C. CALYPSO Broderip. PI. 12, fig. 3. 



Imperforate, ovate-pyramidal, very minutely striated ; diapha- 

 nous ; buff-white, ornamented with greenish bands and a chestnut 

 basal area. Spire pyramidal, apex obtuse, purple-brown. Whorls 

 6, rather flat, the last a little shorter than the spire, subangular in 

 the middle. Columella thickened, somewhat twisted, flesh colored. 

 Aperture lunate-oval, milk-white within ; peristome narrowly 

 expanded, edged with chestnut. (P/V.) 



Alt. 40, diam. 21 ; aperture, alt. 21, breadth 13 mill. 



Negros, Philippines.

 Seems to be closely allied to C. caluta. 



C. CAMELOPAPvDALis Broderip. PI. 12, figs. 4, 5. 



Imperforate, elongated, turrited. Light brownish-yellow, becom- 

 ing browner below, the earlier (embryonic) 2 whorls orange-brown ; 

 the remaining whorls have longitudinal stripes of cream-white cuti- 

 cle. Spire long, apex obtuse; whorls 7 to 7-}, the earlier 2 quite 

 convex, the rest nearly flat ; body-whorl obviously or almost im- 

 perceptibly subcarinated. Aperture narrow, elliptical, white inside, 

 the lip expanded, dark brown. Columella visibly twisted, brownish 

 or fleshy-white, surrounded by a purplish callus. 



Alt. 51, diam. 22 ; oblique alt. of aperture 21 mill. 



Alt. 49, diam. 22 ; oblique alt. of aperture 22 mill.

The extremely slender form and the style of marking (the stripes 

 being mainly longitudinal and neither zigzagged nor oblique except 

 on the base) constitute the principal characters of this form. 

 Neither of these characters is of much value, the alleged differences 

 in contour between camelopardalis and boholensis being readily 

 bridged by many specimens before me.
