1414. STIZOSTEDION CANADENSE (Smith). 



(SAUGER ; SAND PIKE.) 



Head 3i ; depth 4| to 6 ; eye 5 in head. D. XI to XV-I, 17 to 19; A. II, 

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

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

 terete than in Stizostedlon vitreum, the flesh more translucent ; head 

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

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

 sharply marked ; first 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. vitreum and of much less value as food. The typical 

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

 than the variety griseum, 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 striae) increased, and the 

 head more closely and extensively scaled.

 Stizosledimn canadense, JORDAN & GILBERT, Synopsis, 526, 1883. 



Represented in the Great Lake region and southwestward to Kentucky 

 and Arkansas by 



1414a. STIZOSTEDION CANADENSE GRISEUM (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.)

 Lucioperca pepinus, ESTES in HALLOCK'S Sportsman's Gazetteer, 322, 1877, Lake Pepin. (Coll. 

 D. C. Estes.) 



1414b. STIZOSTEDION CANADENSE BOREUM (Girard). 



This is the form found in the Upper Missouri Basin, and differs from 

 gnseum chiefly in the more slender head, which has a snake-like aspect. 

 (boreus, northern.)
