NOTE ON Calamus proridens, A NEW SPECIES OP CALAMUS. 

 By DATID S. JORDAIV and CHARI^E.*^ H. OIL.BEBT. 



In our recent i:)aper on the genus Calamus (Proc. TJ. S. Nat. Mus., 

 1884, 14-24), we have adopted the name Galaynus pennatula Guichenot, for 

 the "Little Head Porgy" of the Key West fishermen, supposing that 

 the following clause in Guichenot's description (Eevision des Pagels, 

 p. 116) was a slip of the pen or some similar error: "II ale corps 

 moins haut (than in 0. penna), plus allonge ; sa plus grande hauteur 

 (aux pectorales) nayant pas le tiers de la longueur totale du poisson." 



Dr. H. E. Sauvage, of the museum at Paris, informs us that Guiche- 

 not's type, taken by Plee at Martinique has a total length of m.0.260 ; 

 depth, m. .075 ; length of head, «?. .067. Its height is contained there- 

 fore nearly 3^ times in the total length and 2f times in the length to the 

 base of the caudal. 



The Calamus pennatula is therefore an elongate fish, while the species 

 described by us is an especially short and deep one. We would there- 

 fore propose for the species represented by our specimens from Key 

 West and Havana the name Calamus proridens Jor. & Gilb. The specific 

 name is intended to refer to the peculiar forward-directed canines of 

 the upper jaw.
