c. upper Surface transversely plicate or ribbed. 



224. Macrochlamys ? peringundensis, Bedd. P. Z. S. 1891, p. 313, 



pi. 29, tio-s. 13, 14. 



Shell minutely and subobtectly perforate, depressed, sublen- 

 ticular, thin, translucent, polished, greenish horny, rather irregu- 

 larly and obliquely plicateiy striated above, smooth beneath, very 

 minutely (microscopically) sculptured longitudinally above and 

 below with fine, close, papillose, irregular lines ; spire low, 

 conoidal, the height above the periphery less than that below, 

 suture scarcely impressed; whorls 6|, flattened above, the last 

 broader, sharply angulate at the periphery, swollen below ; aper- 

 ture oblique, augulately lunate ; pei'istoine thin, straight, columellar 

 margin curved, vertical and reflected above. 



Major diam. 16, min. 13|, height 8 mm. 



Hab. Peringunda Hill, Anaimalais, 5000'. 



Apparently an ally of 31. pnUcifera, with similar microscopical 

 sculpture, but distinguished by the plications not passing over the 

 periphery and by other characters. Animal not known. 



d. SJiells not exceeding about 6 mm. (^ inch) in diameter. 

 (Generic affinities doubtf id.) 



» a. Depressed, or conoidly depressed. 



b. Smooth. 



225. Macrochlamys? perfucata, Bs. (Helix) A.M.N. H. (2) xii, 



1853, p. 93; Pfr. (Helix) Mon. Hel. iv, 1859, p. 50. 



" Shell scarcely perforate, depressed, translucent, purplish 

 brown, highly polished ; spire slightly raised, suture submar- 

 ginate, apex obtuse ; whorls 4, rather convex, closely wound, the 

 last rounded, convex beneath ; aperture lunate, scarcely oblique ; 

 peristome straight, sharp, columellar margin vertical, gently 

 reflected ; umbilicus not pervious. 



"Major diam. 5, min. 3, axis 3 mm." {Benson in Latin.) 



Hab. in the district of Galle, Ceylon {Layard). 



I do not think the Microcystina from Bintenne and Matale 

 (1800-2000'), north of the mountain complex in South-western 

 Ceylon, can be the same as this species from Galle on the south 

 coast, although referred to it by Godwin-Austen (Mol. Ind. ii, 

 p. 110, pi. 92, fig. 4). It is quite possible that Benson's type, now 

 no longer available, may have been immature, but the diiferences, 

 especially in the character of the aperture, are too great to be 

 attributed to age alone.
