length; and Plate V. shows G. postvectis, 6.35 in.; G. robinsonii, 8.2 in.; and G. fasciatus, 8 in.—total lengths. The drawings of the fishes are all reduced to the same length, for greater facility in comparisons. I must apologize for extending my literary matter on the subject to such length, but without doing so it was impossible to bring the various points of difference or resemblance under easy inspection.
