COCHLICOPA, 287 



very different, and is more like C. papillaris or the Heliw 

 bidens of Linne. C. solida has been found by Bouchard- 

 Chantereaux near Boulogne, and may therefore be dis- 

 covered in this country. Possibly this may have been 

 Pulteney^s species, which was said to be found in Dorset- 

 shire and has been referred to C. papillai^is. The last- 

 named species has been recorded by Nilsson as Swedish. 

 It is very common in the South of France and in Italy. 



Genus X. COCHLI'COPA*, Ferussac. 

 PL VII. f. 15, 16, 17. 



Body rather long, gelatinous and lustrous, always contain- 

 able, within the shell : tentacles 4 ; upper pair long and nearly 

 cylindrical ; lower pair short and conical : foot rather long and 

 narrow. 



Shell oblong, rather sohd, smooth, glossy and transparent : 

 epidermis resembling a coat of thin varnish : whorls rapidly 

 increasing in size, the last being much larger in proportion to 

 the others : spire long : month small, obliquely pear-shaped, 

 sometimes fui'uished with teeth and folds as in ClausUia, and 

 ha^dng the base more or less distinctly notched (especially in 

 the young): outer lip thickened by an internal rib, but not re- 

 flected, sometimes channeled at its up2)er angle : umbilicus 

 wanting in the adult. 



The position of the few European species which are 

 comprised in this genus has for a long time been de- 

 bateable ground. In 1817 Schumacher instituted the 

 genus Glandina for some species of Lamarck^s much 

 older genus Achatina, as well as for other species which 

 will be presently referred to, the type of Schumacher's 

 genus being the Bulimus glans of Bruguiere. Montfort's 

 genus Polyphemus, which had been previously founded 

 on the same type or species, was considered inadmissible, 

 l)ecause that name had been appropriated to a genus of 



* Having a notch in the slicll.
