COCHLOSTYLA-ORTHOSTYLUS. 15 



oblique, close, whitish, more or less tawny. Spire conic, apex obtuse. 

 Whorls 6, slightly convex, the earlier 3 white, ante-penultimate 

 pale tawny, the rest chestnut colored, the last a little shorter than 

 the spire. Columella nearly straight, whitish-fleshy, a little cal- 

 loused. Aperture oval, obliquely subtruncate above, blue-white 

 inside ; peristome somewhat thickened, reflexed, blackish-brown. 

 (Hid.') Alt. 43, diam. 24 ; aperture, alt. 19, width 13 mill. 



Entire Island of Balabac, Philippines. 



C. graellsi HID., Journ. Conch. 1886, p. 155, t. 8, f. 5. 



This species much resembles C. satyrus Brod. and cinerosus Pfr. 

 In satyrus the cuticle is unicolored and darker, in cinerosus the 

 flarnmules are wider, more spaced, and they terminate a short dis- 

 tance from the suture. In this species there is a dark line below 

 the suture on the last two whorls. (Hid.) 



C. CINEROSA PfeifFer. PI. 1, fig. 4. 



Irnperforate, ovoid, solid, obliquely striatulate; brown, covered 

 with a dark ashen cuticle which is worn off in streaks. 



Spire convex-conic, apex obtuse. Whorls 5, moderately convex, 

 the last a little shorter than the spire. Columella subplane, slightly 

 dilated forward, white. Aperture oblique, truncate-oval, whitish 

 inside ; peristome subsimple, narrowly expanded. 



Length 361, diam. 13 mill. ; length of aperture 20, breadth 14 

 mill. (Pfr.) 



Palawan, Philippines. 



Bui cinerosus PFR., P. Z. S., 1855, p. 107, t. 32, f. 5; Monogr.iv, 

 p. 375. 



The small size, obtuse spire and streaked cuticle are prominent 

 marks of this species, but it may prove to be only a small form of 

 C. satyrus. 



C. C^SAR Pfeiffer. PL 5, fig. 1. 



Imperforate, globose-conic, thin, nearly smooth, white under a 

 deciduous tawny cuticle; spire conoid, apex obtuse; whorls 5?, 

 moderately convex, the last about equalling the spire. Columella 

 nearly vertical, flat, white, truncate-dentate. Aperture subdiagonal, 

 lunate-rounded, white inside ; peristome white, narrowly expanded, 

 the right margin dilated forward above. (Pfr.) 



Alt. 46, diam. 33 ; aperture, alt. 23, width 19 mill.
