Maxillary with a small anterior expansion ; a supiamaxillary ; canines slender, barbed, forming a regular series in the lower jaw. Skull considerably expanded behind the narrow interorbital region ; parietals meeting above supra- occipital; posterior temporal fossae not roofed ; lateral ethmoids separated by an interspace; suborbitals ossified. A single laminar postcleithrum ; cleithrum expanded below. 52 ver- tebrae; ribs on short processes. Dorsal fin short. Ffc. A. B. A. Pectoral arch of Evermanella hyalina ; from within. B. Pectoral arch of Omosudis loioii; external view, with the coracoids and radials not exposed. ptte, post-temporal; cl, cleithrum ; sel, supracleithrum ; pel, pel', post- cleithra; sc, hypercoracoid; cor, hypocoracoid ; r, radials ; p, fin- rays. Scopelarchus, Alcock, seems to be more primitive than the other genera. As described and figured it has the head, mouth, teeth, &c. of Evtrmanella, but the dorsal fin is more advanced, there are traces of small scales in addition to the large scales of the lateral line, and the eyes, described as having the visual axis superior rather than lateral, are probably not formed as in Evermanella. Neosudis, Casteln., may pertain to this family. In Evermanella, Fowler (Odonto- stomus), and JJissoma, Brauer, the eyes can look upwards or outwards, being lodged in a vertical pocket which is covered externally by a transparent membrane. The skeletal characters given are those of an example of Evermanella Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original London, Taylor and Francis, Ltd
