DESCRIPTION OF A SPECIES OF ELEOTRIS. B33) 
groups: one with fewer, the other with more than fifty scales on 
the lateral line. Among those with fewer, that is larger scales, 
is a subordinate group of peculiar form, having a remarkably 
broad and flattened head; this group also contains the largest of 
the species hitherto found in Australia. That from Rockhamp- 
ton, however, is considerably larger than its compatriots, and 
combines the broad depressed form of the one group with the 
small scales of the other. The following are its characters :—
