. Fig. 36. Young specimen of Stylophorus chordatus. (;< 2I.) Hob. Atlantic; West Indies; south of Galapagos Islands. In his diagnosis of this species Regan states that there are no pelvic fins, but an examination of the small specimen obtained by the ' Discovery' shows that these are present, and that each has the form of a single ray lying below the hinder part of the base of the pectoral fin. This is very fragile and is wanting on one side of the fish, and there is little doubt that these structures have been broken off in all the specimens previously studied. Order BERYCOMORPHI Family DI
