CLAVATOR. 199 



Deshayes has given a good description of this species, trans- 

 lated above. One of his figures has also been copied on my 

 pi. 49, fig. 34. The specimen before me (pi. 49, figs. 32, 33) 

 is similar except that the brown lines are not waved, but are 

 nearly straight, there being only a trace of waviness in one 

 or two places. The apex is obtuse, rounded, and eroded. The 

 spiral lines are excessively weak except on the back of the 

 last whorl, where they noticeably cut the rib-strias (fig. 32), 

 which while very close and regular on the spire, are more 

 or less obsolete on the last part and base of the last whorl. 

 The lip is thin and simple. Length 52, diam. 16.5 mm.; 

 length of aperture 16.7 mm. Whorls 9^. 



Pfeiffer and Crosse and Fischer have figured much larger, 

 broader specimens. One of the figures of the latter authors 

 is copied, pi. 49, fig. 36. 



5. C. HUMBLOTI ('Ancey' Mabille). 



Shell large, imperforate, long and tapering, rather solid, 

 covered with a brown-buff cuticle, which below is narrowly 

 transversely many-banded with brown; under the cuticle it 

 is white and rather shining. The spire regularly tapers to the 

 apex, is long and obtuse. Whorls 9 ? (the upper broken), 

 regularly increasing, a little 'convex, separated by a moderate 

 suture which at the last whorl is minutely and lightly sub- 

 crenulate; grooved by close longitudinal growth stris9, which 

 on the last 5 whorls are decussate with more spaced spiral 

 impressed lines ; the last whorl elongate, tapering downwards. 

 Aperture somewhat oblique, slightly receding at base, irregu- 

 larly oblong-tapering, angular above, broad below, bluish in- 

 side. Columella angularly produced in front, twisted, sub- 

 plicate, rather thick. Peristome obtuse, dilated and adnate 

 above the columella, the margins distant, joined by a glossy 

 callous, especially conspicuous at the base (Ancey). 



Length 95, diam. 27.5, alt. apert. 31 mm. (Anc.). 



Length 80, diam. 27, alt. apert. 29 mm. (Mabille).
