brane ; the caudal is large, ratber rounded, and formed of nine- 
teen rajs, of wbicb thirteen onlj are long ones ; ventrals formed 
of six rays, which are united to the anal by a membrane without 
rays ; the anal is formed like the dorsal, and has forty-one or 
forty-two rays ; the pectorals rather longer than the distance 
from the end of the snout to the posterior margin of the eye, 
and formed of eleven rays. 
This fish is common on the Melbourne Market, but rarely 
attains a foot in length. It is of an olive green, with large mar- 
bled blotches of a darker and brownish colour ; the lower side 
is w'hite, with its pectorals rather pink ; the eye is black, with an 
orange circle. 
It is esteemed for the table. 
Nota.' — Professor M‘Coy considers this fish, “Intercolonial 
Exhibition, 1866-67,” as being the Rhombosolea Flesoides of 
Dr. G-unthor ; but the description of this specie, “ Ann. and Mag. 
of Natural History,” 1863, p. 116, does not agree with it ; the 
numbers of the rays are very diiferent ; the bifurcation of the 
lateral line is not mentioned ; the dorsal also seems to begin 
too far behind to allow it to be placed wdth Mhomhosolea.
