t. 16. f. 1. 

 Schroeter Erdconch. t. 1. f. 3. 

 Inhabits rivers, ponds, and ditches ; not uncommon in any part 



of Europe. 

 Shell about an inch long, and three-quarters of an inch broad, 

 rather pellucid, thin, brittle, and of a pale yellow or horn- 

 colour ; it has four whirls, of which the body-whirl consti- 

 tutes almost the whole shell, and ends abruptly in a small 

 and depressed, but well-defined spire ; the aperture is oval, 

 and in a large specimen is three-quarters of an inch long, and 

 half an inch wide. 



sicuLA. 184. Shell ovate, smooth, whitish, with the 

 apex acute, and the pillar one-plaited. 



Helix teres. Gmelin, p. 3667. ? 



Bulimus Siculus. Bruguiere Enc. Meth. p. 3S5. 



Gualter, t. 5. f. NN. Schroeter Flussconch. t. 10 A. f. 7. 



Inhabits fresh water in Sicily. Bruguiere. 



Gmelin's H. teres is derived wholly from Gualter, of whose 

 figure Schroeter's is a copy, and it is quoted with a mark of 

 doubt by Bruguiere for his B. Siculus, who says he receiv- 

 ed it as a fresh-water shell from Sicily; Bruguiere has de- 

 scribed it to be eight lines and a half long, by four and two 

 thirds broad, with five whirls, of which the body-whirl is 

 proportionably very large, and the last so small as to be al- 

 most imperceptible ; to the naked eye it is smooth, but when 

 magnified appears to be minutely striated transversely ; it is 

 yellowish white, and is thicker than H. auricularia, which 

 Bruguiere says it somewhat resembles. 



GLUTINOSA. 185. Shell ventricose, extremely fragile 

 and pellucid, with a short obtuse spire ; aper- 

 ture very large. 



Helix glutinosa. Gmelin, p. 3659. Montagu Test. p. 379.
