 India; Burma; Pegu; Oeylou; Canton Eiver, China 1 I believe that 

 Mous&ou's U. evanescens is L. marginaXis, but can it be from Java*? 



^I use Lamarck's name for this species because the U. testiidinariiis and truncatus 

 were only briefly and imperfectly described, and never figured, their habitats being 

 given as Greenland. Lamarck refers to the figures in Enc. Meth., pi. 247, figs. 1, 

 la, lb, Ic, which very accurately represent the shell we know as Unio marginaUs. 



■^Not Lea's corrianus at all, but very ditferent. I change the name to hanleyi.
