This very distinct species was dredged by the Albatross at a depth 
of 1,105 fathoms, at station 5428 off eastern Palawan, at a bottom 
temperature of 49.7° F. It is known from the type-specimen only. 
(paradowxus, in allusion to its supposed doubtful position, in refer- 
ence to the group “Chalinura’). 
12. CORYPHAENOIDES DUBIUS (Smith and Radcliffe).

This species is apparently closely related only to C. wood-masoni 
(Alcock), an Indian species. The interdorsal space and the outer 
ventral ray do not differ in length in the type of @. dubius and in 
Brauer’s? specimens of C’, wood-masont. 
According to the system of measurements outlined previously by 
us,® the orbit in the type and only known specimen is contained 1.4 
times in the snout; 1.05 in interorbital width, 5 in head; the least in- 
terorbital width is contained 3 times in the head. The maxillary ex- 
tends beyond the vertical from middle of eye. The basal fourth of 
the second dorsal spine is smooth. The angle of the preopercular 
ridge is bluntly pointed. There are six branchiostegal rays. 
Measurements in hundredths of length to anus (150 mm.; total 
length to end of pseudocaudal, 425 mm.) ; length of head, 64; length 
of orbit, 13; least interorbital width, 13.5; least suborbital width, 9; 
distance between orbit and preopercular margin, 31.5; length of 
snout, 18; length of upper jaw, 21.5; depth of body, 45; width of 
body over pectoral bases, 30; distance between the center of anus and 
the base of outer ventral ray, 29; distance from base of outer ventral 
ray to isthmus, 29; height of second dorsal spine, 41; length of 
pectoral fin from base of second ray, 34; length of first pectoral ray, 
4; length of second pectoral ray, 27.5; length of outey ventral ray, 
44; length of second ventral ray, 238.
