BULLETIN FLORIDA STATE MUSEUM varies from 8.5 to 10% SL (X = 9.1%, n = 12). Twelve pectoral-fin rays present in all larvae. Larvae exhibit the following pigment pattern in alcohol: membrane between lower 6 pectoral rays pigmented to tips, membranes between sixth-seventh and seventh-eighth rays pigmented only on inner half and fourth respectively, with outer portion of membrane transparent; mem- brane covering brain with several large pigment spots; two pigment spots on either side of tip of upper jaw, immediately anterior to oribital margin; a pigment spot at dorsal edge of each opercle at upper angle of gill opening. Table 6-Matrix of covariance comparisons of regression equations (Table5) for number of mandibular teeth between different populations of Chasmodes (P<0.001; see Table 3 for explanation of abbreviations). 0 = coincident regression lines; = noncoincident but parallel lines; + = noncoincident and nonparallel lines.

Populations of C. b. bosquianus have significantly shorter maxillary lengths than populations of C. b. longimaxilla (Table 7). No consistent statistical differences were obtained for the number of mandibular teeth between C. b. bosquianus and C. b. longimaxilla populations (Table 6). Two popula- tions of C. b. bosquianus (Chesapeake Bay area and Marineland) have significantly fewer mandibular teeth than all populations of C. b. longimax- illa. The North Carolina population of C. b. bosquianus significantly differs in number of mandibular teeth from only one population (Laguna Madre) of C. b. longimaxilla. Comparisons of the number of mandibular teeth between other populations of the two subspecies did not show significantly different regression equations for number of mandibular VOL. 29, NO. 2
