FAMILY FISTOLARIDiE — FISTULARIA. 233 



ranee at the chin. Both jaws armed with numerous small acute and recurved teeth. Gill- 

 covers radiated, with a flat trifid spinous elevation on the upper and anterior part of their sur- 

 face. Over the opercle, a strong bony serrated or rather spinous ridge, 0"7 in extent. Orbits 

 elliptical, • 5 long, and • 35 apart. There are prominent angular serrated processes on the 

 anterior and posterior portions of the upper margin of the orbits. Head above with longitu- 

 dinal furrows on its surface. 



The dorsal fin small, pointed, triangular, and placed on the posterior third of the body. 

 Pectorals broad, subtruncate, and placed • 25 posterior to the opercle ; their length to their 

 width as one to three. Venirals 2' 5 behind the pectorals ; very small, distant, and 0'4 long. 

 Anal similar in shape and size to the dorsal, against which it is placed. Caudal deeply forked 

 from between its lobes arises, as if a continuation of the lateral line, a strong filament, elastic 

 as baleen. This filament is nine inches long, jointed at the base, and delicate towards the tip ; 

 at its base arises a short filament, and at the distance of 6'0 from the base, another very short 

 bifid filament. 



Color. Upper part of the body reddish brown. A narrow bluish longitudinal band along 

 the sides, through the centre of which passes the lateral line. Abdomen light-colored. Dor- 

 sal and ventrals white. 



Length, 19" 0; of the caudal filament, 9*0. 

 Fin rays, D. 14 ; P. 16 ; V. 6 ; A. 14 ; C. 16 



The species of this genus are still involved in great obscurity. Cuvier, in his Regne Animal, 

 cites three species. Cloquet, in the Dictionnaire des Sciences Naturelle&, asserts that only 

 one is known. We are to await the publication of the work of Cuvier and Valenciennes 

 before this point will be definitively settled. There certainly appears to be two species on 

 our coast ; the one just described, and another very briefly indicated by Dr. Mitchill. I have 

 to return my thanks to Dr. Storer, for his kindness in favoring me with an opportunity of 

 examining and figuring the specimen which furnished him with his description.

Till New-Yort Tnanptt-JUh, F. neo-tboraceruu. Mitchell, Lit. and Phil. Soc. Vol. 1, p. 437, pi. 3, fig. 8. 



Characteristics. A row of pale spots on the sides. Orbits of the eyes with angular processes 

 or spines. 



Description. Body rounded, slender; its depth less than its thickness. Tube 2-5 long 

 grooved or fluted on the sides. The lower jaw projecting beyond the upper. Gill-opening 

 ample ; opercle radiated. Orbits large, contiguous, and beset with angular processes (in the 

 figure representing spines). Lateral line as in the preceding. Surface smooth and scaleless. 

 Ventrals small, and far apart. Dorsal and anal opposite. Caudal filament 4-0 long.
