SICYOPTERUS 307 



Sicyopterus cynocephalus BLEEKER, Versl. Med. Akad. Amsterdam 



II 9 (1876) 275. 

 Sicydium parvei (non Bleeker) GUNTHER, Cat. Fishes Brit. Mus. 3 



(1861) 94. 



Dorsal VI, 1-10 or 11; anal I, 10 or 11; there are 75 to 80 

 scales in a longitudinal series and about 17 in a transverse 

 series. 



The depth about 5 times, the head 4.5 times in length; the 

 width of head rather greater than height and about f of length ; 

 the diameter of eye 6 times in head and half the interorbital 

 space; the posterior angle of maxilla beneath posterior margin 

 of eye ; the upper lip has a very slight median cleft, with a small 

 papilla beneath it ; a row of small papillae on gum beneath 

 upper lip; the horizontal teeth of lower lip conspicuous; the 

 scales on sides of body larger than those on caudal peduncle 

 and much larger than those on anterior part of body and occi- 

 put; the first dorsal higher than body, the third spine produced 

 into a short filament; the second dorsal not so high as body; 

 the caudal contained 4.33 times in length; the pectoral longer 

 than head. 



The color above deep violet or greenish violet or dark green, 

 below whitish or yellowish, with six or seven more or less in- 

 distinct, broad, oblique, brownish or darker crossbands ; a brown 

 spot below eye ; the dorsal and anal fins orange, the second dorsal 

 sometimes with large, regularly disposed brown spots on rays; 

 the anal has a broad violet or brown margin; the caudal olive 

 with the superior and inferior edges yellow ; the pectoral yellow- 

 edged. 



The above description is compiled, as I have seen no authentic 

 specimens. Boulenger listed this species among those collected 

 by Whitehead in Palawan. It is an East Indian species, occur- 

 ring from Sumatra to the Moluccas, and is "found in fresh wa- 

 ters 3000 feet above the level of the sea." According to Bleeker 

 it attains a larger size than does any other species of the genus ; 

 his largest specimens were 160 millimeters in length.

 posterior part, the dorsal and ventral profiles nearly parallel,
