The ribs are attached to parapophyses ;there are thirty-three vertebiae. Family Veliferidae. Vdifer, Schleg. Tribe 2. Taeniosojii. The very compressed body is elongated, and may attain a length of20 feet, with some ninety vertebrae. The dorsal fin is very long, and issupported by unjointed dermal rays. The anal is short or are present, but the ribs are more or less completelyreduced. Of the three pectoral radials at least two rest on the post-teraporal has become KiG. glesne, (From .Jordan and Ev^rniann.) Family Lophotidae. The pelvic fins, if present, are small, widelyseparated, and with five or six dermotrichs. The anus is near the hindend of the body, with a small anal fin just behind it. A long sj^inerepresents the first dorsal ray. Lo}}hotes, Giorna ; warm seas. Eumecichthyes, Regan. Family Trachypteridae. The pelvic fins are close together, butthe dermal rays may be reduced to one (Regalecus). The anus is about LA MPRIDIFORMES 477 half-way up the body, and the anal fin has been lost. The caudal tinhas disappeared in Begaleeus, but in Trachypterus is strangely modified,the dermal rays being separated into two diverging fascicles (Fig. 506). Trachypterus, Gouan (Fig. 506), and Kegalecus, Briinn (Fig. 505)—widely distributed.
