Family OPISTHOGNATHID^E. 
Genus TANDYA nov. 
Orthotype, Ognsihognathus maculatug Alleyne & Macleay. 43 
Maxillary extending well beyond hind margin of eye, its distal extremity 
truncate. Teeth of outer row in jaws larger than the others, except for an 
inner row of strong teeth in the lower jaw. Scales cycloid, of moderate size, 
in more than sixty and less than eighty transverse rows on the body. They 
extend over shoulders but leave naked patches on each side of spinous dorsal 
and above pectorals. Twelve dorsal spines, all simple. Caudal rounded. 
Gill 44 made a new genus, Qnathypops, for [Opisthognathns] maxillosus Poey 
and 0. microps Poey, “ with moderately small scales and maxillars passing 
little beyond the eyes,” and his name has been employed for the Australian 
species to be noted hereunder. The logotype of Gnafliypops is the Cuban 
Opisthognathiis maxillosus Poey, 45 as selected by Jordan & Gilbert 46 who 
redescribed the species. It differs from Australian forms in having eight dorsal 
spines and a shorter maxillary. 
Besides the genotype, my new genus includes two other Australian 
species ; Opisthognaihus darwiniensis Macleay 47 from Port Darwin, and 0. 
inornatus Ramsay & Ogilby 48 from Derby, Western Australia. These must 
now be known as Tandya darwiniensis and Tandy a inornata respectively. The 
type of the latter species is in the Australian Museum (I. 841) and was figured 
by McCulloch. 49 
The typo of Batrachus jmnciatulus Ramsay 50 is also in the Australian 
Museum (/. 1254). This species, described from Torres Strait, is synonymous 
with Tandya maculata. 
Family BLENNIIDrE. 
Several well-differentiated species have been described as belonging to 
Blennius Linne, but obviously have no close relationship with that European 
genus and would better be regarded as the orthotypes of new genera as 
follows 
Blennius intermedins Ogilby 51 may be called Pictiblennius ; this new genus 
also includes Blennius tasmanianus Richardson. 52
