MACROCHLAMYS. 137 



Hob. On the plateau of the Mlgiris, 6000-7000' ; Pykara, 

 Avalanche, &c. A common species. The longitudinal sculpture 

 is not easily detected. 



Hanley (Conch. Ind. p. vi, footnote 13) states that this species 

 is African, but gives no evidence. Pfeiffer in the seventh volume 

 of the Mon. Hel., published the same year (1876) as Hanley's work, 

 gives the Mlgiris as the only locality. 



222. Macrochlamys ? prava, Blf. P. Z. S. 1904, ii, p. 443, pi. 25, fig. 9. 



Shell perforate, depressed (the axis rather higher in proportion 

 to the diameter), thin, smooth, polished, with traces of close, sub- 

 obsolete, irregular, longitudinal striation visible under a microscope, 

 brownish rufescent ; spire low, conoidal, suture faintly impressed ; 

 whorls 5, convex, the last considerably broader, well rounded at 

 the periphery and rather tumid below ; aperture almost vertical,

subovately lunate, almost circular; peristome thin, straight, 

 columellar margin almost vertical, and slightly reflected above, 

 curved below. 



Major diam. 10|, min. 9, height 5J mm. 



Hal. Beypur, Malabar (W. T. .), Anaimalai Hills (Beddome\ 

 Travancore. I have also specimens from Coonoor Ghat, Mlgiri 

 Hills, apparently belonging to this form. 



This resembles the Arakanese M. kumahensis, but is slightly 

 less globose. 



223. Macrochlamys ? vilipensa, Bs. (Helix) A. M. H. H. (2) xii, 1853, 

 p. 93 j Pfr. (Helix) Mon. Hel. iv, 1859, p. 49 ; H. $ T. (Helix) 

 C. I. 1876, pi. 89, figs. 4, 5, 6. 



Shell openly and perviously perforate, depressed, translucent, 

 smooth, polished, amber- coloured or tawny ; spire slightly convex, 

 apex obtuse, suture impressed ; whorls 2, slightly convex above, 

 regularly increasing, the last rounded at the periphery, convex 

 beneath ; aperture scarcely oblique, broadly lunate ; peristome 

 thin, straight, columellar margin much curved, almost vertical 

 above and reflected. 



Major diam. 8, min. 7, height 4 mm. 



Hob. Ceylon, Mehintali Eock (Layard) ; Calcad Hills, Travan- 

 core (Beddome). 



This species resembles M. nepos, but is distinguished by narrower 

 last whorl, lower spire, and much more open perforation.
