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

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

 mens are most admirably and exactly represented by Philippi, 

 III, PL VI, fig. 6, as L. IcBvis, Locality ? The L. loevis of 

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

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

 of L. glahrata.
