CHARACINIDAE FROM VENEZUELA—SCHULTZ YAH) 
The following counts were made, respectively: Dorsal rays i, 8 
(ii , 8); anal ii, 16 Gui, 16); pectoral i, 11-1, 11 Gi, 1141, 11); pelvici, 7-1, 
7 G, 71, 7); branched caudal fin rays 17 (17); gill rakers on first gill 
arch —— (5+9); number of scales from upper edge of gill opening to 
midcaudal fin base 36 (86) ; scales above lateral line 5 (5); below lateral 
line to pelvic insertion 3 (3); predorsal scales to tip of supraoccipital 
process 11 (12), and 2 (2) scales along side of that process; number of 
teeth in outer row of premaxillary 4—4 (8-4) and inner row 4-4 (4-4); 
teeth on maxillary 2-8 (2-2). Additional counts are recorded in 
table 24. 
Body only a little compressed, the greatest depth usually 3.1 to 3.3, 
head 3.5 to 3.7, in standard length; snout 14 in eye and about 4.0 to 
Ficure 51.—Bryconamericus deuterodonoides euryodous, new subspecies: Holotype, 
U.S.N.M. No. 121437, 33.2 mm. in standard length. (The last dorsal ray has two 
separate bases and not a single one as shown in the drawing.) 
4.2 in head; interorbital about equal to eye and 3.0 to 3.2 in head; 
dorsal and ventral profiles about equally arched; predorsal and pre- 
ventral areas rounded and normally scaled; supraoccipital process 
short, its length about 8 times in distance from tip of this process to 
dorsal origin; snout blunt, rounded, the lower jaw slightly included, 
the outer row of premaxillary teeth scarcely showing; mouth when 
closed on a level a little above lower edge of pupil; rear tip of the 
maxillary extending to a vertical through front edge of pupil; ventral 
edge of second suborbital in contact with preopercle below; lateral 
line complete, a little decurved anteriorly; gill rakers short-pointed; 
teeth all 3- to 5-pointed, with middle denticle longest and strongest, 
except those on the maxillary, the teeth on the latter usually have 
about 6 denticles of nearly equal size; anal origin under rear edge of 
dorsal fin base; adipose origin over base of last anal ray; dorsal origin 
almost an equal distance between tip of snout and midcaudal fin 
base; pelvic insertion much closer to base of last anal ray than snout
