OBSERVATIONS ON FISHES FROM THE CAROLINE ISLANDS. 

 BY HENRY W. FOWLER. 



Among the presentations made to the Academy of Natural 

 Sciences of Philadelphia by the late Prof. E. D. Cope was a col- 

 lection of marine Fishes, comprising forty-fiv^e specimens, from the 

 Caroline Islands. Most of these specimens are in a fair state of 

 preservation. They have been made into dry preparations or 

 skins, some of them being only one-half of the skin of the orig- 

 inal specimen, but most of them are entire, the bodies having 

 been filled out and varnished on the outside. It is unfortunate 

 that the data are very meagre, no precise localities being given. 



EXOCOETIDJE. 

 1. Cypsilurus quindecimradiatus sp. nov. Plate XVII. 



The form of the body is elongate and spindle-shaped. Head 

 flat and broad above, compressed laterally so that the lower surface 

 is rounded, 4J in the body without the caudal. Eye 3i in head 

 and about 1| in the interorbital space, which is level, the orbits 

 being placed in the upper anterior part of the head and with iheir 

 lower margins below the lower jaw. The eye is also contained 

 1^ in the space between its posterior margin and that of the 

 operculum. The length of the snout, from the tip of the upper 

 jaw, 1^ in the eye. The mouth terminal, superior, the lower jaw 

 projecting, and with the cleft inclined moderately. The posterior 

 margin of the eye is nearer the origin of the P. than the tip of the 

 upper jaw. Teeth minute. Branchial aperture large. Opercles 

 large, scaled. The greatest depth of the body, which falls consider- 

 ably short of the length of the head, is contained in the total length 

 of the body about six times. The origin of the P. is situated on a 

 level with the pupil of the eye, the radii of the fin about 14, the first 

 and second somewhat enlarged and the third and fourth the long- 

 est ; of the former, which are simple, the second is bifid for the ter- 

 minal half or more, while the rest of these rays are all branched. 

 The outstretched P. probably reached l^ackward to the eleventh
