Where the outer surface of the scale is preserved, it isseen to be distinctly radiated, and pectinated on the posterior margin. In general appearance this species, although belonging to the moreelongated group of the genus, is not so slender as Lepidotus pecti-natus or Lepidotus Deccanensis. Its most striking feature is theunusually large proportion of the head to the total length. Thispeculiarity serves to distinguish it from all the species hitherto de-scribed, and has suggested the propriety of the specific appellation. Lepidotus breviceps, Egerton. XII. fig. evidence of a second species of Lepidotus among the ichthyo-. 1854.] EGERTON—FOSSIL, FISH FROM THE DECCAN. 373 lites recently received by Colonel Sykes is pretty clear, although thespecimens affording it are deficient in many details. One specimenand its counterpart contain a head and a small portion of the body;another specimen shows the impression of the trunk as far as thebase of the tail; and its mutilated counterpart contains the base ofthe skull and the scales of the anterior and middle portion of thebody. With the exception of a few scattered rays, all the fins arewanting. The length of the fish, from the nose to the base of the tail, is 7inches, the greatest depth being 2\ inches. The head measures 1\inches, or less than one-third of the entire length. It will be seen,on comparing these dimensions with those of other species of Lepi-dotus, that this is one of the smaller species of the genus. In general form it very much resembles the American genusIschypterus; and indeed in si
