 backwards, and, approaching each other, they unite at the dis- 

 tance of rather more than a quarter of an inch back of their 

 origin, forming a dorsal line, which, continued the whole 

 length of the body, is lost upon the tail ; on each side, of this 

 dorsal line, runs another, which arises at the superior anterior 

 angle of the eye, and terminates like the preceding ; beneath 

 this, is still another, commencing at the snout, and interrupted 

 cnly by the meatus of the ear, is continued like the others upon 

 the tail. These yellow lines give the beick the appearance
