1898,] OK FISHES OF THE PAMILT MORMTRIDJE. 775 



Chinese Customs, to whose kindness he has been indebted for 

 many facilities in carrying on his scientific work. 



23. Mus PYGM^us M.-Edw. 



Three skins and five specimens in spirit. 



This is the Eastern representative of the European Harvest- 

 mouse. Mr. La Touche's specimens, as also an example from 

 Shanghai sent home by Consul Swinhoe, have tails somewhat 

 longer than Prof. Milne-Edwards gives in his description of Mus 

 jpyc/mcmis. The same author gives the hind feet as 18 mm. in 

 length. In my notes on the type specimen in the Paris Museum, 

 however, I find that the tail is said to be " doubtfidly perfect," 

 and the hind feet are recorded as 13"9 mm., so no doubt 18 is a 

 misprint for 1 4, a length which quite agrees with \\hat is found in 

 the Kuatun specimens. 



24. MiCEOTUS MELAIfOGASTER M.-Edw. 



Ten specimens. 



" This appears to be common enough, though I saw only one 

 live specimen, which my little dog routed out of its run in the 

 brushwood near the path leading up to the village." 



25. Ehizomts sinensis G-ray. 



This fine Bamboo-rat seems to be common, as a good number 

 of specimens have been sent home at various times by Messrs. 

 La Touche & Kickett. 



" Found in the bamboo plantations, about 3000 feet. Toung ones 

 were brought to us in April, and we bought three very young 

 ones alive, but they died after a few days' captivity." 



26. Lepus sinensis Gray. 



Two specimens, presented in 1896. 



4. A Revision of the Genera and Species of Fishes of the 

 Family Mormyrida:. By G. A. Boulenger, F.R.S. 



[Eeceived November 3, 1898.] 

 (Plate LI.) 



The numerous additions to the freshwater Fish-Fauna of Africa, 

 which it has lately been my good fortune to describe, have 

 necessitated much revision of the work of my predecessors in this 

 department. With no group was this more necessary than with 

 the Mot^iyridce. 



Although a considerable number of genera have been proposed 

 and defined in more or less satisfactory manner by Johannes 

 Mijller, Marcusen, Gill, and Bleeker, the tendency has of late been 

 to revert to the view of Valenciennes and to unite all the species 

 under the head Mormyrus, with the exception of GymnarcJivs,
