pletely covers the umbilicus, and by its calcareous opercu- 

 lum. 



P. 231. — Adeorbis subcarinatus. Herm, a live specimen 

 under a stone between tide-marks, with. Rissoa striatula (Mar- 

 shall) ! He noticed that the animal was very large in propor- 

 tion to the shell, and so red that it seemed to stain his fingers. 

 Philippi describes the animal of his Solarium luteum, even 

 when dead, as " coccineum." The operculum of Mr. Marshall's 

 specimen agrees with my description. F. Selsea and Port- 

 rush (A. Bell) ! E. Med. and Adr. ! Delphinula pusilla, 

 Calcara. 



P. 235. — Lamellaria perspicua. F. Monte Mario (Conti). 

 E. Labrador, 15 f. (Packard). Var. lata : — 



Body whitish : mantle closely and minutely tessellated, with 

 milk-white lines of division ; it is not pustulated : pallial 

 sinus or notch narrow and deep : tentacles awl-shaped : eyes 

 black : foot lanceolate, truncated and double-edged in front, 

 with short angular corners, bluntly pointed behind. 



L. iirodita of Loven probably inhabits the coast of Shetland 

 as well as that of Scandinavia. Last summer (1868) I dredged 

 in 110 f. off Unst a Lamellaria of an unusually large size, 

 more than an inch long ; but unfortunately it was handled too 

 roughly, and the shell was broken to pieces. According to 

 Loven, the mantle in this species is depressed, with the notch 

 somewhat to the left ; the shell is elongated and opaque, ex- 

 hibiting coarse lines of growth ; and the spire is minute, 

 occupying only -t of the shell.
