98 COCHLOSTYLA-CHLOR^A. 



Chlorcea antonii SEMPER, Reis. Phil., Landmoll. iii, p. 228, t. 10, 

 f. lOa, b. H. (Chlorcea') hugeli HIDALGO, Obras Malacol. i, p. 160. 



This species I have not seen. It appears to be more globose, with 

 narrower lip and less oblique aperture than C. hugeli Pfr. 



C. AMCENA Pfeiffer. PL 21, figs. 21, 22. 



Imperforate, depressed-globose, solid ; white, having a broad purple- 

 black zone above the periphery and ascending the spire. Apex and 

 lip white ; last whorl abruptly and deeply deflexed in front; not 

 carinated, often obscurely angled just above the upper insertion of 

 the lip. 



Spire convex, apex obtuse ; whorls 4?, the last abruptly descend- 

 ing in front, slightly constricted behind the lip. Surface lightly 

 obliquely striatulate and microscopically, spirally striated. Aperture 

 very oblique, oval-truncate, showing the band within; peristome 

 narrowly thickened and reflexed, the baso-columellar margin adnate, 

 straightened, thickened within. Alt. 12, greater diam. 16 mill. 



Luzon, Philippines.

 20 ; Monogr. i, p. 270. H. hugeli var. REEVE, Conch. Icon., f. 136a. 



A solid, subglobose species, allied to C. hugeli, but not distinctly 

 carinated and differently colored. It is much smaller than C. 

 paradoxa, restricta or undina. 



C. STRENA Beck. PL 21, figs. ^5-20. 



Imperforate, globose-depressed, thin but solid, the periphery 

 rounded except just in front of the aperture where it is carinated; 

 sometimes uniform straw-yellow with white apex, but usually pale 

 cream-white or pale green with the apical whorl pink, the body- 

 whorl encircled with one or two green or greenish-purple zones, 

 visible as vivid brown bands within the aperture, the upper band 

 ascending the spire above the suture, and becoming brown there, 

 and the peristome dark brown. Spire low, convex; suture super- 

 ficial ; whorls 4, the last descending rather abruptly in front. Aper- 

 ture oblique, wide-lunar ; peristome scarcely expanded above, outer 

 and basal margins narrowly expanded, columellar margin adnate. 



Alt. 14, diam. 22 mill.
