Description.— Body elongate, considerably depreseed in adults ; head quite short, the 

 mnzzle blunt, decurved, shorter than the very large eye, which is three in head ; top of 

 the head flattened, somewhat concave between the orbits ; greatest depth of the head 

 nearly three-fonrths its length ; mouth moderate, nearly horizontal, the jaws nearly 

 equal ; the maxillary extending to the eye ; lateral line nearly straight, slightly 

 decurved anteriorly ; eighteen scales before the dorsal ; coloration very pale, sometimes 

 a dusky spot at base of the caudal, especially in the young ; sides with a broad silvery 

 band ; pectorals not reaching ventrals, the latter not to vent ; caudal fin long ; head 4J ; 

 depth 4i; D. 8 ; A. 8 ; scales 5-39 4 ; teeth 1, 4-4, or 1. Length 4 to 8 inches.

 AUeghaniea. 



Diagnosis. — This handsome fish may usually be best known by the 

 small size of the head and mouth, compared with other large scaled species 

 with short intestines. 



Habits.— This fish is abundant in Lake Erie, where it reaches a con- 

 siderable size. It seldom ascends the* small streams, but is taken in 

 seines in the waters of the lake. The largest I have seen were about eight 

 inches long, and it is said to grow much larger. Dr. Kirtland also found 

 it only in the lake. 



Hudsonius fluviatilis Girard (Clupea hudsonia, Clinton) is also said to in- 

 habit Lake Erie, but I have never seen specimens from the lakes. It 

 has teeth 1, 4-4, 2, and usually a dusky caudal spot.

 ceous, a slight dusky lateral shade ; no dorsal stripe ; fins plain ; head 3$ ; depth 4; D.
