MEMOIHH OF TEE QVEENBLAED MUSEUM. 
maxillaries subvertical when retracted ; jaws weak, a])parently toothless, though 
the mandibular symphysis feels rough ; gill-rakers very slender, over 1 mm. long 
and strongly pectinate ; sixteen on lower limb of first gill-arch. 
Body very deep and much compressed ; ventral profile deeper and more convex 
than the dorsal profile, which is more evenly rounded. The type-specimen is denuded 
of scales, but there are traces anteriorly of a lateral line, which becomes obsolete below^ 
the soft dorsal fin, and some rather large scale-pockets on the thorax. De Vis noted 
the scales as ■' minutely granular.’’ Anterior portion of breast apparently naked. 
Dorsal and anal fins each preceded by a large procumbent spine ; third dorsal 
and anal spines with some inconspicuous serrations ; base of anal fins less than that 
of both dorsals ; pectorals damaged, but Avith the second ray thickened ; ventral 
spine 2 mm. long, rest of fin damaged ; caudal damaged, apparently foi'ked. 
The colour has now faded to brown \\ ith widely spaced dots on head and lower 
part of body ; a row of these dots corresponds to the underlying interhaimals of tho 
anal rays. De Vis described the colours as : “ ColoTir above the vertical line silvery 
grey, above it a median black longitudinal streak ; between this and the dorsal 
numerous oblique streaks descending backw ards and on its lower side backwardly 
ascending streaks from a lower longitudinal stripe defining the vertebral line above.’’ 
Apparently no black blotch on dorsal fin. 
Described from the holotype of Equula profunda De Vis, a damaged and semi- 
macerated specimen, 37 mm. in standard length or about If inch, in total length.. 
The dorsal spines have become detached, and the specimen is in such poor condition 
that it has not been figured. 
Locality. — Cape York, North Qxieensland. 
Relationships. — Secidor profundus is apparently a valid species distinct from 
S. ruconius (Buchanan-Hamilton) and S. insidiator (Bloch), Avith Indian specimens 
of which, from Day’s collection, I have compared it. Australian specimens identified 
as Equula interrupta^ Cuv. & Val. may be Secutor profundus. 
Forty-four specimens (Austr. Mus. Nos. lA. 4911-4915, 4921-4922 ; E. 2525- 
2527, 2673-2674), trawled off Bowen, Queensland, by the ‘‘ Endeavour,” are 
apparently referable to this species.
