2. S. e'legans^, Kisso. 



S. elegans, Eisso, Moll. Alp. Marit. p. 59, no. 128. S.putris, var., F. & H, 

 iv. p. 135, pi. cxxxi. f. 1-3. 



Body thick, yellowish-brown, sometimes nearly black, co- 

 vered with minute round tubercles and clusters of black 

 specks : tentacles very short, yellowish- white and transparent, 

 streaked down the middle with lines of black specks ; upper 

 pair rounded at their tips : snout round and somewhat tumid : 

 foot broad, rounded in front and behind, narrower at the tail. 



Shell oblong, not very thin, glossy, scarcely semitrans- 

 parent, amber-colour with a brownish or reddish hue, sculp- 

 tured like the last species : epidermis rather thin : whorls 3-4, 

 moderately convex but compressed towards the suture, the 

 last occupying about three-fourths of the shell : spire rather 

 short and pointed : suture remarkably oblique, not very deep : 

 mouth oval: outer lip slightly tliickened and considerably in- 

 flected above : pillar lip sharp. L. 0*6. B. 0-25. 



Yar. 1. minor. Shell smaller and thinner, of a reddish- 

 brown colour, with a shorter spire and more expanded mouth, 



Yar. 2. ochracea. Shell smaller and thicker, also reddish- 

 brown, with a larger spire and smaller mouth. 



Habitat : Similar situations and as extensively distri- 

 buted as >S^. /?w^m. Var, 1. Falmouth; Hammersmith 

 (J. G. J.). Var. 2. Scarborough (Bean); Newcastle 

 (Alder) ; Tenby ; Tingwall lake, Zetland (J. G. J.). The 

 last variety is often mistaken for S. oblong a. This spe- 

 cies is also one of our upper tertiary fossils. Abroad it 

 is found everywhere between Finland and Sicily. Ac- 

 cording to Deshayes, it inhabits the Morea ; and Captain 

 Hutton notices it as an Afghanistan shell. 



The present species sometimes occurs living with ;S^. 

 putris, of which, on account of the great variability of 

 form which prevails in all the species of this genus, 

 S. elegans has been considered by some authors as a 

 variety. Each of these species has, however, its own
