I am inclined to think that C. omalomphalus Adams, is only a 

 small variety of C. variegatus Adams, which is common on all the 

 South Coast, but is not seen in N. S. Wales. With this species I 

 also identify C. zebrides of the same author. Thahtia zebrides is a 

 common N. S. Wales shell which must not be confounded with it. 

 I think also that C. gibbosus Adams is a doubtful species. The 

 difference between the present species C. undatoides and C. 

 variegatus is that it is smaller, more solid, whorls more rounded, 

 umbilicus narrower, and the coloring deeper. 



Teeebea vexilia. PL 4, fig. 2, and 2a. 

 T. t. elongato-pyramidata, turritissima, nitente, luteo-albida, linea 

 pallide castanea zonata, apice acutissimo, livido,* translucente ; anfr. 

 20, parum convexis, adsuturam constrictis, irregulariter crebre costatis 

 super ne conspicue sulcatis, infra regular iter 4 — 5 striis insignitis ; 

 costis obtuse angulatis, (ult. anfr. 20, circiterj lineis incrementi 

 aliqicando confusis ; apertura ovata, postice coarctata, antice eccpansa; 

 labro tenui, labio rejlexo, crasso ; canali contorto brevi, corrugato, 

 marginato ; sutura canaliculata. Long. 42, lat. 7£. 



Shell elongately pyramidal, turretted , shining, yellowish white 

 zoned with a pale-chesnut line; apex very acute, livid, translu- 

 cent ; whorls 20, flattened, constricted at the suture, closely and 

 irregularly ribbed, conspicuously grooved a little above the middle, 

 and below spirally striate with 4 to 5 rather deep, distinct lines. 

 Eibs obtusely angular, about 20 in the last whorls, sometimes 

 confused with the lines of growth. Aperture ovate, narrowed 

 above and expanded anteriorly. Labrum thin, simple ; lip reflexed 

 thick; canal short, twisted, corrugated and margined; suture 

 channelled. 



I have figured by the side of this species a back and front view 

 of T. Brazieri, Angas. The differences are that the latter is much 

 smaller, has much less distinct ribs, no medium sulcus, no spiral 

 stride, the whorls are faintly coronate, the suture not so well 

 impressed and the color is a more decided yellow with the ribs a 

 pronounced reddish chesnut.
