DIASTYLIS SCULPTA G. O. Sars. 



Diastylis sculpta G. 0. Sars, Oefvers. Kgl. Vet. Akad. Forh., vol. 28, 1871, 

 p. 71; Kgl. Svenska Vet. Akad. Haiidl., vol. 9, No. 13, 1871, p. 24, pla. 

 1-9, figs. 1-49.— S. 1. Smith, Trans. Conn. Acad., vol. 5, 1879, p. 111. 



Although some specimens of tliis species have the areas between 

 the ridges of the carapace less deeply hollowed than in the typical 

 form as figured by Sars, there is no difficulty in distinguishing, 

 almost at a glance, between this species and D. polita. 



I have not identified any adult males among the material sent to me. 



The known range of this species is from the Gulf of St. Lawrence 

 to off Long Island and from the surface to 190 fathoms. The locali- 

 ties of the specimens that I have examined all fall within these limits.
