a third (31-100) of the head's length. The head itself is not so large, form 

 ing only a seventh of the total length. Finally, the first dorsal spine is repre- 

 sented as heing nearly over the axilla of the pectoral fin. M. Poey distin- 

 guishes it further from his A. altivelis in his correspondence as follows :

In honor of the gentleman who has thus distinguished the species, it may

On a new Species of PRIACANTHUS discovered in Narragansett Bay, R I. 



BY THEuDOkE GILL. 



During a recent visit to Philadelphia, I discovered in the Museum of the 

 Academy of Natural Sciences, a species of Priacanthus, which was at once 

 discovered to he most nearly allied to a species of Japan. In the same bottle 

 was a note confirming the label and giving the following information : " From 

 Mr. Philip Caswell; taken at Cananicut Ferry, Narragansett Bay, Sept., 1860. 

 Color like Gold Fish." I am assured by Dr. Bridges, one of the principal 

 ichthyologists of Philadelphia, that he is himself conversant with the circum- 

 .stames of its discovery, and that there can be no doubt of the fact of its 

 having been found in Rhode Island as well as Sarothrodus maculo ductus 

 and Hyporthodus Jiavicauda, described in a previous number of these Pro- 

 ceedings, from the same State. 



The species may be named 



Pkiacanthus altus Gill. 



The height of the body equals about a half of the total length, inclusive of 

 the caudal fin. The head forms more than a third of the same. The diameter 

 of the eye in the young specimens is contained 1\ times in the head's length. 

 The posterior nasal aperture is a long curved slit. The angle of the preoper- 

 culum is armed with a strong spine passing beyond the branchial aper- 

 ture. The caudal fin truncated ; the spines of the dorsal and anal fins longi- 

 tudinally striated. The scales are proportionally large. The whole body is 

 rough.

The body appears to have been reddish or rose colored ; behind and at the 

 pectoral region, the color is plumbeous, but perhaps accidentally so. The 

 dorsal fin has its spinous portion punctulated with very numerous blackish 

 dots, and with two rows of large roundish clear spots, besides a row of smaller 

 basal ones and one of similar small spots near the margin ; the diameter of 

 the large spots nearly equals the space between adjoining spines. The soft 

 portion of the dorsal, as well as the anal and caudal fins, are more or les? 

 dotted with blackish ; the spinous portion of the anal also so thickly covered 

 as to be blackish. The pectoral fins are entirely blackish, the dots being 

 densely crowded. 



The specimen is little more than an inch (1 1-5) in length.
