416 On the Land Shells of Bourbon. 



40. Omphalotropis expansilaeee, Pfr. 



This is another Mauritian species, my specimens from the two 

 islands being perfectly undistinguishable after a most careful 

 examination. Rare, at a considerable elevation, crawling on the 

 ground in damp woods. 



41. Omphaloteopis picturata, H. Ad., Proc. Zool. Soc. 1869, 

 p. 305. 



Another of my new species from Mauritius, where it is extremely 

 rare. I subsequently succeeded at Bourbon, with much trouble, 

 in getting a better set of specimens, but it appears to be there 

 also exceedingly local ; it is distinguished at a glance by its more 

 attenuated and produced form, and by its last whorl being ventricose, 

 perfectly rounded at the periphery, not in the least angulated 

 or keeled. A very faint keel round the umbilicus is discernible 

 in all of my Bourbon specimens. 



I have purposely not mentioned a species described by M o r e 1 e t, 

 Ser. Conch, p. 48, as Vitrina Borbonica, I cannot help having great 

 doubts of the correctness of the recorded locality ; Deshayes does 

 not include it in his Cat. des Moll, de la Ee anion. I know of no 

 species of the genus from the Mascarene Islands.
