KOLLtrSOA. 05 



Coppinger at Port Jackson are like fig. 59 in tlio 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. 



'-'>. G. paiiens, Bayle, = G. rugosum, Wood (non Lamarck), of 

 whirl: species G. breve, Quoy and Gfaimard, appears to he a variety, 

 may he only a form of G. morus; still there is a character about 

 the coarse ribbing and granulation and i he 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 G. tuberculatum of Sowerhy 

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

 species (G.patiens); also (hat the shell figured as G. bornii (Thes. 

 fig. 1 75 ; Conch. Icon. fig. 26) is the true G. carbonarium of Philippi, 

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

 merely, as already staled, a form of G. morus. 



G. tuberculatum, as defined by Lamarck and Iviener, is a common 

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

 (Thes. Conch, vol. ii. p. 860, pi. 179. figs. 61, 02). 



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



Shell elongate, pyramidal, while, 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 costae 

 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 costae 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 costae 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 lira? 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 lirate. Aper- 

 ture broadly suboval, oblique. Basal canal short, oblique, slightly 

 recurved. Columella obliquely arcuate, blackish. Labrum thickened 

 by the last costa, grooved and lirate within. Length 15 millim., 

 diameter 0. 



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



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

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

 last whorl.
