430 Dr. A. Glinther on the 



him to procure a specimen. This porpoise is not what, from 

 the great distance from the sea, I expected it to be, but proves 

 to be identical with, or closely allied to, DelpMnus (Neomeris) 

 meJas of Schlegel. I still consider it probable that a species 

 of PJatanista may yet be found to inhabit the Yangtsze-Kiang, 

 a river which would seem to be well adapted for the existence 

 of this type of freshwater Cetacean. 



The fishes sent by Mr. Pratt in the same consignment 

 belong to the following species : — 



Chondrostei : Acij^enser^ sp, (two very young examples 

 differing from the species hitherto known) ; Psej)hurus gla- 

 di'us, Martens (young). 



AcANTHOPTERYGii : Eleotris xantM, sp. n. ; OpMocephalus 

 argus^ Cant. ; Poly acanthus opercularis, L. 



SlLURlD^ : Silurus asotus, L. ; Macrones longirostris ■'^j 

 Gthr. ; Macrones crassilahris, Gthr. ; Macrones tcEuiatus, 

 Gthr. ; Macrones Vachellu, Eich. (A. 27) ; Macrones macro- 

 2)terusj Blkr. 



Cypeinid^: Carassnis aiiratiis, L. ] {Crossochilus monti- 

 cola, sp. n.) ; Pseuclogohio sinensis, Kner ; Pseudoqohio 2yro- 

 ductus, Ptrs. ; Pseudogohio macidatus, sp. n. ; Bhinogohio 

 cylindricus, sp. n. ; Pseiidorashora imrva, Schleg. ; Xeno- 

 cypris argentea, Gthr. ; Ctenopharyngodon idellus, C. V. 

 (specimens 2 feet long) ; Bhodeus sinensis, Gthr. ; Ochetohius 

 eJongatus, Kner ; Squalioharhus curriculus, Rich. ; Hypoph- 

 thahnichthys moUtrix, C. V. ; Chanodichthys i^ekinensis, 

 Basil. ; Culter ilishcvformis, Blkr. ', Hemiculter leuciscidus, 

 Kner ; Luciohrama typus, Blkr. ; Homaloptera Jimbriata^ 

 sp. n. 



COBITIDINA: Misgurnus anguillicaudatus, Cant; Misgurnus 

 mizolepisj sp. n, ; NemachiJus xanthi, sp. n. 



I subjoin some notes, chiefly descriptive of the new species. 



Eleotris xanthi. 



D. 6/|. A. 1/7. L. lat. 33. 



Prteoperculum without spine. Twelve series of scales 

 between the origin of the second dorsal fin and the anal. 

 The scales on the neck, cheek, and opercles are small and 

 do not extend on to the interorbital space. Scales finely 

 ciliated. The height of the body is one fourth of the total 

 length (without caudal), the length of the head two sevenths. 



* This is not a Japanese species, as I was inconectly informed when I 

 descriLed it.
