Sulcobasis T.-C., Annali del Museo Civico di Storia Naturale di 

 Geneva, xix, 1883, p. 161. 



Shell large, solid, globose-depressed or depressed ; spire convex, 

 the inner whorls (and apex when not worn) showing minute hair-scars 

 arranged in oblique series ; body-whorl more or less distinctly spirally 

 sulcate beneath. Lip well reflexed. Type C. sulcoxa Pfr., pi. 29, 

 figs. 9, 10. 



Distribution, Aru Is., New Guinea, New Ireland, Solomon la. 



Anatomy unknown. Tapparone-Canefri has given a crude figure 

 of the central and inner lateral teeth of C. beatricis, showing them 

 them to lack side cusps, as usual in the genus. Doubts have been 

 expressed as to the relationship of this group of large solid Helices 

 to Chloritts (Jahrb. D. M. G. 1892, p. 94) ; but those who see the 

 shells themselves, will agree with Tapparone-Canefri that the group 

 is simply a section of Chloritis.
