" It is not with entire confidence that (not having seen the 

 aTiimal) I attribute this species to the genus Camptoceras, since 

 it differs from the typical species in having the whorls contiguous, 

 except behind the peristome. In most specimens that I have 

 examined, little more than the peristome is free, but in one or

two, at least a quarter of tlie last whorl is not in contact ^^•ith the 

 penultimate whorl, as may be seen if the shell be held up to the 

 light or over a sheet of white paper in a proper position. The 

 character of the peristome and of the shell surface closely 

 resemble those of the more typical species of Campttoceras, and 

 that the habits of the animal are similar may be inferred from its 

 association with the preceding species [C. cmsteni']. As far as can 

 be judged, therefore, the evidence is prepoiidei\int in favour of 

 this generic alliance I have adopted. Perhaps it may not be 

 irrelevant to add that no species of Physa has yet been discovered 

 in India " {H. F. BUnford.)

 collection (British Museum), are marked " type." One of these 

 shows the remains of an epiphragm. Three other shells only
