194 PISCES. 



In the JUGULARES, they are placed on the throat further forwards than the 

 pectorals. 



TUACHINUS, Linnceus. 



A compressed head, approximated eyes, and an oblique mouth; the first 

 dorsal very short, the second very long ; pectorals large, and a stout spine on 

 the operculum. They generally remain concealed in the sand ; wounds 

 inflicted by the spines of their first dorsal are much dreaded, but their flesh is 

 esteemed. Several species are found in the Atlantic, &c. 



Track, draco, Lin. (The Dragon-Weaver.) Grey and reddish, with 

 blackish spots ; blue streaks and yellow tints ; thirty rays to the second dorsal ; 

 flanks obliquely striated. 



One of the most remarkable genera of the Jugulares is that of 



URANOSCOPUS, Linnaeus. 



So called because the eyes are placed on the superior surface of the nearly 

 cubical head, and look upwards : the mouth is cleft vertically ; the lower part 

 of the preoperculum is crenate, and there is a stout spine to each shoulder ; 

 but six rays in the branchiae. In the mouth and before the tongue is a long 

 and narrow slip, which can be protruded at the will of the fish, and serves, it 

 is said, to attract small ones, while it remains concealed in the mud. They 

 are commonly termed Star-gazers. 



In a third division of the Percoides, the ventrals are inserted further back 

 than the pectorals: they are the ABDOMINALES. The first genus is 



POLYNEMUS, Linnesus. 



So named because several of the inferior pectoral rays are free, and form so 

 many filaments ; the ventrals are not very far back, and the pelvis is still sus- 

 pended to the bones of the shoulder. They are allied to the Percoides by the 

 teeth, either small and crowded, or bent back like those of a wool-card, which 

 arm their jaws, vomer, and palate ; but their snout is convex, and the vertical 

 fins scaly as in many of the Scienoides : the two dorsals are separated, the pre- 

 operculum is dentated, and the mouth deeply cleft : they are found in all the 

 seas of hot climates. 



Pol. paradiseus, Lin. (The Mango Fish.) So called from its fine yellow 

 colour ; has seven filaments on each side, the first of which are twice the 

 length of the body. It is the most delicious fish found in Bengal. 



In the succeeding genera the ventrals are altogether behind, and the pelvis 

 no longer adheres to the bones of the shoulder. 



The genera are Sphyraena, Paralepis, and Mullus, or the Surmullet of 

 Europe.
