(June 20th, 1894).-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. 3. Field-Notes on the Wild Camel of Lob-Nor. By ST.
