strong spines. The author has compared it with exam¬ 
ples of ccelorhynchus from the Mediterranean, and also 
from Madeira, both in the Society’s museum, whose scales 
are totally different. None of these examples have the 
first dorsal ray serrated, as it is stated to be by writers 
who have described and figured the Greenland and Ice¬ 
land Macrourus rupestris; yet Cuvier states that he has 
ascertained the identity of the latter with the Mediter¬ 
ranean fish. The first dorsal ray of L. australis is also 
smooth. There are sixty-seven vertebrae, of which four¬ 
teen are abdominal. The collection contained three 
specimens. 
The subject is resumed in a paper read before the 
Zoological Society, March 10th, 1840 ; and the author 
describes a Dajao, which differs from the three known 
mullets of Australia in many particulars, and from all 
the Mugiloidece described in the Tlistoire des Poissons , 
in the greater number of rays of the anal fin, as well as 
in the combinations of other characters. The only Dajao 
mentioned in the work referred to, is an inhabitant of the 
mountain streams of the Caribbee Islands ; while the 
Van Diemen’s Land one has been found only in the sea : 
but perhaps both are anadromous. The rough plates on 
the palate and vomer of some acknowledged typical mul¬ 
lets assimilate their dentition greatly to that of the 
Dajaos ; and the present species approaches the ordinary 
mullets in the form of the orifice of the mouth, while its 
palatine and vomerine teeth are nearly as large as those 
on the jaws. It is prized as an article of food.

The author next remarks that, of four Labri in the col¬ 
lection, two species, comparatively little ornamented, are 
furnished with six gill rays, while the other two, more
