height, more gently convex towards the suture. Surface with fine striae 

 which curve backwards from the suture downwards, crossed by fine revol- 

 ving lines barely invisible on the upper side of the whorl but very distinct 

 near the umbilicus. The latter not visible in the specimens examined, but 

 probably very small. Apical angle 65° ; height 5 lines ; width of body 

 whorl 4 lines ; height of the same 4 lines. Difiers from Q. eancellata, 

 Hall, in being more ventricose in the Lower half of the whorls. The Jum- 

 pers ; Div. 4, A. G. J. Richardson. 



C. HUMILIS, n sp. — Shell small with a large oblique body whorl, which 

 constitutes nearly the whole bulk ; the apical whorl minute ; whorls 

 ventricose, most convex towards the base. Surface with fine transverse 

 and revolving striae. Height about five lines ; width of body Avhorl from 

 the outer lip through to the opposite side six lines. Resembles (7. obso- 

 leta, Hall, but is distinctly cancellated. The Jumpers ; Div. 4, A. G. 

 J. Richardson. 



C. MEDiocRis, n. sp. — Shell small, consisting of four rather slender and 

 uniformly ventricose whorls ; the apical three of which are very small, but 

 considerably elevated. Surface of the cast of the interior with oblique 

 obscure undulations ; surface of shell unknown. Height six lines ; 

 width from the outer lip through to the opposite side six lines ; diam- 

 eter of the aperture, which is nearly circular, three lines. There 

 appears to be a small umbihcus in this species almost half a line wide. It 

 was collected four miles west of South-west Point ; Div. 3, A. G. J. 

 Richardson. 



C. DECORA, n. sp. — Shell conical, consisting of about four uniformly 

 ventricose whorls ; umbihcus one-fifth the whole width ; aperture nearly 

 circular. Surface covered with strong revolving striae, of which there 

 are four or five in the width of one line ; height about 8 lines, width 

 7i hnes ; diameter of the aperture four lines. This species resembles 

 the last, but difiers in having the upper whorls proportionately larger. 

 It seems probable also, that the striae, on account of their strength, 

 would be visible on the cast of the interior, but none can be made out on 

 the specimen on which C. mediocris is founded. South-west Point ; Div. 

 4, A. G. J. Richardson.
