art.2. FORMOSA AND PHILIPPINES FISHES—FOWLER AND BEAN, 7 
ZACCO PLATYCEPHALUS (Guenther). 
Head, 34 to 3%; depth, 34 to 34; D. m, 7, 1; A. 1, 9, 1; scales, 
47 to 50 in lateral line to caudal base and 3 more on latter; 8 scales 
above lateral line to dorsal origin, 5 below to anal origin; 22 to 24 
predorsal scales; snout, 34 to 34 in head; eye, 34 to 45; maxillary, 
2 to 22; interorbital, 3. 
Body compressed, deepest at dorsal origin, edges all convex. Least 
depth of caudal peduncle, 24 to 23 in head. Head well compressed, 
attenuate. Snout conic; length four-fifths its width. Eye ele- 
vated, hind edge midway in its length, little posterior in young. 
Mouth large, lower jaw included in upper, which slightly projects. 
Maxillary reaches eye center, to front pupil edge in younger. Lips 
firmly coriaceous. Interorbital very slightly convex. Suborbital 
chain broad, covers half of cheek to preopercle ridge. Opercle 
smooth. Gill-opening forward to hind eye edge, or slightly more 
advanced in younger. Gill-rakers, 3+8 short joints, about 5 in 
filaments, which are 14 in eye. Pharyngeal teeth, 1, 4, 5—5, 4, 1, 
hooked and with well-developed grinding surfaces. Scales little 
larger and narrowly imbricated on costal region. Very small scales 
on breast and belly anteriorly. Each scale with radiating apical 
striae 8 to 10, basal circuli fine. Axillary ventral scaly flap about 
5 in fin. Lateral line deeply decurved, slopes up along caudal 
peduncle side to caudal base medianly, complete, and simple tubes 
well exposed. Dorsal origin little nearer caudal base than snout 
tip, and depressed fin reaches about half way to former. Anal with 
second and third branched rays reaching back to middle of caudal, 
shorter in younger example, and origin of fin opposite depressed 
dorsal tip. Caudal deeply forked, lobes pointed and lower often 
slightly longer. Pectoral 14 to 12 in head, not reaching ventral. 
Latter inserted trifle before dorsal origin, not reaching anal, 14 to 
2 in head. 
Color in alcohol faded dull brown, little paler below. Dark narrow 
streak follows each row of scales on back. Leaden median line along 
vertebral axis from above ventral to caudal base medially. Fins all 
pale or dull brownish. Dorsal with median blackish blotch in each 
membrane. Caudal with grayish marginally behind. Nine examples 
from Koroton. September 1 to 15,1907. Hans Sauter. 
BARBUS SNYDERI (Oshima). 
Head, 3 to 32; depth, 22 to 24; D. u, I, 8,1, sometimes 7,1; A. m1, 5, 
I, sometimes 6,1; scales, 22 or 23 in lateral line to caudal base and 2 to 4 
more on latter; 5 scales above lateral line to dorsal origin, 2 or 3 below 
to anal origin; 8 or 9 predorsal scales; snout, 33 to 3% in head; eye, 
22 to 3; maxillary, 3 to 34; interorbital, 23 to 23. Barbels, 4, posterior
