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

 th- 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 

 •ipplies to a shell in the Godwin-Austen collection (British 

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

 ienoth A second shell, which only attains l>-4 mm. m length, is 

 provided with an epiphragm, a fact which confirms my surmise 

 that Camptoceras is a genus of land mollusca.
