18 NEW PEDICULATE FISHES 
link between Antennarius and Pterophrynoides, agreeing with 
the former in the robust form, the completely isolated rostral 
spine, the fixed pseudobrachium, and the small ventrals ; 
with the latter principally in the smooth skin, (See p. 24 
infra for key). 
RHYCHERUS WILD, sp. nov. 
D. ui, 13: A.8: C. 9: P.10: V. 5. Cutaneous appen- 
dages simple or ramose, longest on the head. Depth of 
body 3; of the total length. Upper profile from tip 
of snout to origin of soft dorsal undulating, the concavity 
between the frontal and occipital spines, wide and deep. 
Length of head 1%, its width 2? in the total length. 
Mental tubercle small; length of maxillary about 
4 of that of the head, its distal extremity rounded and as 
wide as the eye. Snout 6} in the length of the 
head, 3: in that of the maxillary, and equal to the 
eye and the interorbital width. Rostral spine terminating 
in a pair of widely separated fleshy lobes, forming to- 
gether a crescentic appendage. behind which is a low broad 
petiolate flap. bearing on each side a criniform filament ; 
height of spine 2 of the length of the head ; it extends, when 
depressed, beyond the naked interspinous fossa; second 
spine } longer than the first, fringed, bearing near its ex- 
tremity a pair of lateral ramose filaments, and reaching back 
to the base of the occipital spine, which is similar, but 
shorter, and bears in addition a pair of median filaments, 
which are ciliated distally and more than half the length 
of the spine; height of spine 2} in the head, its tip 
somewhat dilated and _ papillose, reaching, when de- 
pressed, to the origin of the second dorsal. Length of second 
dorsal rather more than its distance from the tip of the 
snout and rather less than the head ; first ray shghtly pro- 
duced ; second and third normal ; middle rays (and probably 
the posterior) terminating in a long filament, the fifth* 
about 2 of the length of the fin ; the rays, when depressed, 
reach far beyond the base of the caudal. Anal fin origin- 
ating below the 9th dorsal ray, rounded, the middle ray 
the highest, 1' time the basal length, % of the highest dor- 
sal ray, and reaching a little beyond the base of the caudal ; 
* Our specimen is in bad condition, and most of the radial filaments 
are broken.
