,

Upon the coast of northern New England, this is by far the most 

 abundant species of the genus. It is undoubtedly the species which 

 Stimpson called Cuma hispinosa, but his description is wholly insuflS- 

 cient to characterize the species and I therefore prefer to retain the 

 more appropriate name proposed by G. O. Sars, who has described 

 and figured the species most admirably. Professor Sars has identified 

 specimens which I have sent to him from different localities on the 

 New England coast. 



Diastylis bicornis Bate, is a very different species, of w^hich I have 

 examined European specimens, but which I have never seen upon the 

 American coast. 



Diastylis abbreviatus G. o. Sars. 



Diastylis abhreviata G. 0. Sars, (Efversight Kongl. Vetenskaps-Akad. Forhandlin- 

 gar, Stockholm, 1871, p. 74; Kongl. Svenska Vetenskaps-Akad. Handlingar, ix, 

 no. 13, p. 30, pi. 12, figs. 62-64, 1871. 



Very rare in 30 to 35 fathoms, off the coast of New Jersey, north 

 latitude 39° 54', west longitude 73° 15' (Josephine Expedition, Sars). 

 Off Cape Ann!, 35 fathoms, sand, 1878, — one specimen among great 

 numbers of Z>. quadrispinosus. Casco Bay!, 1873 : 17 fathoms, mud ; 

 also at one other station. 



This very pretty species appears to be rare.
