tralian specimens, and that the learned doctor might hare come 
to a more simple and natural conclusion, if he had admitted that 
he was uniting, under the same name, several very distinct 
species. 
OSTEOGLOSkSID^ 
“ Body covered with large hard scales, composed 
of pieces like mosaic ; head scaleless, its integuments 
nearly entirely replaced by hone ; lateral line com- 
posed of wide openings of the mucus-duct. Margin 
of the upper jaw formed hy the intermaxillaries 
mesially, and hy the maxillaries laterally. The 
dorsal fin belongs to the caudal portion of the verte- 
bral column, is opposite and very similar to the anal 
fin ; both approximate to the rounded caudal — with 
which they are abnormally confluent. Gill-openings 
wide ; pseudobranchige none ; air-bladder simple or 
cellular. Stomach without csecal sac ; pyloric ap- 
pendages two. 
“ Large fresh-water fishes of the tropics.” 
The genus Osteoglossus, which composes this family, was esta- 
blished by Vandelli, on a sort found in the Amazon Eiver, and 
which I have also observed there ; another species inhabits Borneo 
and Sumatra ; and a third (Leichardti) has been found in Queens- 
land, and described hy Dr. Gunther. These are all tropical 
fishes, and it is not likely that this form will ever he found in 
the southern parts of Australia. 
CLUPEID^. 
“ Body covered with scales ; head naked ; barbels 
none. Abdomen frequently compressed into a ser- 
rated edge. Margin of the upper jaw formed by
