The least sub- orbital width is contained times in the postorbital ( to times in paratypes from 60 to 77 mm. to anus; to times in paratypes from 50 to 57 mm. to anus). The upper jaw extends from below the middle of the nasal fossa backward nearly to the vertical from the posterior margin of the orbit; length of upper jaw, ( to ) in head. The barbel is slender; its free length is con- tained ( to ) times in the postorbital. The cardiform teeth of the upper jaw form a band, the outer series of which is sometimes enlarged. The mandibular teeth form two series laterally, of which the outer series is irregular; anteriorly, near the symphysis, the teeth are so irregularly arranged as to form a narrow Fig. 7.—Coelorhynchus quincunciatus. Type. The characters of the sensory canals and of the structures con- nected with them, are essentially similar to those described for C. argentatus. The anus is located immediately before the anal fin; the distance from its center to the base of the outer ventral ray is contained ( to ) times in the head; its distance from the isthmus, ( to ) times. The distance between, the base of the ventral and the isthmus is contained ( to ) times in the head. The gland-like body lying in the body wall, along the midventral line, has the peculiar structure that it also possesses in the last species—the anterior dilation is supported by a slender rod connected with the pubic bone. P3doric caeca, 8 to 11 (4 specimens). Several specimens contained Crustacea of various groups in their stomachs, but one contained a Myctophid fish, probably Myctoplmm, belonging to the silvery pigmented or surface-pelagic type.
