Phil. [not of Reeve], P. Zool. 8. 1845, Hab.? ; fide v. Martens, from 
Hongkong and Pt. Jackson ; sect. Melaraphe. 
6 Mauritius; coll. G. Nevill and J. Caldwell, Esqrs. 
Very closely allied to L. obesa, but smoother and of different 
coloration. They may be only varietal forms? These speci-

III, Pl. VI, fig. 6, as DL. levis, Locality? The L. levis of 
Reeve, I need scarcely say, is a totally different Australian form, 
Prof. v. Martens would rather consider ZL. levis, Phil., as a form 
of L. glabrata.

Scarcely specifically separable from L. mauritiana, as already 
pointed out by Philippi [under L. levis]. Krauss records it
