NO. 48—1897.] CEYLON MALACOLOGY. 



15 



beautiful specimen. It has the same habitat as the last 

 species. 



Height 3*50 mm., diameter 6 mm. (largest specimen). 



11. — Macrochlamys partita, Pf r. 



This is one of our commonest species. It is rather variable 

 in size and in depth of colour. The animal, which is black 

 and white, is dimly visible through the shell. 



Habitat amongst leaf mould around the roots of plants. 



12. — M. politissima, Pfr. 



This species is fairly common throughout the district, but 

 perfect specimens are scarce on account of the brittle nature 

 of the shells. The animal, which can only partially retreat 

 into its shell, is bluish-black with dark gray tentacula. 



Habitat among thickets and scrub in ravines and swampy 

 places. 



13. — M. carneola, Pfr. 

 I have taken one specimen only of this species from among 

 ferns in a swamp (3,000 ft.). 



14. — Gorilla erronea, Albers. 



This species is fairly common throughout the district. 

 The shells are very variable in size, shape, and colouration, 

 some specimens being almost black. The animal is dirty 

 white, its dorsal surface dusted with grayish granules. 



Habitat in heavy forest among fallen leaves. 



15. — C.fryce, Gude. 

 This is very similar to the last species. Mr. Gude has 

 made a new species of it on account of a slightly different 

 arrangement of the parietal folds of the armature. (See 

 Science Gossip, 1896, vol. III., p. 89. Dr. Jousseaume calls 

 it a large variety of G. erronea, and I think he is correct.) 



16. — >G. Beddomece, Hanley. 

 This species is not common here. The shells found in 

 Ambagamuwa appear to be a good deal smaller than those 

 found at a lower elevation, where they are more plentiful.
