2. Buccinum Anylicdnum. English Buccine. 



Shell oblongo-conical, thin; with the last turn somewhat 

 ventricose, depressed toward the upper margin ; the other turns 

 little convex below, and less concave above ; the suture distinct ; 

 the upper margin of the turns rather thick, and irregularly 

 plicato-riodulose ; the turns transversely obsoletely ribbed 

 and striate, and longitudinally striate ; three of the striae on 

 the last turn larger, more prominent and subnodulose, one of 

 them a little more prominent than the rest ; the mouth ovate, 

 with the outer lip thin ; the notch distinct ; the columella with 

 an oblique spiral groove ; the colour white, tinged with reddish 

 in three obsolete longitudinal bands. Length an inch and a- 

 half, breadth nine-twelfths. 



This description is taken from a specimen, dead and worn, 

 with the epidermis abraded, found by Mr. A. Davidson, at the 

 Cove, in the Winter of 1841.

3. Biiccinum breve. Short Buccine. 



Shell ovato-conical, ventricose ; with five convex whorls, of 

 which the upper three are smooth and glossy, the rest trans- 

 versely ribbed and longitudinally sulcato- striate ; the apex 

 obtuse ; the suture distinct ; the aperture about half the length 

 of the shell, ovate, the pillar twisted, the outer lip plain and 

 thin, the notch oblique ; the colour whitish, with two reddish- 

 brown bands on the last whorl, but varying to chestnut- 

 brown. 



It greatly resembles the young of Nassa incrassata ; but differs 

 in having the ribs more numerous, in being thinner and more 

 transparent, and in having the mouth larger, and its notch 

 wider, than the shell of the fry of that species. 



Not uncommon in shell sand on the beach between the Dee 

 and the Ythan, where I found it in April, 1842.
