FISHES OF NEW YORK 361 



the number of the dorsal spines, which is generally four in 

 1 a c i n i a t a , but sometimes five, as observed in examples 

 from Great Egg Harbor bay, N. J., no. 45158 U. S. National 

 Museum. 



The rough silversides grows to the length of 4 inches; it is 

 not important for food, but serves as food for the larger fishes. 

 It was found abundant at Somers Point N. J. in August 1887, 

 where it had previously been unknown. The largest individual 

 taken in Great Egg Harbor bay, 4 inches long, was secured at 

 Longport N. J. 



The only example so far known in New York waters was 

 caught in Mecox bay, L. I. Aug. 1, 1898. Though the bay was 

 seined repeatedly afterward in search of the fish, no other speci- 

 mens were seen. The following notes were obtained: D. V, I, 7; 

 A. I, 20; P. 14; V. I, 5. Scales 7-47. 



Genus LABIDESTHES Cope 



This genus differs from Menidia chiefly in the prolongation 

 of the jaws, both of which are produced into a short depressed 

 beak. The scales are small as in Leuresthes and Basil- 

 i c h t h y s , their edges entire.
