A MARINE GOLDFISH. 



Apcgon seU'icauda 



A LITTLE tro|)ical salt water fish having 

 the true goldfisli color was received at tile 

 Aquarium the last week in July, the gift 

 of Dr. A. G. Mayer, Director of the Carnegie 

 Laboratory for ^Marine Biology. 



The golden color jiales to silvery below, as it 

 does in the real goldfishes. There is a rounded 

 black S))ot on either side below the second dorsal 

 fin. as well as a saddle-sha|>ed blotch on the 

 upper part of the caudal peduncle which sug- 

 gested the specific name sellicaiida. The spe- 

 cies is a rare one and was not described until 

 1890. The specimen received at the Aquarium 

 was an unusually large one, about three inches in 

 length and was taken at the Tortugas Islands. 

 Florida. Although it had lived in confinement 

 at the Carnegie Laboratory for several weeks 

 before shipment, the transportation in a small 

 jar was evidently more than it could stand and 

 it lived only a few days 

 after reaching the Aijuar- 

 ium. 



It should he iiotiil th.-it 

 this species is iitit related to 

 the fresh water goldfislies. 

 but belong.s to tlie family of 

 cardinal fishes (Clifildilip- 

 ferulae) closely related to 

 the perch family. R. C. O.

Night Opening at the .lijiiariuiii : Begin- 

 ning witli September 22 the Aquarium has been
