The preceding table indicates certain of those differences which distinguish O. sexradmtus from C. notatus, the snout being longer and the orbit FlG. 11. COELORHYNCHUS SEXRADIATDS. TlTE. The posteroventral angle of the subopercle is sharply produced backward (and slightly downward). The interorbital width is least above front of pupil; least suborbital width, (to ) in postor- bital. The maxillary subtends the anterior two-thirds of the orbital length. Bands of fine teeth occur on the jaws; the outer premax- illary series is not enlarged. Six branchiostegals. The gill-mem- branes form a narrow free fold across the isthmus. The anus is located near the origin of the anal fin, the interspace being contained (to ) times in the distance between the anus and the base of the outer ventral ray, which is contained (to ) times in the postorbital length of the head. The distance between the outer ventral ray and the isthmus is slightly shorter than the dis- tance between the anus and the ventral fin (slightly longer in one paratype). A narrow, darkly pigmented, naked fbssa, widening anteriorly, extends forward from the anus to between the front of the ventral Please note that these images are extracted from scanned page images that may have been digita
