47.— i£. Prestoni, Godwin-Austen. 

 This species, first discovered in the Uda Pussellawa district 

 by Mr. Preston, is found in jungle and scrub throughout the 

 upper part of the district. 



48. — Lamprocystis (?) sinhila, Godwin-Austen. 

 I have not often found this species in the adult state. It 

 also occurs in Uda Pussellawa. 



Hab. — Among ferns in damp shady places. 



49. — Polita notabilis, Sykes. 

 This form is remarkable, as being the first of its genus 

 known from this region. It has hitherto been recorded 

 from Southern Europe. It is abundant on decaying leaves 

 in forest undergrowth. 



50. — Microcystina Uta, Sykes. 



Fairly abundant on the trunks of trees in wet weather. 

 It is closely allied to the Microcystina of the Andaman 

 Islands. 



51. — Thysanota eiimita, Sykes. 



This pretty little shell is fairly common in the lower part 

 of the district, 2,000 ft. Its affinities are with T. Mspida 

 and Helix biciliata of the Province of Uva. 



Hab. — Beneath fallen leaves in scrub (lantana). 



52. — Kaliella delectabilis, Sykes. 



Abundant on the trunks of orange and mango trees in 

 bungalow gardens. It is also found in Uda Pussellawa. 



53.— iT. Colletti, Sykes. 



This species is similar to the last, but is devoid of spiral 

 sculpture. 



Hab. — The same as K. delectabilis. 



The animal, which is very active, is speckled gray with 

 grayish white foot.
