 HIDALGO, Obras Malacol. i, p. 158, t. 25, f. 1-3. 



The color-mutations recorded by Hidalgo are as follows : 



1. (Typical). Whitish, with a chestnut sutural line and a buff 

 band above the periphery (figs. 23, 24.) 



2. Unicolored, white. 



3. Pale straw-colored, with a narrow white peripheral band, nar- 

 rowly bordered above and below with green, (fig. 25.) 



" The second and third varieties have much similarity to C. hanleyi 

 and its variety bifasciata Lea, but they have the aperture more 

 produced transversely, the peristome narrower, and the last whorl 

 more inflated, around the basal margin of the peristome, as it is in 

 typical benguetensis, of which I, therefore, consider them varieties." 

 (Hidalgo.) 

 C. GEOTROCHUS Mollendorff. 



Imperforate, trochiform, delicately obliquely striatulate and 

 decussated with close spiral lines; chestnut-brown with a whitish 

 band at the carina and another below the narrow brown subsutural 

 zone ; spire subregularly conical, apex obtuse, whitish. Whorl 4fc, 

 nearly flat, the last acutely white-carinated, shortly deflexed in front, 

 swollen toward the aperture beneath, having a pale yellowish band 

 around the columella. Aperture very oblique, angulate-elliptical ; 

 peristome expanded, albolabiate ; columella excavated, oblique.

Chlorcea geotrochus v. MOLL., Nachrichtsbl. D. M. Ges. 1888, p. 

 89. 



This species has much the aspect of Papuina cleryi. It is closely 

 allied to C. hanleyi and C. benguetensis. 

 C. ANTONII Semper. PI. 21, figs. 34, 35. 



Imperforate, globose, shining, spirally very minutely striated, pale 

 green or straw colored, having two reddish lines above, sometimes 

 ornamented with a brown band below; spire elevated; suture 

 smooth ; whorls 4, convex, the last deflexed in front ; columella 

 short; aperture lunate-rounded; peristome simple, subexpanded, 

 margins conniving.
