Fam. Bulimin^. 



24:.~Phengus intermedins, Pfr. 



Bulimus (Beddomea) intermedius, Pfr. 



This species, as figured in Conchologia Indica (pi. xxi., 



figs. 6-8), is somewhat common in Ambagamuwa. Dr. 



Jousseaume has remarked that the figures given in the 



Conchologia Indica appear to belong to two different species 



(Proc. Zool. France, 1894, p. 295). In reality, however, they 



are identical, the species being very variable in size and 



contour. The shells have a beautiful glossy appearance as 



a rule, but I have taken specimens (alive) with the enamel 



entirely worn away. The animal is of a rich emerald green, 



with yellow tentacles and foot. It is visible through the 



semi-transparent shell. 



Habitat amongst foliage in forest, 3,000 to 4,000 ft. It 



is sometimes found feeding on coffee and tea plants. 



Obs. — G. Nevill, writing in 1881, after the publication of 



the Conchologia Indica, mentions this species as follows : — 



Sub-genus Beddomea, G. Nevill. 



(Hand list, 1878, p. 127, type Bui. ceylanicus, Pfr.) » 



The animal of the type species of this very distinct and well-marked 

 group was described by E. L. Layard {Annual .Magazine, 1853) as of 

 a brilliant green colour, visible through the shell ; it feeds on the 

 coffee plant. (-/. A. S., Bengal, No. III., p. 134.) 



This description is true of B. intermedius but not of B. 

 ceylanicus (see Conchologia Indica, pi. xxi., fig. 2 ; and pi. 

 cxlviii., fig. 9). The latter is a low-country species, having 

 a much thicker shell with brilliantly coloured markings, 

 while B. intermedius is always white. 



25. — Phengus Simoni, Jouss. 

 This species is not so common as the last. It is, as Dr. 

 Jousseaume has pointed out, distinct from B. albizonatus of 

 Reeve, by its smaller size and by the absence of the white 

 band at the angle of the shell. It is, moreover, much less 

 sharply keeled, and the shell is thicker and more blue in 

 colour. Habitat in forest, on the leaves of trees.
