. In the general shape and character of markings, as well 

 as in the sculpture of the spire, C. vestita has much in com- 

 mon with C. semidecussata. The first whorl is nearly smooth ; 

 several following whorls are decussate-granulate ; but the last 

 two whorls are finely and sharply costulate-striate, the 



Jcostulae bearing recurved cuticular scale-like processes 



'(fig. 49). The columella is compressed and sinuous, with a 

 sort of " siphonal funicle " near the base. A somewhat 



.similar structure may be seen in C. granulata. Length 68, 



'diam. 31, aperture 35 mm.

; Shell thin, transparent, obtuse, marked with oblique striae, 

 very strong on tbe last whorl, finer towards the summit of the 

 spire where they a*e decussated by spirals, which are also in- 

 . conspicuous. Last two or three whorls are covered with a 

 deep fulvous cuticle, paler towards the apex as well as to- 

 wards the umbilical region. Spire composed of 7 convex 

 t whorls, the suture noticeably sinuous, the last whorl semi- 

 globose, marked with large and long irregular streaks of a 

 dark brown color, and not reaching to the ends of the 

 whorl. Sometimes these streaks are quite oblique and dis- 

 appear towards the summit of the spire. Aperture oval, the 

 rperistome very thin, violaceous white inside, but yellowish 

 by transparence, showing the external spots. Columella 

 .'whitish. Length 72, diam. 32 mm. Habitat, Brazil (Bonnet) .

 ' Seems to be exactly similar to C. vestita except in the small 

 apex shown in Bonnet's figure. This may perhaps be an 

 terror on the part of the draughtsman. Figure and descrip- 

 tion from Bonnet.
