P.S. {June 20th, ]894). — The restriction formulated by 

 Cunningham and MacMunn as above, and confirmed by my own 

 previous experience, is controverted by a specimen obtained since 

 this paper was read. The fish is structurally normal, but exhibits 

 some pigment on the blind side of the jaws and on other parts 

 anterior to the line indicated.

 By St. George Littledale, F.R.G.S. 



[Eeceived March 28, 1894.] 



One of the objects of the journey that Mrs. Littledale and I 

 made last year across the centre of Asia \ was to obtain specimens 

 of the Wild Camel (Oamelus hactrianus). On reaching Lob-Nor in 

 May 1893 we were pleased to hear that the natives confirmed my 

 opinion that we should probably find AVild Camels on the slope 

 of the Altyn Tag ; but when I asked them in what particular 

 district these animals were likely to be found at that season of the

On the 8th day after leaving the Lob we found, on the north 

 side of the Altyn Tag, the fresh tracks of a camel. The animal 

 had come in the night or early morning within a mile of our camp, 

 but winding us it had turned and bolted away. After this we
