BARBUS BOCAGEI. 



middle of the body, and is higher than long, though the height is very 

 variable; the length of its base is about one-half of the length of the head. 

 The last or fourth unjointed bony ray is more or less deeply toothed in 

 the middle third of its length ; but in old examples the serrations vanish, or 

 are represented by slight irregularities. The superior hinder outline of the 

 dorsal fin is slightly concave. The broad anal fin is placed far back, so that 

 its rays sometimes reach to the base of the caudal fin, or it is sometimes much 

 shorter. The short ventral fin is under the middle of the dorsal ; it is 

 always shorter than the anal fin. The pectoral fin may be five-sevenths of 

 the length of the head, and is always longer than the dorsal fin. The caudal 

 fin is deeply notched, with pointed lobes, of which the lower may be slightly 

 the longer. This fin is seldom as long as the head. 



The scales are longer than high, and have a fan-like ornament. The larger 

 scales are above the pectoral fin, the smallest are on the neck and on the 

 throat. The lateral line runs along the middle of the side, and cephalic 

 canals extend from the inferior border of the orbit. The number of perforated 

 scales in the lateral line varies from forty-six to fifty-one ; the last three lie 

 on the base of the caudal fin. There are eight or nine rows of scales between 

 the lateral line and the dorsal fin, and five rows between the lateral line 

 and the ventral fin. 



The lowest and fifth pharyugeal tooth is a mere needle-point ; but the 

 two succeeding teeth are remarkably large. 



The colour varies with the locality. In cold clear water the back is dark 

 green or deep golden brown, with greenish spots ; the sides are lighter, and 

 the belly whitish. In muddy lakes and rivers, with warmer water, the back 

 is dirty brown, and the belly yellow. The young fishes are sometimes 

 spotted with brown. 



This species is found in the ponds, rivers, and lakes of the interior of 

 Spain, and reaches a length of one and a half to two feet. It is not met 

 with in the east of Spain, but is common in the Tagus, Douro, Minho, and 

 Xucar.

This Barbel reaches a length of seven to twelve inches, and at present is 

 known only from the Guadalquivir, in Spain. It has the bony ray of the 

 dorsal fin very strong and sharply serrated. The body is somewhat com- 

 pressed, nearly as high as the head is long, and the height is about one-fourth
