6 Mauritius ; coll. G. Nevill and J. Caldwell, Esqrs. 



Very closely allied to L. ohesa, but smoother and of different 

 coloration. They may be only varietal forms ? Tiiese speci- 

 mens are most admirably and exactly represented by Pliilipiji, 

 III, PL VI, fig. 6, as L. leevis, Locality ? The L. Icevls oi 

 Reeve, I need scarcely say, is a totally different Australian form. 

 Prof. V. Martens would rather consider L. leevis, Phil., as a form 

 of L. glabrata.
