Icichthys lockingtoni, drawing of a 390-mm specimen, from Parin, 1958. hind pectoral insertion, toothless palate, moderate scales covering opercles and cheek, 100 to 130 scales in the lateral line, and 50 to 60 vertebrae, distinguishes Icichthys from all other stromateoid genera. The name, a masculine noun, is from the Greek Hkoj, to yield, + Ixdv^i, fish, in refer- ence to the fish's flexible soft body. Description. Body elongate, maximum depth less than 25 per cent of the standard length except in small specimens; muscula- ture soft. Peduncle broad, compressed, of moderate length. Dorsal fin originating well behind insertion of pectoral fins, con- tinuous, a few very weak spines graduating to the rays, 39-43 elements in all. A mid- dorsal ridge preceding the fin. Anus at about mid-body. Anal fin originating slightly behind middle of body, three weak spines precede the rays, 27 to 32 elements in all. Median fins with compressed fleshy bases. Pectoral fin rounded, base fleshy. Pelvic fins small, inserting directly under insertion of pectoral fins, not attached to abdomen with a membrane, folding into an insignifi- cant groove. Caudal fin broad, slightly rounded or emarginate. Moderate cycloid scales with prominent circuli, not especially deciduous, covering bases of median fins. Lateral line slightly arched anteriorly, straightening out over anterior part of anal fin and extending onto peduncle; lateral line scales around 120. Skin fairly thick; subdermal canal system not well developed, pores very small. Head around 25 per cent of the standard length, its profile sloping and the pores not prominent. Top of head not scaled, naked skin not projecting back- ward over the nape. Eye of moderate size, no adipose tissue. Nostrils near tip of trun- cate snout, both round. Angle of gape ex- tending below eye. Premaxillary not pr
