 .■^liell convolute, ovate, thin, generally liovny, with spire 



eoncealed ; inner lip very thin, with columella c\irved ; 



outer lip elevated above the spire. 

 It would be difficult to name a genus of shells consist- 

 ing of so few known species being found living in so many 

 Mud such distant parts of the world. The thirty-two 

 "pecies described in this Monograph range from Great 

 Britain in the north to Australia in the south, from eastern 

 k) western seas. South Africa, North America, India, 

 I 'liina, Borneo, and the Philippines, all contribute their 

 i)ue or more species, the known number of which must be 

 increased as the numerous localities come to be explored. 

 Till' jliells of Iliiiiiiiieu and Bidla dift'er principally in the 

 lioniy ti.xlure of the former, as compared to the poreella- 

 nroiw structure of the latter; but the animals differ very 

 H iilrly in many respects.
