CLASS PISCES. 267 



The dorsal is opposite to the anal ; the stomach, 

 resembling a fleshy tube, is continued in a straight 

 canal without duplicatures, to the commencement of 

 which are attached two coeca. In 



Fistularia (properly so called), Lacep., 



There is but a single dorsal, most of which, as well 

 as the anal, is composed of simple rays. The inter- 

 maxillaries and the lower jaw are armed with small 

 teeth. From between the two lobes of the caudal 

 proceeds a filament which is sometimes as long as 

 the body. The tube of the snout is very long and 

 depressed, the natatory bladder excessively small, and 

 the scales invisible. They are found in the seas of 

 hot climates in both hemispheres \ 

 In the 



Aulostomus 2 , Lacep. 



The dorsal is preceded by several free spines, and the 

 jaws are without teeth ; the very scaly and less slen- 

 der body is widened and compressed between the 

 dorsal and the anal, and followed by a short and very 

 small tail, terminated by a common fin. The tube of 

 the snout is shorter, thicker, and compressed ; na- 

 tatory bladder very large.
