dorsal. The pectorals are large and long, reaching to the fourth anal 

 ray. The ventrals are jugular, arising an eye-length in advance of the 

 pectorals : their plane of origin is horizontal, and they reach consider- 

 ably beyond the scaly bases of the pectorals. 



Stomach siphonal with a large csecal sack. No pyloric caeca. No 

 air-bladder. 



Colours in spirit, yellowish-brown, with thirteen incomplete and 

 indefinite darker cross-bands on body and tail : a golden-green ocellus 

 on crown of head and in the apex of each opercular flap : spinous 

 dorsal white at base, black in the upper half ; second dorsal with dusky 

 bands: caudal and pectorals dusky: anal and ventrals hyaline. Length 

 43 inches. 



Bay of Bengal, 128 fathoms. 



Family, Pediculati. 



Lophids, Art. 



2. Lophius mutilus, n. sp. 



This species is distinguished from all its fellows by the structure 

 of the second part of the spinous dorsal fin, which is rudimentaiy.

Cephalic disk enormous, its width nearly equal to its length, which 

 is not much less than half the total, including the caudal. 



The head bones are marked by spinate crests, one small and bifid 

 at the pre- orbital angle ; one large and tridentate above each orbit ; 

 one at the upper limit of the clavicle, one large and trifid at the angle 

 of the clavicle, and two on the preoperculum — besides numerous ridges 

 ending in acute points. 



The eyes are large, their major diameter being nearly one-fifth the 

 length of the head. 



The mouth-cleft involves the whole breadth of the cephalic disk. 

 Small depressible fangs of unequal size in three irregular series in the 

 mandible, in two series at the pre-maxilliary symphysis, but in a single 

 series along the greater extent of the pre-maxilla: a pair of rigid fangs 

 on each side of the vomer : an uneven row of five or six rigid fangs 

 along each palatine. Gill-cleft relatively wide : three gills. 



Head and body covered with loose glandular skin, which forms a 

 row of filaments along the edge of the cephalic disk and along the 

 sides of the tail. 



Dorsal spines in the form of plain setas, the first two of which 

 have the usual position close together on the snout, while the third, 

 which is as long as the cephalic disk and nearly twice as long as the 

 second, arises behind the orbit. The second portion of the spinous 

 dorsal is represented by two distant rudimentary rays only visible by
