GENUS VI. SACCOPHARYNX, Mitchill. 



The trunk, susceptible of being inflated like a thick tube, is terminated by a 

 very slender and very long tail, along which proceed a very low dorsal and 

 anal, and unite at its point. The mouth, armed with sharp teeth, opens far 

 behind the eyes, which are quite near the very sharp point of the muzzle. Its 

 gills open by a hole below the pectorals, which are very small. 



1. Saccopharynx chordatus, Mitchill. 



Skin smooth and scaleless. Of a dusky brown color ; a whitish line on each side of the 

 back; interior of mouth black. Lower jaw without teeth ; upper jaw, for about an inch and 

 a half, furnished with a row of bony, hooked teeth. Head small ; eyes small. Dorsal fin 

 appearing like a narrow riband, and reaching to the tail; dorsal, caudal, and anal united. 

 Filiform excrescences on each side of the whitish stripe all the way from the head down the 

 back to the tail. Tail flexible enough to be tied into knots.

GENUS VII. AMMODYTES, Lin. 

 Head and body elongated ; gill-openings large ; dorsal fin extending nearly 

 the whole length of the back ; anal fin of considerable length ; dorsal and anal 

 fins separated from the caudal fin. Lower jaw longest. Their stomach is 

 pointed and fleshy ; they have neither cceca nor natatory bladder. 



]. Ammodytes Americanus, Dekav. 



Body elongated, slightly compressed. Back of a dirty yellowish-brown color. Top of 

 the head, and upper part of the opercula, slate-colored ; this slate or silvery-blue color passes 

 down over the opercula in a broad band to the tail, giving the fish a beautifully brilliant ap- 

 pearance ; beneath this, the sides and abdomen are silvery. The dorsal fin commences over 

 the extremities of the pectorals. The anal fin is just one third the entire length of the fish. 

 Without the strong forked teeth on the vomer, which exist in the Tobianus.
