In the female above mentioned, the maxilla reaches to the front of pupil; the lower jaw 

 projects a little ; the dorsal and anal each have ten divided rays; the dorsal has a black tip ; 



the pectoral is dusky above ; the ventral and anal are pale ; the caudal is dusky towards the

40. Argyrosomus hoyi {GUI). Lake Shiner; Moon-eve Cisco. — This species 

 is recorded with certainty from Lake Michigan only. It is taken in gill-nets in deep 

 water, and, notwithstanding its small size, has become commercially important. It is 

 here for the first time announced as a member of the New York fauna, and the descrip- 

 tion following below leaves no doubt of the correctness of the identification. The fish 

 exainined, a female with ripe eggs, was taken in Canandaigua Lake, December 19, 

 1896, by Mr. Annin"s men. It was the only one caught, and was captured by becom- 

 ing gilled in the funnel of the net. Mr. Annin is satisfied that this is the lake shiner 

 of tlie fishermen, which they sometimes see in immense schools at the surtace, and kill 

 for trolling bait by shooting them.
