 (Blanford.) 



Hob. Burma: Nattouug near Moulmain (Theobald)- Attaran 

 Valley (Hungerford). 



" It is more ovate than C. Philippiana and C. vespa, smaller 

 and less tumid than C. bulbus." (Blanford.) 



In addition to the differentiating characters alluded to by 

 Blanford, C. ovata has a shorter spire which increases more 

 suddenly than in phiUppiana, the whorls are less tumid, and it 

 possesses fine spirals, which are lacking in its ally. There are 

 some shells in the British Museum from Pathingtoun, Attaran 

 Valley, measuring 18 x 6-75 mm., others from Nattoung, the type 

 locality, and Moulmain have the spire still more convex, the 

 former having a diameter of 7 mm. with a length of 17'75 mm., 

 and the latter being 18x8 mm. The shell figured by Hanley is 

 also in the National collection, having been presented by 

 Mr. Harvey ; it measures 18x7 mm.
