270 HELIX-CHLORITIS. 



strongly converging, reflexed ; columellar margin short, dilated 

 above, partly closing the umbilicus. 



Alt. 12i, greater diam. 20, lesser 18 mill. (Crosse.*)

H. NORODOMIANA L. Morlet. PI. 36, figs. 35, 36, 37. 



Shell umbilicated, depressed, thin, huffish, imicolored, minutely 

 and regularly striated, subdiaphanous, apex but little projecting; 

 whorls 5$-6, a little convex, the last angulated, descending ; suture 

 profoundly impressed, subcanaliculate ; umbilicus broad, carinated ; 

 aperture oblique, base rounded, columellar margin short, dilated 

 above ; margins joined by a thin callus ; peristome white, shining, 

 reflexed. Alt. 9, greater diam. 10, lesser 7 mill. (3/or-.) 



Kamchay, Cambodia. 



H. norodomiana MOR. Journ. de Conchyl. 1883, p. 106, t. 4, f. 3. 



There is evidently an error in Morlet's measurements. The spe- 

 cies should be compared with H. tranquereyi C. & F. (Manual iv, 

 p. 64). 



H. MIARA Mabille. PL 68, fig. 83, 83. 



Shell umbilicated, depressed, the spire slightly convex ; corneous, 

 somewhat translucent, thin, light, striatulate, under a lens seen to be 

 densely and very finely granulated in every part. Peristome nar- 

 rowly expanso-reflexed all around. 



Whorls 4^-5, convex, the last one wide, a trifle descending in 

 front, not at all constricted behind the expanded peristome, which 

 is white and a little thickened within. There are traces of low folds 

 parallel with growth-striae on parts of the body-whorl. The base is 

 indistinctly, obtusely angled around the narrowly funnel-shaped um- 

 bilicus. Aperture not much oblique, terminations of peristome con- 

 verging. Alt. 10, greater diam. 20, lesser 16J mill.

This species is very similiar to H. hunger ford iana Nev. ; it con- 

 stantly differs in the more reflexed, more thickened peristome, and 

 decidedly wider umbilicus. The specimens before me were collected 

 by 1'Abbe A. Vathelet.
