This species is very closely related to, and may possibly be only a dwarf 

 variety of, Lophius setigerus Wahl, the common Fishing-frog of Japan.

Disk elliptical, nearly half the total length, caudal included, fringed as in 

 the preceding species, but more scantily. 



Two spines on the preorbital, supra-orbital margin elevated and dentated. 

 Humeral spine truncated and bifid at tip. 



Eyes of moderate size, their major diameter about one-sixth the length of 

 the disk and nearly equal to the width of the interorbital space. 



Hyoid and neighbouring parts of branchial arches not or only slightly 

 pigmented. 



Teeth as in the preceding species, except that the premaxillary teeth beyond 

 the vicinity of the symphysis become a single series. 



Second dorsal spine the longest, its length being at least three-quarters that 

 of the disk : the first dorsal spine is a bristle ending in a small tassel, the second 

 is a simple bristle, and the third which is little shorter than the second is fringed 

 throughout its length. Of the next three connected spines the first is the 

 longest, but the 2nd and 3rd are also of good length. Caudal a fourth the total 

 length (itself included). Pectorals narrow, pointed. 



Colours, mottled dark sepia to blue-black. 



Only one of the pyloric caeca is large. 



Three specimens, the longest a little over four and a quarter inches long, 

 from off the Malabar coast 68 to 148, and 100 fathoms. 



This species is distinguished from L. indicus by the larger eye, the narrow 

 pointed pectoral fin, the long caudal fin, and the different form and length of the 

 isolated dorsal spines.

 fins — with slender tassels.
