 rals are more, the ventrals less than half as long as the head. 

 Ventrals inserted midway between the anal and the head.

Salmo macrostoma. 

 B. 12. D. 13. A. 14. L. lat. ca. 130.

 mouth. The narrow and slightly curved maxillary extenduig 

 considerably behind the hind margin of the orbit. The head 

 is small, only one fourth of the total length without caudal. 

 Eye small, nearly one seventh of the length of the head. 

 Teeth rather small ; one pair on the head of the vomer is 

 followed by three or four other small teeth, arranged in a 

 series. Prasoperculum crescent-shaped, without lower limb. 

 Body rather deep ; its depth being equal to the length of the 

 head. There are sixteen or seventeen scales in a series ob-
