462 TELEOSTEI 



1. With a very wide head and large mouth, terminal, or directed 

 upwards ; and the gill-opening below or behind the base of the pectoral. 



Family LOPHIIDAE. In these Fishing-Frogs, or Anglers, the pectoral 

 fin is scarcely geniculated, and has two radials. The pelvic has one 

 spine and five jointed rays, and is not much modified. 



Lophitis, Art., ' Angler ' ; tropical and temperate seas ; Eocene, Italy. 

 Ghirolophis, Sw. ; Lophiomus, Gill. 



Family CERATIIDAE. The scarcely geniculated pectoral has three 

 radials. The pelvics have disappeared, also the scales. They inhabit 

 the deep seas, and the skeleton is imperfectly ossified.

Family ANTENNARIIDAE. The lobe of the pectoral forms a distinct 

 angle or geniculation, and has three radials. The pelvics have four or five 

 rays, and project outwards. As a rule, two large fleshy processes project 



above the head. Chaunax 

 lives in the deep sea and 

 can innate its abdomen 

 like a Gymnodont.

 PIG. 489. 2. The gill - pore is 



Onirodes glomerosns, deep-sea Angler from the Indian below and behind the base 

 Ocean with rudimentary subcutaneous eyes. (After Alcock, n p ii, p npP t rir n'| . fhp mmifh

of moderate size becomes 



inferior, while the snout is produced into a long tentacle provided with a 

 phosphorescent organ at its tip. 



Family GIGANTACTINIDAE. A deep-sea fish resembling the Ceratiidae 

 in structure, but covered with small spines. The pelvics are absent. 



Gigantactis, Brauer ; Indian Ocean. 



3. A rather small and more or less inferior mouth. The gill-opening 

 is above the base of the pectoral, which is strongly geniculated. The 

 pelvic fins, with five derrnotrichs, project strongly outwards, and like the 

 pectorals are adapted for walking (Figs. 487-8). Usually there is a long 

 snout, below which may be lodged the lure, the only remains of the 

 spinous dorsal. The body in the pectoral region becomes greatly 

 expanded, and is covered with tubercles or spines. 



Family MALTHIDAE. There are three pectoral radials ; the teeth may 

 be villiform. The gills may be reduced to two.

TRIBE 6. SCOMBRIFORMES. 



Although difficult to distinguish by definition from the closely allied 

 Perciformes, this appears to be a natural assemblage of related families.
