thickening of the epidermis around the peristome, which I con- 

 sider characteristic o the full-grown shell. C. austeni would 

 appear to be rare at the locality, since only five specimens were 

 found among a large number of the following species. It is 

 possible, however, that it may have been overlooked, owing to its 

 smallness." (H. F. Blanford.) 



Both this species and C. lineatum were found together by 

 Lieut.-Col. Godwin-Austen, adhering to plants in a dried-up 

 lake.

A specimen, presented in 1909 by the late W. T. Blanford to 

 the British Museum, is from the original locality, but as it only 

 measures 3 x 0'75 mm. it cannot be the type. The same remark 

 applies to a shell in the Godwin-Austen collection (British 

 Museum), which, although labelled type, only measures 3 mm. in 

 length. A second shell, which only attains 2'4 mm. in length, is 

 provided with an epiphragm, a fact which confirms my surmise 

 that Camptoceras is a genus of land mollusca.
