ORTHODON, Gir. 



The species of this genus bear a general resemblance to Gila, but the 

 insertion of the fins, particularly the ventrals, is different. In dental pecu- 

 liarities, it has some affinity with Hybognatlius.

This species, called "Chub "by the Mormon settlers, is extremely 

 abundant in Utah Lake, and also in the Provo River, running into this 

 beautiful sheet of water. Spawn in May and June, and are terribly destruc- 

 tive to small fish and spawn, eating their own as well as others'. Run up 

 the stream to spawn, depositing their eggs in muddy places. Average price 

 five cents per pound. Are considered a fair table fish. Will bite any time 

 at anything, and almost anywhere in Provo River. 



NOTE. Professor Cope declines to be answerable for the locality 

 named, as he considers this fish an exclusively Pacific slope form ; we have 

 consequently marked its locality doubtful.
