liorizontal; all of bony spines of head relatively short and stout; 

 depressiblo cardiform teeth mainly in three rows on mandible, inner 

 row longest; similar teeth of unequal size near symphysis of upper 

 jaw, mainly in two rows, a single series of 17 small nondepressible 

 teeth on premaxillaiy posteriorly, the teeth increasing in size from 

 before backward; a pair of strong canines on each side of vomer and 

 a row of 5 to 7 similar teeth on palatines; well-developed filaments 

 on edge of lower jaw and disk, angle of mouth and sides of head, body, 

 and tail; skin tliin, not tough. 



Dorsal spines plain bristles, excepting the third, which is scantily 

 fringed; first 1.80 in head, its base close to receding edge of lip; 

 second 2.23, close to first; third 1.34, longest, partly concealed at 

 its proximal end, its base being in vertical to posterior margin of 

 eye; fourth 4.37, slender, concealed for nearly a third of its length, 

 its base midway between tip of snout and base of caudal; fifth 5.90, 

 similar to fourth and close to it; dorsal rays subequal, except first

and last, wliich are slightly shorter; caudal nearly truncate, an outer 

 simple ray on each side; anal small, its origin under posterior third 

 of dorsal; ventrals small; pectorals 1.80, well developed, some of 

 posterior rays not discernible without dissection. 



Color in alcohol: Dorsal surface olivaceous or sepia, ventral sur- 

 face Ught gray, densely dotted wdth minute black points; fins dusky, 

 ventrals similar in color to ventral surface, pectorals similar to adja-

Type.— Cat. No. 70264, U.S.N.M., 29 cm. in length, taken with a 

 beam trawl at station 5505 (lat. 8° 37' 15" N.; long. 124° 36' E.), off 

 northern Mindanao, at a depth of 220 fathoms. 



This species is very close to L. miacanthus (Gilbert) from the 

 Hawaiian Islands. In the type and two cotypes of the Hawaiian 

 form the pectoral has 21 or 22 rays, while in the Philippine species it 

 normally has 16, the number varying from 16 to IS; the first dorsal 

 spine is grayish instead of black, and the filamentous flaps are fewer 

 in number and not as well developed.
