MOLLUSCA. 65 



Coppiriger at Port Jackson are like fig. 59 in the Conch. Icon. (C. car- 

 bonarium. Sow. non Phil.), but a little narrower, and those from 

 West Island in Torres Straits are of a peculiar short stunted 

 growth. 



3. C. paiiens, Bayle, = C. rugosum, Wood (non Lamarck), of 

 which species C. hreve, Quoy and Gaimard, appears to be a variety, 

 may be only a form of C. morus ; still there is a character about 

 the coarse ribbing and granulation and the blotchy irregularity of 

 the painting which seems to demand their separation. Besides, 

 MM. Quoy and Graimard state that the animals present certain 

 differences. 



In conclusion, I should observe that the C. tuberculatum, of Sowerby 

 (Conch. Icon. figs. 21 a, 6) is a peculiarly coloured specimen of this 

 species (C. patiens) ; also that the sheU figured as O. bornii (Thes. 

 fig. 175 ; Conch. Icon. fig. 26) is the true C. carbonarium of Philippi, 

 fig. 59 of the Conch. Icon, not representing the latter species, but 

 merely, as already stated, a form of C. morns. 



O. tuberculatum, as defined by Lamarck and Kiener, is a common 

 Eed-Sea species, which has been named 0. cceruleum by Sowerby 

 (Thes. Conch, vol. ii. p. 866, pi. 179. figs. 61, 62). 



67. CeritMum nigro-balteatum. (Plate V. fig. N.) 



SheU elongate, pyramidal, white, banded with brownish black 

 above the suture, around the middle and base of the last whorl. 

 Volutions about twelve, constricted above ^at the suture, longitudi- 

 nally strongly costate and spirally ridged and sulcated. The costse 

 are prominent, about nine in number on the upper whorls, somewhat 

 interrupted by the depression beneath the suture. The spiral ridges 

 are rather prominent upon the costse and unequal in thickness ; 

 there are about four principal ones and several smaller intervening 

 ones. On the body-whorl (in the single specimen under examina- 

 tion) the costse are rather finer and about eleven in number — ^one, a 

 little stouter than the rest on the left side, extending to the base 

 and forming a lateral varix, the others becoming obsolete a little 

 below the middle, where the whorl is somewhat angulated and con- 

 cave below the angle. The transverse principal lirae number about 

 six, of which the two lowermost are granulous, white, and situated 

 between the dark base and the zone above the middle. The lower 

 part of the whorl is finely concentrically striated and Urate. Aper- 

 ture broadly suboval, obUque. Basal canal short, obUque, sUghtly 

 recurved. ColumeUa obUquely arcuate, blackish. Labrum thickened 

 by the last costa, grooved and Urate within. Length 15 miUim., 

 diameter 6. 



Hab. Prince of Wales Channel, 5-7 fms. ... 



This species is readily recognized by the pecuUarity of its colours, 

 the depth of the subsutural depression, and the concave base of the 

 last whorl.
