I found this species common on the limestone hill near Damo- 

 tha together with Diplommatina carneola, and others. It is mostly 

 allied to the Khasi hill species 67. sarrita, Bens., but is more globose 

 and a little more numerously spirally ribbed. It also appears to be 

 closely allied to Benson's G. Rawesiana (Ann and Mag. N. H., 3rd 

 ser., vol. vi, p. 193), but on comparing the description of the 

 former it seems unjustifiable to identify both. Benson says : " con- 

 fertim spiraliter striata ;" this could hardly apply to the rather 

 strong and by no means very numerous spiral ribs of liratula. Far- 

 ther Benson says a apice obtuso ;" he could hardly have overlooked 

 the mamillate form of the first smooth whorl of liratula, forming 

 the apex. I never observed in the last species, four complete 

 whorls which Raivesiana is said to possess. 



The measurements of both very nearly agree, but Rawesiana 

 would seem to be a more slender shell. Benson gives the height 

 of his shell as 2, and the diam. (largest of course) as 1*5 m.m. ; 

 in specimens of liratula with a height of 2 m m. the greatest diam. 

 never appears to be below 1*6, generally a little more. There is 

 also no perceptible impression at the umbilical region in liratula. 

 In other respects both species appear fairly to agree.
