NOTES ON WITH ILLUSTRATIONS OF AUSTRO- 

 MALAYAN LAND SHELLS. 



By E. R. SYKES, B.A., F.L.S. 



(Plate vi.) 



Recently (') I described a few shells from the Austro-Malayan Region; 

 illustrations of them are now given, 



Papuina wallaceaxa. — For P. aurora var. b., at p. 65, read P. 

 aurora var. ? . 



Papuina callosa. — Compare P. pseudolanceolata, Dautz., which 

 latter, if it prove to be identical, has a few days priority. 



Leptopoma lamellatum. — There appears to be a good deal of con- 

 fusion in this group. In my view it is probable that L. tissotianum, 

 Crosse, multilahre, Lamk., and scalare, Adams, are all varying forms of one 

 widely scattered species. Dr. Kobelt has in "Das Tierreich " placed 

 the Lamarckian species as a monstrosity of L. massenae, a view which, 

 taken though it has been by Pfeiifer and others, has been adversely, and 

 I think correctly, criticised by Tapparone-Canefri. 



It may be pointed out that the figures recently given in the " Con- 

 ch ylien-Cabinet," purporting to represent L. scalare, Adams, do not 

 agree with Adams' figures, and are probably taken from a Halmahera 

 species and not from the Waigiou shell.
