 DIAGNOSIs.-Chasmodes bosquianus bosquianus differs from C. b. lon-
gimaxilla in having a shorter maxillary length (X = 14.9 vs. 17.3% SL; Fig. 3,
Table 4), and in having a total of 1-6 small canines (Table 1) in addition to
enlarged canines on upper pharyngeals, whereas C. b. longimaxilla has 0-5
(most specimens examined over 40 mm SL with 0-1). Gill rakers 11-13
modallyy 12) for C. b. bosquianus vs. 9-12 modallyy 11) for C. b. longimax-
illa (Table 1).
 DEscRIPTIoN.-(See also Table 1). Maxillary length expressed as per-
cent of SL 12.5-18.5 (X = 14.9%, number [n] = 189; Table 4); number of
mandibular teeth varies ontogenetically, number increasing with increased
size (Fig. 4); mandibular pores 4 to 6 (X = 4.3, n = 169; Table 1); enlarged
upper pharyngeal teeth 6 or 7 on each side; branched caudal-fin rays 0-10;
small upper pharyngeal teeth 0-4 on each side (Table 1); enlarged lower
pharyngeal teeth 4 (n = 4); maximum size approximately 80 mm SL.
 Twelve larvae (5.4 to 7.3 mm SL) have 5 to 7 spines radiating posteriorly
from preopercle, with spine at angle of preopercle enlarged. Small man-
dibular teeth range in number from approximately 8 to 12. Maxillary length
