the animal in the Land Mollusca shown by certain evolutionary 

 stages in some genera of the Zonitidae," I again referred to Crypto- 

 girasiUy and gave a figure of the animal and its shell/ 



There are so many points of resemblance between this Naga 

 mollusc and Minyongia kempi, that I feel very confident the 

 former belongs to the same subfamily, the Durgellinae. This 

 would remove Cryptogirasia rubra far from the position given it 

 by Cockerell. It has no relationship whatever to Girasia, and his 

 genus cannot therefore be retained. Until the Naga slug C. rubra 

 is collected again and examined thoroughly, it may safely be placed 

 in Minyongia with a query, only some 200 miles separating the 

 respective habitats.
