Type No. 24,343, A. N. S. P. New river, Dade collnt3^ Fla. Coll. 

 Mr. James Spear. 



One example. This species is related to Merulinus carolinus, M. 

 scituhis, M. roseus and M. alatus. It is closer to the latter in squama- 

 tion, but differs in more gill-rakers and shorter pectoral. The pre- 

 operciilar spine is also shorter. From the other species it is chiefly 

 distinguished by its bright salmon-pink anal fin. 



(Sal)no, the salmon, color, color; referring to the anal fin.) 



15. Prionotus evolans (Linnajus). 



1766. [Trigia] evolans Linnaeus, Syst. Nat., Ed. XII, p. 498; in Carolina. 



Color in alcohol dull olivaceous-dusky above, the lower surface 

 whitish. Back \Adth three dark cross-bands, and indistinct darker 

 mottlings. Head also mottled with darker, sometimes forming diffuse 

 lines. A blackish bar across the interorbital space. Dorsals and 

 caudal grayish-brown diffused with darker. Pectoral slaty-black with 

 rather large round blackish spots and the edge of the inner ray whitish. 

 Other fins white, the ventrals soiled a little on their median outer sur- 

 face. Inside of the gill-opening dull yellow, reddish on the shoulder- 

 girdle. Eye deep gray-brown. 



One example 9f inches long, from New river. 



ECHENEIDID^. 



16. Echeneis alba-cauda MitchiU. 



1817. Echeneis alba-cauda Mitchill, Amer. Month. Mag. Crit. Rev., II, 

 p. 244; in the bay of New York, June 22, 1815. 



Color in alcohol dull brown. A broad lateral l^lackish-brown band 

 running from the mouth to the base of the caudal, and bordered nar- 

 rowly below wdth dull slaty-white. Lower rays of the dorsal and anal 

 dusky-brown, and this color extending forward on these fins for the 

 same height, but becoming a little pale. The remaining outer portions 

 of the anterior rays and edges, narrowly, of the others, whitish. Caudal 

 blackish, with the upper and lower corners narrowly whitish. Yen- 

 tral and pectoral blackish, with grayish posterior margins. Iris 

 blacldsh-brown. 



Length 5f inches. 



One example taken off of a large shark, evidently Scolidon terrce- 

 novcel, judging by a photograph, captured in Carson's creek at Bis- 

 cayne Bay. It has 22 laminae in the disk, and the median caudal rays 

 project. I prefer the separation of this species from the Indian, until 

 examples are compared.
