Jordan and Evcrmann. — Fishes of North America. 1961 



Pectoral barelj' reaching front of anal ; spinous dorsal very low, from \ to 

 \ as high as soft dorsal, its base from its first spine to first ray of soft 

 dorsal 1^ in head; dorsals barely meeting, not at all connected. Color 

 light gray, somewhat mottled; veutrals and anal colorless, other fins 

 crossed with wavy lines ; a soft spot on each end of spinous dorsal. Eagle 

 River, a tributary of Grand River, Colorado, Colorado River Basin. Here 

 described from 4 siiecimens from 21 to 31 inches in length, collected at 

 Gypsum, Colorado, from the Eagle River. It has hitherto been confounded 

 with Coitus semiscaber, which was taken in abundance at the same place 

 and recorded as " Coitus Ixiirdii punctutatus." We have compared this sjie- 

 cies with specimens of Coitus heldiiujii from Birch Creek, Idaho, and with 

 a cotype of Coitus philonips from Field, British Columbia. It differs from 

 both of these in having the mouth and eyes smaller, and from the Field 

 specimen in having a deeper body. (Name for Miss Anna Louise Brown, 

 artist of the Hopkins Seaside Laboratory.)

2333. COTTCS SPILOTUS (Cope).* 



This species is thus described : "D. VIII, 17 ; A. 13 ; V. 1, 4 ; P. 15 ; bran- 

 chiostegals 6. Entering the section with 5 A'entral rays, and with an 

 elongate body, resembling apparently the hairdii, except in its short and 

 anteriorly situated ventral fins. In wilsonii the eye is smaller, and frontal 

 width greater; the pectoral rays are branched, in the present species sim- 

 ple. In richardsonii the vent is said to be the median point of distance 

 from the muzzle to the caudal fin; here it is much nearer the muzzle. In 

 coi/natus we are informed that the anal tin has a more posterior position. 

 The length of the head is contained 3 times plus 1 orbital diameter from 

 end of muzzle to base of caudal fin ; said diameter enters 41 times length 

 of head, and is | greater than interorbital width. The head is slightly 

 contracted laterally, and not so depressed as in C. alvordii, giving the 

 orbits less vertical range. One preopercular spine. Insertion of pectorals 

 oblique, rays undivided, reaching anus and anterior rays of second dorsal; 

 ventrals below middle of pectoral, insertion in advance of dorsal, extend- 

 ing halfway to vent. Width of isthmus equal fr'om border of (closed) pre- 

 maxillary to opposite hinder margin of pupil. Dorsal outline low, 

 regularly descending to near end of second dorsal. Greatest depth enters 

 5 times from end of muzzle to base of caudal. Lateral line disappears 

 between middle and end of caudal. First dorsal low, first ray f of second, 

 third, and fourth ; anal begins opposite fourth ray of second dorsal. Caudal 

 fin rather small, rays once divided. No trace of palatine teeth. Above 

 brown, below yellowish, everywhere densely j)unctulated with darker, 

 except between the vent and anterior to ventral fins ; dorsal, caudal, and 

 pectoral fins barred; anal yellowish; base of caudal and dorsal spots 



*Dr. Bean records a fisli from York Factory, Hudson B.-iy, under the name Uranidea 

 ipilota. Cope, " D. IX, 18; A. 12; V. I, 4. One specimen nieasiiring 4 inches without tail, 

 which is wanting. Vomerine teeth onlj'." (Bean, Proc. U. S. Nat. Mus. 1881, 127.)
