Diagnosis
ReferenceDiagnosis
D. S. Jordan and J. Z. Gilbert 1920Body
rather elongate, compressed, the back straight, scarcely arched, with a very large head, 3 in length, the depth about 4*4 ; mouth large, the cleft extending beyond eye ; larger than in SEBASTOSOMUS and ROSICOLA ; lower
jaw prominent, with bands of even, pointed teeth.
Vertebrae 24 (25), large, mostly longer than deep, strongly grooved;
neurals and hsemals strong; interneurals long and strong, expanded or
dagger-shaped at base, especially anteriorly, one and sometimes two pos- teriorly between each pair of neurals. Interhaemals small, slender, and
very oblique except the second, which is robust and very long, half head ; two or three set irregularly between each pair of haemals. Dorsal con-
tinuous, deeply notched, its rays XII, I, 13. Anal rays III, 6, or possibly 7, the second spine very long and strong. Pectorals broad, rounded.
unsymmetrical. Caudal broad, subtruncate, the hypural plates large, about two on a side, with an open median split which separates the caudal rays in the skeleton.
Cranium unknown ; armature of head and squamation of body, with character of gill rakers, undetermined. Among living forms the species in question is certainly nearest typical SEBASTODES, but the second anal spine and its interhaemal are greatly enlarged.
