NO. 51.— 1900.] CEYLON MALACOLOGY. 135 s 



41. — Macrochlamys regulata, Benson. 



This species is rather scarce, full-grown specimens being 

 seldom found perfect. 



The shells are variable in size and thickness, some being 

 quite transparent. 



Hab. — Among fallen leaves in dense scrub, 3,000 ft. 



42. — Microcystis perfucata, Bens. 



Apparently a low-country species, I have a few speci- 

 mens from the lower end of the district — kindly identified 

 by Mr. Sykes. 



Hab. — In leaf mould. Seldom seen above 2,000 ft. 



£3.—$yksia clathratula, var. compressa, Sykes. 

 I have found a few specimens of this variety in the upper 

 part of the district. 



Hab. — Beneath fallen leaves in forest, 3,600 ft. 

 The animal is pale reddish-brown. 



44. — S. caliginosa, Sykes. 

 Fairly abundant among decaying leaves in* forest. It is 

 usually found with shells of S. clathratula, from which it is 

 readily distinguished by its olive-green colour when living. 

 Height 2-10 mm., diameter 6 mm. 



45. — Euplecta Golletti, Sykes. 

 Common throughout the forest of Ambagamuwa. It is 

 frequently found feeding upon the young leaves of the 

 " Nilu " (Strobilanthes), in company with Leptopoma oro- 

 philum. 



This species is nearly related to the beautiful Helix Isabel- 

 Una of Pfeiffer. 



The animal, gray with white foot, is visible through the 

 semi-transparent shell. 



46. — E. scobinoides, Sykes. 

 Fairly abundant amongst tall grass and ferns in swamps 

 in the upper part of the district, 3,600 ft.
