1414. STIZOSTEIUOX ('AN.Vl)KXSE (Smith). 



(Sauger ; Sand Pike.) 



Head 'Si ; depth 4* to 6; eye 5 in head. D. XI to XV-I, 17 to lit; A. II, 

 11 or 12; scales 9-100 to 125-27; pores in lateral line, 80 to 95; vertebra; 

 23 + 22; pyloric ccuca 4 to 7, unequal in length. Body elongate, more 

 terete than in Stizostcdion vitrenm, the flesh more translucent; head 

 depressed, pointed ; opercular spines variable. Olive gray, sides brassy 

 or orange, with dark mottliugs, more distinct in the young, which are 

 sharply marked ; flrst dorsal with 2 or 3 rows of round, black spots, no 

 black blotch on last spines; second dorsal with 3 irregular rows of dark 

 spots ; a large black blotch on base of pectoral ; caudal dusky and yel- 

 lowish. Northeastern North America, from Pennsylvania to Tennessee, 

 Arkansas, and the Upper Missouri, especially abundant northward; 

 a smaller fish than S. ritreum and of much less value as food. The typical 

 canadense is from the St. Lawrence region, much less widely distributed 

 than the variety (jriseum, from which it differs in having the opercles and 

 bones of the head considerably rougher, the number of the opercular 

 spines (which are merely the free ends of the striie) increased, aud the 

 head more closely aud extensively scaled.

Represented in the Great Lake region and southwestward to Kentucky

1414a. STIZOSTEDION CANADENSE GBISEUM (DeKay). 

 (Sauger; Sand Pike; Gray Pike ; Pickering.) 



This is the common Sand Pike or Sauger of the Great Lake region and 

 southwestward. It differs from the typical canadense chiefly in the 

 smoother opercles and head bones, the fewer opercular spines, and the 

 less complete scaling of the head. The two need fuller comparison and 

 may prove to be distinct species, but this is unlikely. Length 10 to 18 

 inches, {griseus, gray.)

1414b. STIZOSTEDION CANADENSE BOREIM (Girard). 



This is the form found in the Upper Missouri Basin, aud dift'ers from 

 (/nseuj/i chiefly in the more slender head, which has -i snake-like aspect. 

 {boreus, northern.)
