pallial tube extends further than in P. carlnata. Sars pro- 

 loosed for the present species the generic name of Typliloman- 

 gelia, on account of its being eyeless. But Eulima stenostoma 

 is another instance of blindness among species usually provided 

 with organs of -sight. 



P. 390. — A fresh but dead specimen of P. galerita, Ph. (P. 

 (jcderitmn, Moll. Sic. ii. p. 172, t. xxvi. f. 15) was dredged by 

 Carpenter and Thomson in 189 f., about 50 miles N. of the 

 Butt of the Lewis. It is a very rare Calabrian fossil. See 

 pi. cii. f. 6.
