198 TURR1TELLA. 



T. CINGULIFERA, Sowb. PL 59, figs. 38-41. 



Slender, with about twelve whorls, contracted beneath the 

 deep suture, then rounded, with a number of thin, elevated 

 spiral strise ; whitish to yellowish brown, chestnut banded next 

 the suture, sometimes with undulating transverse chestnut lines 

 or a central chestnut band made up of two or three close parallel 

 lines on the last whorl. Length, '75 inch. 



Australia. 



The t} r pe is lighter colored than usual ; T. fragilis, Kiener 

 (fig. 39), better represents the ordinary appearance of the species, 

 whilst T< fusco-cincta Petit (fig. 40) is a variety with different 

 development of the ridging, and T. parva, Angas (fig. 41), is a 

 juvenile. 



Section HAUSTATOR, Montfort, 1810. 



T. GONIOSTOMA, Yal. PL 60, figs. 51, 52 ; PL 61, figs. 53-57. 



Whorls 18 to 20, flattened in the middle, with fine spiral striae, . 

 and sometimes a few more prominent ridges ; when the latter 

 are present they usually define the flattened area above and 

 below, with occasionally some intermediate ridges upon the 

 area, and a number of stronger ridges on the base of the body- 

 whorl; ridges sometimes irregularly nodulous; first whorls of 

 the spire unicarinate in the middle; whitish, thickly marbled, 

 speckled and irregularly strigate with chestnut or chocolate- 

 color. Length, 4-6 inches.

The synonyms include T. Broderipiana, d'Orb. (fig. 53), and 

 T. Californica, Brod. (teste d'Orb.) ; T. marmorata, Kiener (fig. 

 54); T. lentiginosa, Reeve (fig. 55) ; T. punctata, Kiener (fig. 

 56), and T. Banksii, Reeve (fig. 57), a juvenile. This list com- 

 prises shells nearly smooth, and those with strong revolving 

 ridges, also both slim and stout specimens, and shows a varia- 

 bility which, if common to other species of the genus, would 

 largely reduce their number. The specimens before me fully 

 suffice to make out the synonymy as I have given it. 



T. VARIEGATA, Linn. PL 01, fig. 58 : PL 62, figs. 63, 64. 



Whorls 15 or 16, the first few carinated in the middle, the rest 

 flattened, swollen above the suture, with four or five distant
