lower extending along middle of side of tail. A single dorsal. Ventral 

 rays 4. 



Pharopteryx corallicola (Bleeker). 

 Padang, Sumatra (A. C. Harrison and Dr. H. M. Hiller). 



Rypticus xanti (Gill). 



Head 2f ; depth Sf; D. HI, 25, i; A. 16, i; scales about 103 in lateral 

 line to base of caudal and 8 more on latter; pores about 64 in lateral 

 line to base of caudal; about 13 scales in a vertical series between base 

 of second dorsal spine and lateral line; about 27 scales in a vertical 

 series between origin of spinous anal and lateral line; mandible ^ in 

 head; second dorsal spine 4; fifteenth dorsal ray 2^; eleventh anal ray 

 2^; least depth of caudal peduncle 3; caudal 1|; pectoral 1|; ventral 

 SI ; snout 3i in head measured from tip of upper jaw ; eye 5^ ; maxillary 

 2J; interorbital space 2 in snout. Body long, rather slender, com- 

 pressed and lower profile a little more convex than upper. Head 

 compressed, and upper profile more or less straight from tip of snout 

 to dorsal. Snout broad as long, surface convex. Eye circular, high 

 and about first third in head. Mouth obliciue, with robust mandible 

 well protruding. Lips fleshy. Maxillary broad, reaching posterior 

 margin of eye and its distal expansion | of eye. Rather broad bands 

 of teeth in jaws, and some of inner a little enlarged pointed though not 

 depressible. Bands of fine teeth on vomer and palatines. Tongue 

 long, slender and free. Nostrils near together in front of snout a little 

 above, and anterior in a short cutaneous tube. Interorbital space 

 rather narrowly convex. Preorbital with entire margin convex. Margin 

 of preopercle with 3 spines, lowest largest and uppermost smallest. 

 Opercular spines 3, median most posterior, closer to uppermost, and 

 lowest most anterior. Gill-rakers viii, 1 + 8, vii, short, robust, and a 

 little longer than filaments or half of orbit. Scales small, smooth, 

 and in more or less slightly wavy longitudinal series crossing lateral 

 line behind. Small scales on bases of fins. Head covered with small 

 scales, except on lips and maxillary, and about 24 series on cheek. 

 Lateral line convex at first under spinous dorsal and then sloping 

 gradually down, of simple tubes. Spinous dorsal inserted near first 

 third in entire length of fish, and second spine longest. Rayed dorsal 

 separated (though joined by membrane) by a space about same as 

 space between last 2 dorsal spines, origin of fin midway in length of 

 body and posterior fourth of fin highest with convex edge. Anal 

 inserted midway between origin of pectoral and base of caudal and 

 most of fin more or less equally high. Caudal rounded. Pectoral 

 about I to anal and median rays longest. Ventral inserted midway
