also from Orizaba, which are exactly similar to the typf s. 

 The number of rays in the dorsal tin is usually 12, but varies 

 from 11 to 13. Each scale on the body has a rather broad 

 blackish marginal or intramarginal crescent. 



In the following table, based only on female specim3n3, 

 are given in the first column (A) the number of dorsal rays 

 and in the others the following measurements in millimetres : — 

 (B) total length, (C) length to base of caudal, (D) length of 

 head, (E) distance from tip of snout to origin of dorsal, 

 (E) longest anal ray.

 coUected by Dr. A. C. Buller. ( 



In the typical form of P. bimaculatus the scales of the body 

 have narrow dark edges, forming a network which usually 

 fades out below. In five specimens from San Domingo de 

 Guzman, collected by Dr. A. C. Buller, the scales of the 

 middle series have very broad dark edges, giving tlie appear- 

 ance of a blackish longitudinal band from operculum to base 

 of caudal. This well-marked variety may be called Pseudo- 

 xiphopJiorus himaculatuSy var. tceniaius.

Since the publication of my report on the fishes collected by 

 Mr. R. Gordon Smith in the Inland Sea of Japan* the 

 British Museum has received a further series from him, which 

 contains examples of three species which appear to be new to 

 science. 



fifteen specimens of P. bimaculatus from the Rio Toiito,also collected by 

 Dr. Gadow, tliree have 16, seven have 15, and five have 14 dorsal rays.
