20 NEW PEDICULATE FISHES 
the tip of the snout and terminating in a simple tentacle ; 
frontal and occipital spines shorter and stouter than the 
rostral, latter inserted immediately behind eye, widely 
separated, without intervening naked fossa; all the 
fin-rays simple; second dorsal high, with 11 slender 
rays, connected by delicate, diaphanous membrane, and 
deeply cleft at the extremity : anal fin with 7 rays, similar 
to second dorsal, and inserted entirely or almost entirely 
behind it : caudal fin long and rounded, with 9 rays ; caudal 
peduncle free: pseudobrachium almost wholly free and 
mobile ; pectoral fin long and narrow, with 7 rays: ventrals 
moderate, pointed, with 5 rays, inserted behind the oc- 
cipital spine. (rafe’s, extending ; «ap7os, wrist : in reference 
to the greatly elongated actinosts). 
East Coast of Queensland (Port Curtis). Two species. 
In the length and mobility of the pseudobrachium this 
genus is only approached by Brachionichthys, from which, 
however, the position of the gill-openigs widely separates it.

dages in small number, simple, longest on the chin, throat, 
and corner of the mouth. Depth of body 1% in the 
total length. Upper profile from tip of snout to base 
of occipital spine gently, thence to origin of second dorsal 
strongly convex. Length of head 12, its width 33 in the 
total length. Mental tubercle small; maxillary extending 
to below the posterior border of the orbit, its length 24 in 
that of the head, its distal extremity rounded, and about 
half as wide as the eye. Snout 6 in the length of the head, 
33 in that of the maxillary, 14 in the diameter 
of the eye, and equal to the interorbital width. Rostral 
spine & of the head, extending, when depressed, midway 
along the interdorsal space ; frontal spine 4 of the rostral, 
curved, extending, as also does its membrane, to the base of 
the occipital spine ; occipital spine similar to but much longer 
than the frontal, bearing anteriorly a long median and sub-
