170 PYRAMIDELLIDjE. 



HABITAT : Muddy sand in 12-87 f., Shetland and 

 west of Scotland; Aberdeenshire (Dawson) ; Whitburn 

 (Abbes and Howse, fide Alder) ; Berwick Bay and off 

 Coquet Island (Mennell) ; Larne, co. Antrim (Hynd- 

 man and Waller) , perhaps from a post-glacial deposit ; 

 Land's End (Hockin). Of the variety Mr. Barlee 

 dredged one specimen, and I another, in the Hebrides ; 

 it may be a distinct species. The typical form is fossil 

 at Gravina in South Italy (Scacchi), and Palermo (Phi- 

 lippi) . Taken on many parts of the Scandinavian coast 

 from Fininark to Bohuslan, in 15-200 f. (Loven and 

 others), Croisic in Brittany (Cailliaud), Madeira, in 

 18-24 f., and the Canaries, in 20 f. (M f Andrew) . 



When crawling, the animal trails its long shell hori- 

 zontally behind it. The upper portion of the spire is 

 now and then twisted a little on one side, as in species 

 of Eulima. 



I named this well-marked shell Eulima crassula, and 

 Forbes E. MacAndrei.

BODY nearly clear frosted-white, mixed with minute snowy 

 flakes : mantle having the usual small fold at the upper corner : 

 snout rather long, very broad, square in front, where it is deeply 

 notched in the middle so as to divide that part into two minute 

 roundish lobes ; it is grooved the whole length, the groove being 

 continued towards the neck, just separating the tentacles at 

 their basal centre ; at its upper surface, close to the base, is 

 the orifice for the proboscis: tentacles diverging almost at a 

 right angle, and resembling short, broad, minute leaves, each 

 marked with an opaque-white stripe or vein through the middle; 

 they bevel toafine edge,and can, with theirlarge flexible margins
