series from gill-o]ieiiing below lateral line to base of caudal; in greatest 

 width of body 26 series of scales between ventral profile of body and 

 lateral line, and between latter and upper lateral line 16; snout 2^ 

 in head; eye equal to interorbital space. Length 7| inches. Two 

 examples. 



89. CynoglosauB borneensis (Bleeker . 



Head 4i; depth oj; D. 100; A. about 4, 82; caudal about 10; space 

 between tip of snout and up]:)er eye 2^ in head; mouth cleft 5; upper 

 eye 4\ in space to tip of snout; interorbital space 4^; about 81 scales 

 in lateral line, beginning count above posterior edge of gill-o])ening, to 

 base of caudal (scjuamation injured) ; Ijelow and in a median series 

 nearly So scales within same limits; 40 scales in a transverse series in 

 greatest width of body or 6 between ujjper profile and u))per l^ranch of 

 lateral line, 14 between latter and median branch, and 20 below. 



Body long, greatly com]:)ressed, sinistral and greatest depth falling 

 about first f in length. Tail tapering rather narrowly posteriorly. 



Head moderate, upper ]:>rofile a little more convex, though both 

 evenly rounded. Snout a little long, well compressed and profile 

 strongl}- convex. Eyes rather small, close together, and upper with 

 only I of its length in advance of anterior margin of lower. Posterior 

 margin of lower eye much further from posterior edge of gill-opening 

 than anterior margin of upper eye is from tip of .=inout. jMouth large, 

 cleft nearly horizontal. Teeth fine, small, sharp pointed, and in bands 

 only in dextral side of jaws. Sinistral side of jaws with a lal)ial fringe 

 of rather small ragged cutaneous flaps. Tongue thick and inconspicu- 

 ous. Upper nostril just al)out op])osite anterior margin of lower eye 

 in interorbital space, but nearer upper eye than lower. Lower nostril 

 just a trifle in advance of anterior edge of upper eye, close to gape of 

 mouth and in a short fleshy tulie. Interorl)ital space narrow, flattened 

 medianly, otherwise slightly concave. 



(Till-opening small, ascenfling about level with middle of lower eye, 

 and membrane forming a broad fold over narrow comjjressed isthmus. 

 Rakers none. Filaments aljout f length of mouth cleft. 



Scales ctenoid, small and crowded on anterior half of l)ody aufl 

 around its profiles, l^it l:)ecoming enlai-ged on posterior half, esi)ecially 

 medianly. Lateral system of mucous pores double along trunk, 

 median series begins neai- tip of snout and nuis direct to base of caudal, 

 while u|)per one is confluent at its origin with this, and again well be- 

 hind eye, by means of a downward or nearly vertical series. U])per 

 series then continues near and concurrent with ujiper profile-line till 

 tielow fifth ray of ca\idal, counting from caudal where it ascends on
