 Calamus macrops, Jordan &. (Jilbert, Syn. Fisli. N. A., 1883, 927 (Garden Key). 



Habitat: AVest Indies, iioith to Florida Keys. 

 Etymology: Calamus, a reed, the er|iiivaleiit of pez de lilnma. 

 This species, described in detail iu the paper of Jordan & Grilbert 

 above nieutioued, is generally conuuon about Key West and Havana, 

 reaching a length of 15 inches. It is, however, nowhere so abundant 

 as proridens or bajonado. Among the specimens iu the museum at 

 Cambridge are some of the types of Calamus orhitarius. In some of 

 these none of the canines are turned forward, and none of the speci- 

 mens collected by Dr. Jordan show this character. In others the 

 outermost of the seven or eight canines in the ujiper jaw is turned 

 directly forward, as in C. proridens. Some of these als* > show an approxi- 

 mation to the head coloration of C. proridens. The dorsal spines and 

 the depth of the preorbital show that all these belong to C. calamus. 

 Calamus megacephalus Poey is based on specimens of C. calamus^ with 

 the antrorse canines of G. proridens. The implication of a confusion 

 in Poey's description made by us (Proc. U. S. N. M. 1883, 16, 18) is 

 probably unwarranted, as his specimens at Cambridge agree with his 

 description. The direction of the teeth is less valuable as a diagnostic 

 character than our specimens led us to suppose. 



98. CALAMUS PRORIDENS. (Little-head Porgy ; Pez de Pluma.) 



Calamus megacephalus Jordan & Gilbert, Syn. Fish. N. A., 1883, 926 (Florida Keys; 



not of Swainson). 

 Calamus pennatula Jordan & Gilbert, Proc. U. S. N. M. 1884, 1.5 (Key West, Havana; 



not of Gnichenot). 

 Calamus proridens Jordan & Gilbert, Proc. U. S. N. M. 1884, 150 (Key West). 



Habitat : West Indies, north to the Florida Keys. 



Etymology: Prora, prow; dens, tooth, from the projecting canines. 



This species, the most brightly colored of the genus, is very abun- 

 dant about the Florida Keys. It is not quite so common either at Key 

 West or at Havana as Calamus bajonado, but in both places either 

 species far outnumbers all the remaining species combined.
