U.S.N.M. no. 98830 (field parchment tag 1743), a specimen 87 mm 

 in standard length; station D. 5112, off Sombrero Island, southern 

 Luzon, latitude 13°48'22'' N., longitude 120°47'25" E.; January 17,

 in standard length ; same data as no. 98830. Figured example. 



U.S.N.M. no. 98832 (field parchment tag 1744), a specimen 90 mm 

 in standard length ; same data as no. 98830. 



B.O.C. no. 518b, a specimen 82 mm in standard length; taken in 

 484 fathoms north of Glover Keef , British Honduras ; April 20, 1925 ; 

 S. Y. Pawnee. Paratype of Grammicolepis squamilineatus Mowbray. 



Dorsal fin with a tiny, scarcely evident first spine ; a main serrated 

 spine, which is long and provided with a filamentous tip in the yomig; 

 a thinner serrated spine; three soft, unarticulated spines; and 28 or 

 29 articulated rays. Anal with a long, serrated first spine, nearly as 

 long as, or longer than the head, its tip filamentous in the young; a 

 second shorter serrated spine; and 27 to 29 articulated soft rays. 

 Pectorals with 14 rays. Color silvery, the younger specimens with 

 round dark spots, placed irregularly. 



This species differs decidedly from Grammicolepis in the lesser 

 extent of the changes in proportions and other external features dur- 

 ing growth. The younger specimens have filamentous tips to the 

 second dorsal and first anal spines, which are lost with growth, and 

 the relative length of the second dorsal spine decreases. The body 

 is deeper in the young than in the adult, but even the latter retains 

 a very deep form. The high, pointed arch of the lateral line and the
