459. Prevosti, Son-erhi/ (f. 66-i). — 0. testa elongato- 

 cylindracea, albicla, aurantio obscure fasciata, lineis numerosis 

 minutis aurantiacis irregulariter undulatis et angulatis scripta ; 

 spira elata, gradata ; aufractus concaviusculi, striis duobus 

 spiraliter sculpti, ultiraus supra obtuse angulatus, infra 

 angulum couvexiusculus, laevis, basi parum attenuatus, sul- 

 catus ; apertura mediocriter lata, basin versus aliquanto latior, 

 fauce lutea. Long. 40, lat. 10 mill. 



In describing this species in the Proceedings of the 

 Zoological Society I stated that one specimen was in the col- 

 lection of Dr. Prevost, and another in that of M. Thomas. 

 This was a mistake, both specimens belonging to the latter 

 collection. They are, I believe, the only specimens known 

 of the species. It is a shell of very distinct and peculiar 

 character.

460. ARTICULATUS, SoiverJ))/ (f. 667). — C. testa snb- 

 pyriformi, polita, castanea, lineis nigrescentibus tenuissimis 

 spiralibus albo minutissime punctatis quasi articulatis, ad 

 angulum spiralem et infra medium f'asciis duabus albis 

 concinne fusco maculatis ornata ; spira acute conica ; apice 

 roseo ; anfractus concavo-declives, ultimus supra subacute 

 angulatus, basi attenuatus, distanter sulcatus ; apertura fusco- 

 purpurea. Long. 18, maj. lat. 10 mill. 



The specimen figured is rather more contracted in the 

 middle than others I have seen. The finely articulated lines 

 are sometimes almost hidden by the dark chestnut colour of 

 the surface. 



Hab. Mauritius. 



461. TEGULATUS, Sowerlnj {?. 665). — C. testa elongato-tur- 

 binata, distanter et fequaliter sulcata, inter sulcos planilirata, 

 super sulcos maculis nigro-fuscis linearibus longitudinaliter 

 flammulata, sulcis concentrice sculptis ; spira concavo-acumin- 

 ata, angulo acuto ; anfractus spiraliter striati, et concentrice 

 cancellati. Long. 22, maj. lat. 10 mill. 



The dark-brown spots, arranged in longitudinal flames, 

 and thickened in two spiral bands, give a tesselated appear- 

 ance to this pretty little sulcated shell. 



Hab. China Sea.

 utrinque acuminata, fumeo-fuscata, laevigata, antice distanter
