MEMOIRS OF THE QUEENSLAND MUSEUM. 
Teeth are present on the pterygoids, and the surface of these bones is 
covered with small tubercles. The teeth are short and stout on the entopterygoid, 
and slenderer on the fused ectopterygoid and palatine. The pterygoids greatly 
resemble the corresponding bones in Scleropage-s leichardti and differ from the 
other living genera (see Ride wood 1905). Teeth are not present on either the 
parasphenoid or the vomer. 
Remarks. — Fossil remains of Osteoglossids are very rare, the only other 
occurrences being the well-known Phareodus spp. in the Eocene Green River 
shales of Wyoming, Bryehaetus from the London Clay (and possibly the 
Oligocene of Germany (Zotz, 1928) and Phareodus from the lower Tertiary of 
Sumatra. The latter is an extremely interesting recent discovery, and Dr. de 
Beaufort, in a personal communication, states that the Osteoglossids from 
Sumatra (one large specimen and some smaller ones) are “ very near 
Dapedoglossus ” [Phareodus]. 
Eastman (1917, p. 288) states of Phareodus acutus , “ Its primitive 
characters are evident, and among surviving genera the resemblance is closest 
to Heterotis of tropical Africa.” I believe, however, that as Boulenger held 
(1922, p. 55 7) it is closest to Scleropages. In support of this the resemblances 
in the cranial osteology, which extend to the opercular series, post orbitals, 
jaws, pterygoids, and cranial roof, as well as the presence of the elongated first 
pectoral ray and the general shape of the body, are notable. As is the case 
with Epiceratodus , it seems that the fish living in Queensland represents a 
less differentiated survival than any other, of a previously widespread family.

(Plate XX ; Text-figures 8-9) 
Locality. — Redbank Plains. 
Material. — [RP/N]. Five specimens preserved as moulds in limonitic 
mudstone. Holotype, No. 4, a, b. 
Description. — Small fishes, estimated maximum known length about 
0-2 metres. The dorsal and pelvic fins are inserted slightly behind the middle 
of the fish, the dorsal just behind the pelvics ; the caudal is excavated. The 
head is pointed, the mouth ventral, and the head and opercular apparatus 
are contained about four times in the total length of the fish to the tip of 
the tail. The length of the head exceeds the maximum depth of the body.
