Polyipnus unispinus; after Schultz, 1938. characteristics; slightly shorter preopercle spine; and relatively larger eye. The single specimen from tlie Pacific (SIO 60-236-101) appears slightly different phenotypically from the Indian Ocean forms. These two populations should be further examined when such material is available. Description. D. 14-15; A. 16; P. 13-14; gill rakers 18-21; vertebrae (33). Largest specimen less than 50 mm SL. body narrow

Polyipnus unispinus; after Schultz, 1938. characteristics; slightly shorter preopercle spine; and relatively larger eye. The single specimen from tlie Pacific (SIO 60-236-101) appears slightly different phenotypically from the Indian Ocean forms. These two populations should be further examined when such material is available. Description. D. 14-15; A. 16; P. 13-14; gill rakers 18-21; vertebrae (33). Largest specimen less than 50 mm SL. body narrow, tapering into narrow caudal peduncle; its greatest depth less than length of subcaudal photophore group; eye relatively small, orbital diameter greater than six times into SL; post-temporal spine long, about one-half the diameter of orbit (or greater); dorsal spine short; preopercle spine short, narrowly triangulate; abdom- inal keel scales smooth, not extending far beyond body margins; subcaudal ^Dhoto- phores spaced apart (about width of a photophore between them), distance be- tween subcaudal and anal photophores about the same as length of one of the former; supra-anal raised only slightly above anals, with first supra-anal higher than second; supra-abdominal photophores in an oblique straight line; jaws medium; teeth minute; definite vomerine teeth present; gill rakers long, spinose; in pre- servative, pigment dark dorsally with broad, dark bar reaching to or near mid- line; dark pigment spots along trunk midline with pigment striations radiating from them; dark pigment above ventral photophores. Holotype: measurements (mm): SL BD , JL , CP ; mcristics: GE 19, D 14, A 16; anal photophores 11; name:] from the Marathi word "omphus," roughlv translated as "; Distribution (Fig. 63). Extremely dis- junct range; known from a few specimeni north of Madagascar in the Indian Ocear and from a single capture in the Centra Pacific north
