234 REPORT OF THE COMMISSIONERS OF 



69. Aphredoderus sayanus {Gil/iams). Pirate Perch. — Common in a lake 

 at Patchogue, Long Island, where it has sometimes been mistaken for young carp. 

 The individuals in the Aquarium were sent by Professor Ulric Dahlgren from 

 Princeton, N. J., in October, 1897. They have never been observed to feed, and do 

 not look well. 



70. Menidia beryllina (Cope). Fkesh-water Silverside. — This small 

 silverside, heretofore found only in the Potomac River, is abundant in a little mill 

 stream at Water Mill, Long Island, where the writer seined it, September 14, 1S97, in 

 company with Fuudiilus diapliaiius, Liicania parva, Eupoiiiotis gibbosus, and Lucius 

 rcticulatus. The largest of the individuals are two and three-eighth inches long. 

 Owing to high temperature the shipment to New York was unsuccessful, none of the 

 fish having lived in the Aquarium longer than a few days. Following are some of 

 the characters : 



D. V. I, 10; A. I, 16-17 ; scales, 8-40. 



71. Menidia notata {JMitchill). Silverside ; Spearing. — This species is found 

 in Gravesend Bay almost all the year, inhabiting spring holes in winter. Individuals 

 brought into the Aquarium in the winter of 1895 ^""e still living (November 28, 1897). 

 They endure the summer temperature, which has sometimes reached 71^ degrees 

 Fahrenheit in the salt-water tanks. They feed here upon hard clams and shrimp. 



72. Labidesthes sicculus (rc/c). Brook Silverside ; Skipjack; Glass-fish. 

 — The name glass-fish is used for the species on Chautauqua Lake. Mr. Annin sent 

 some living examples April 22, 1897, but they were in a very weak condition after 

 the twelve hours' journey by rail, and soon died. 



73. Mugil cephalus {Limucus). Striped Mullet. — The young mullet are 

 abundant in Gravesend Bay in midsummer ; larger ones appear in September and 

 October. One winter, some years ago, they hibernated in the mud in Sheepshead Bay 

 and were taken with eel-spears. It feeds and thrives most of the year, but cannot 

 survive the heat of summer. Food in the Aquarium consists of hard clams and 

 shrimp. 



74. Mugil curema [Cuv. & Wt/.). White Mullet. — This appears with the 

 foregoing, but is less abundant in Gravesend Bay. 



75. Sphyraena borealis {Df Kay)- Barracuda. — Several young individuals 

 were captured in Gravesend Bay in September, 1896. The species is not common in 

 that locality. An individual five and one-half inches long was seined at Sandy Hook, 

 October 8, 1897; it lived only until October 31, and was never observed to take 

 food. The species never has been successfully reared in the Aquarium.
