MACJ10CHLAMYS. 135 



peristome thin, straight, columellar margin curved, vertical above 

 and expanded, narrowly reflected. 



Major diam. 7|, rniu. 6|, height 5 mm. 



Hob. Ceylon. 



The above description is taken from the typical specimens in 

 the British Museum, but they differ somewhat in colour and in 

 the shape of the mouth from Pfeiffer's original description. He 

 described the shell as purplish brown, and the aperture as broadly 

 lunate.

Shell very narrowly umbilicated, depressed, thin, smooth, glassy, 

 yellowish to fulvous horny, with very fine indistinct spiral 

 striation only visible when highly magnified ; spire low, conoidal, 

 apex rather prominent, suture well impressed ; whorls 6, convex, 

 increasing slowly, the last scarcely broader, bluntly subangulate 

 at periphery, flatly convex below ; aperture oblique, broadly 

 lunate; peristome thin, basal margin slightly arcuate, columellar 

 curved, oblique, not reflected over the umbilicus, but carried for- 

 ward for a short distance. 



Major diarn. 12, min. 11, height 5| mm.

 Hills, Arcot ( W. T. B.) ; Myhendra, Travancore (Beddome). 



A common species in the Carnatic and, apparently, in Ceylon. 

 Nevill has shown that the true Helix semif usca of Deshayes, 

 supposed to have been brought from Pondicherry, really came 

 from Mauritius. At the same time the shell described by Pfeifter 

 is different from woodiana, as Nevill shows. The types of 

 H. woodiana and H. carneola in the British Museum appear to me 

 identical. 



218. Macrochlamys ? rutila, Elf. P. Z. S. 1904, ii. p. 443, pi. 25, fig. 11 . 



Shell perforate, depressed, glassy, polished, closely, minutely 

 and regularly striated longitudinally (spirally) under the micro- 

 scope above and below, light chestnut ; spire very low, suture 

 slightly impressed ; whorls 6, convex, the last broader, rounded at 

 the periphery, convex beneath ; aperture slightly oblique, lunate ; 

 peristome thin, upper margin slightly arcuate, basal nearly straight, 

 columellar oblique, briefly and triangularly reflected above. 



Major diam. scarcely 15, min. 13, height 6 mui.
