Note sur le genre Monocondylcea de d^Orhigny, et description 

 d^une esplce nouvelle: RY S. PETIT DE LA SAUSSAYE. 



Mbnocondyloea Camhodjensis. Cambodia. 



This species appears to resemble very closely M. crehristri- 

 ata, Anth., herein described, but M. Petit does not mention the 

 numerous small plicoe which are so very characteristic of Mr. 

 Anthony's species. 



Rectifications et additions d lefaune Malacologique de VIndo- 

 Chine: BY A. MORELET. 



The author, premising that he agrees entirely with Eoss- 

 massler, that the rectification of a bad description is more 

 useful to science than the description of a new species, pro- 

 ceeds to state that Unio ahnormis, Morlt., Rev. Zool., 1862, is 

 the same as U. gravidus, Lea, 1856; U. imperialism Morlt., 1. 

 c, is a synonym of U. Hainesianus, Lea; and that U. nianda- 

 rinus, Morlt,, Jour. Conch. 1864, is a synonym of U. scobinatus, 

 Lea. 



M, Morelet, with the greatest candor, acknowledges that the 

 publication of Mr. Lea's papers in the "Proceedings of the 

 Academy of Natural Sciences of Philadelphia," also after- 

 wards in the "Journal" of that Society, and in his "Observa- 

 tions on the Genus Unio," besides the numerous extracts and 

 notices of the paper in the various periodicals, leaves him no 

 excuse for his ignorance of these species. 



The following new species are described: — 



U. misellus, Siam. U. pellis-lacerti^ Siam. 



The author mentions that the same locality has afforded to 

 him a number of other species, apparently new ; but he hesitates 

 to describe them for the present. The two above described 

 are believed to be very distinct from any others.
