418 TURCICA. 



Thalotia maculata Brazier, Proc. Linn. Soc. N. S. Wales ii, p. 

 44, 1877. 



Described and figured from specimens received from Mr. Brazier. 



T. STELLATA A. Adams. PI. 67, fig. 77. 



Shell elongated-conic, slender, strong, white, imperforate. Whorls 

 of the spire strongly, acutely carinated above each suture, and 

 bearing numerous short triangular spinous tubercles there. Above 

 this carina each whorl has 3 spirals ; the upper is low, wide, bluntly 

 tubercled, the two median are narrow equal lirse; the interstices are 

 lamellose-striate. The base has 4 coarse concentric ribs, the outer 

 one largest, interstices clathrate. Whorls 6, the last carinated at 

 periphery. Aperture rounded-rectangular, angular at the position 

 of the peripheral carina, with sulci inside corresponding with the 

 ribs of outer surface. Columella short, vertical, straight, and in the 

 young specimen before me, not dentate, but according to Adams 

 terminating in a tooth. Alt. 9, diam. 7 mill.

Turcica stellata Ad., P. Z. S. 1863, p. 508. 



I have described and figured a shell which I believe to be the 

 young of stellata. It is allied to the following species. Both may 

 be found to belong in the typical section of Turcica rather than in 

 Perrinia. 



T. CHiNENSis Sowerby, Jr. PI. 34, figs. 24, 25. 



Shell trochiform, white ; spire elevated, acute ; whorls 9, separated 

 Toy canaliculate sutures, the first 2-3 smooth, the rest coucavely 

 sloping, obscurely obliquely striate, above concavely depressed with 

 a corona of numerous plicae, beneath margined by a rounded 

 corrugated spiral carina, beneath the carina profoundly canaliculate 

 and pitted ; base convex, sculptured with 6 rather close, roughly 

 transversely plicated ribs, the interstices pitted; aperture subrotund, 

 throat pearly, lirate ; columella nearly straight, pearly, obscurely 

 unituberculate. Alt. 20, diam. 19 mill. (Sowb.) 



Hong Kong. 



Turcica eJiinensis Sowb., P. Z. S. 1888, p. 569, t. 28, f. 8, 9. 



Compared with Turcica elisce A. Ad., the body-whorl is larger in 

 proportion to the spire, the keel more prominent and the suture more 

 deeply excavated. The whorls have two rounded nodulous keels, 

 the space between which is smooth excepting for the fine oblique
