OF CONCHOLOGY. 77 



A specimen of this species was received from Peru, through 

 Mr. Cuming, labelled strigata, Brod. 



Discinisca Cumingii ! Brod., P. Z. S. 1833, p. 124. Reeve, 

 Conch. Icon. PI. i, f. 6, 1862,= D. strigata, Brod. fide

Cape St. Lucas to Panama. 



Mr. Reeve's figures afford no characters by which this might 

 be distinguished from the last species. The specimens received 

 under this name from Mus. Cuming cannot be distinguished from 

 D. stella, Gould, by constant characters.

Cuba, Martinique, Cuming. 



I have never seen this species which is stated by Reeve to re- 

 semble D. Stella. It has relations with D. Cumingii, and a 

 series should be compared. 



Discina ( ? Discinisca) atlantica, Jeffreys, MSS. 



North east Atlantic. 



I am indebted to Mr. Jeffreys for information in regard to 

 this species, which is on the point of publication in the Proceed- 

 ings of the Zoological Society of London.

The internal laminae support the posterior retractor (adjustor 

 of Hancock) muscles, not the post-parietals as suggested previ- 

 ously.

Shell imperforate ; texture moderately solid but contracting 

 about the edges in drying ; very narrow and elongated, rather 

 square in front. Beaks sharply acuminated, valves in the natu-
