A single distinct spine on the preorbital : three teeth on the sharp over- 

 hanging upper border of the orbit. Humeral spine trifid. 



Byes large, their diameter being a fifth the length of the disk and equal to 

 the width of the interorbital space. 



Hyoid and neighbouring parts of branchial arches dusky, but not distinctly 

 pigmented. 



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

 mandible, in two series near the symphysis of the upper jaw, but in a single 

 series along the greater part of the upper jaw. A pair of rigid fangs on each 

 side of the vomer, and five or six along each palatine. 



The third dorsal spine is much the longest, being as long as the cephalic 

 disk : all three are plain bristles. The second portion of the spinous dorsal 

 consists of two small spines only visible after dissection. Caudal about a fourth 

 the total length (itself included). Pectorals narrow. 



Colours in spirit, mottled brown. 



A single specimen, 5; inches long, from the Bay of Bengal, off the Madras 

 coast, 128 fathoms. 



Regd. No. 13438. 



This species is at once distinguished by the rudimentary second part of the 

 spinous dorsal. 



34. Lophius lagubris, Alcock.

B. 6. D. I. I. I. I. 7-8. A. 5-6. P. arc. 13. V. 1.5. 



Cephalic disk subcircular, about half the total length, caudal included, 

 scantily fringed with slender tassels as in Lophius mutilus. 



A single distinct spine on the preorbital ; 3 teeth on the sharp overhanging 

 upper border of the orbit. Humeral spine trifid. 



Byes moderate, their diameter about a seventh the length of the disk, and 

 rather less than the width of the interorbital space except at its fore end. 



Hyoid and neighbouring parts of mouth slightly dusky, not distinctly 

 pigmented. 



Teeth as in Lophius mutilus. 



All the dorsal spines are simple filaments : the third is much the longest, 

 being as long as or even longer than the cephalic disk. The second part of the 

 dorsal fin consists of a single short slender filament, about twice as long as the 

 eye. Caudal rather more than a fourth the length of the total (itself included). 

 Pectorals narrow.
