SUCKLEY MONOGEAPH OF THE GENUS SALMO. 149 



It has many characters in common with the >S'. fontinalis^ Mitchill, 

 or common brook and pond tront of IsTew York State. The color of the 

 slciu npon the broad anterior rays of tlie nnder fins, the red spots, 

 small scales and general style, are very similar. Bnt tlie different shape 

 of the month, the notch between the iutermaxillaries, the great size, the 

 larger number of red spots, are sufficiently diagnostic. 



The two specimens of this fine trout which we possess vary somewhat 

 in their branchiostegals and fin-rays, as follows : 



(Typical.) Br. U: P. 13: D. 13: V. 10: A. 11: C— Dr. Kennerly's 

 specimen, No. 2010. Br. 13: P. 14: D. 11: V. 10: A. 10.— One supposed 

 to be from Lieutenant Mullen, No. 2011.

PARKE'S RIVER TROUT. 



Syx. — Sahno parlri, Sucklf.y, Notices of Certaiu New Species Salmouidte, New 

 York, June 15, 1861. 

 Green speekled-haclc troid. Aitkst, of tlie Kooteuays. 



Sp. Ch. — Head contained about four and a half times in the total 

 length ; its top flat ; muzzle, pointed. Tail forked ; unsiiotted. Back 

 dark-green, spotted with spots of lighter green ; sides spotted with red. 

 Scales adherent and about the size of those of *S'. halrdii. A disposi- 

 tion toward the formation of a fleshy "tit" projecting upward at the 

 point of lower jaws, with a corresponding notch ])etween the premaxil- 

 laries. Superior maxillary reaches to a point considerably behiud the 

 eye. Branchiostegals 13-14. The anterior rays of the lower fins are 

 covered with a differently-colored skin from that of the rest of the fin, 

 as in S. fontlnalis and 8. hairdii. Two teetli on the outer extremity of the 

 vomer, behind which from one to three on the shaft. 



Diagnosis. — From ^S*. campheUi it differs in lacking the cream-colored 

 or whitish spots along the back, by its large head and turned-np knob 

 at the point of the jaw. From S. hairdii it maybe recognized by its 

 larger head, which is contained but four and a half times in the total 

 length ; that of 8. hairdii being contained five times ; also by its more 

 deeply-notched tail, and by the presence of the pale greenish spots on 

 the back.
