Larvae of Oxylebius pictus, Zaniolepis sp., Ophiodon elongatus, Hexagrommos stelleri, H. decagrammus, H. lagocephalus, H. octogrammus, and Pleurogrammus monopterygius are described and illustrated from field collections which were supplemented by laboratory reared specimens of some species. Larvae hatch at a rather large size (3-9 mm), are heavily pigmented, and undergo direct development to an epipelagic prejuvenile stage. Larvae or the five genera are separable on the basis of body shape, pigmentation, and meristic characters. Larvae or the four species of Hexagrammos, which are quite similar in appearance, are separable on the basis of a combination of several pigmentation characters. Developmental evidence indicates that Oxylebius and Zaniolepis are similar to each other and are more similar to presumed primitive coUids than the other included genera. Ophiodon is dissimilar to the other four genera. Pleurogrammus and Hexagrommos have similar appearing larvae. Among the species of Hexagrammos a progression or increasing larval pigmentation can be seen from H. stelleri to H. decagrammus, H. lagocephalus, and H. octogrammus. (PDF file contains 50 pages.)
