m e d i o c r i s and m a 1 1 o w a c a of the same author. Its 

 relation to in a 1 1 o w a c a was long since pointed out by Dr 

 (xill. The description! herewith appended appears to make this 

 conclusion inevitable. 



Summer herring of New York (C 1 u p e a aestivalis'). Has 

 a row of spots to the number of seven or eight, extending in 

 the direction of the lateral line. Tail forked. Belly serrate; 

 and, in most respects, resembling the C. h a 1 e c , herein already 

 described. Rays: Br. 6; P. 15; V. 9; D. 16; A. 19; C. 19. 



The figure shows a row of eight dark spots on the side extend- 

 ing as far back as the end of the dorsal fin on the level of the 

 eye. This resembles the hickory shad, Pomolobus medio- 

 c r 1 s , more than anything else, and it probably was that 

 species. 



The glut herring arrives later than the branch herring and 

 does not ascend streams far above salt water. It appears to 

 spawn only in the larger streams or their tidal tributaries and 

 at a temperature of 70° to 75°; while the branch herring spawns 

 in water as low as 55° to 60° and ascends far up the streams 

 and their small fresh-water branches. 



In Gravesend bay the glut herring is called shad herring. 

 Nov. 30, 1897, two young fish of the year, measuring about 7 

 inches in length, were obtained from that bay. In Great South 

 bay the species is called herring. A single example was secured 

 there on Sep. 29, 1890. In 1898 it was not collected either in 

 Great South bay or Mecox, in both of which the branch herring 

 was abundant. 



At Provincetown the species is known as the blueback and 

 kiouk. According to Storer, it appears there in small numbers 

 in May, but is not abundant before June 10, and it remains on 

 the coast for a short time only. The alewife, or branch herring, 

 arrives on the coast of Massachusetts about the end of March, 

 and is taken till the middle or last of May.
