Two specimens were sent by Mr. Krefft; they were collected at 
the Clarence River by James F. Wilcox, Esq., to whom science is in- 
debted for many valuable acquisitions from that country. 
I take this opportunity of remarking that Hyla aurea, Less., 
has the first finger opposite to the three others, and that therefore 
it ought to be referred to the genus Litoria. 
HALOPHILA PLATYDACTYLA. 
This species is very similar to H. vitiana, Bibr., but distinguished 
by the very broad terminal disks of the fingers, which are as large 
as the tympanum. In the form of its head it agrees with the other 
species mentioned; the tympanum is not quite half as large as the 
eye; the choanz and openings of the Eustachian tubes are small, 
and the minute vomerine teeth form only a very short oblique series 
behind the choanze. The skin is perfectly smooth. The first finger 
is shorter than the others. The length of the body is more than 
the distance between vent and heel. Toes with a rudimentary web, 
and with the terminal disks much smaller than those of the fingers ; 
the third toe is longer than the fifth; metatarsus with two minute 
tubercles. Uniform brownish violet above ; light brownish below. 
Length of the body 16 lines, of the hind limb 22 lines, of the 
fourth toe 7 lines, of the fore limb 113 lines. 
The locality where this species has been obtained is not known, 
but it is probable that it came from one of the Feejee Islands. 
MISCELLANEOUS. 
Notice of a new Genus (Silurana) of Frogs we om West Africa. 
By Dr. J. E. Gray, F.R.S. & 
Mr. Moors, of the Free Museum, Liverpool, ne kindly sent to me 
for examination some young Frogs and their larve which he has 
lately received. They are peculiar for having a very long beard, like 
the cirri of a Silurus or Cat-fish, on each side of the mouth. The 
larva has the flat head and much the appearance of that genus of fish. 
Sinurana (Fam. Dactylethride). 
The mouth with an elongated beard on each side, at the angle of 
the gape. ‘Tarsus with a spur at the base of the first toe; the rest 
like Dactylethra. 
The larva with a very broad flat head, and a very long beard at 
the angle of the mouth on each side: this beard in the larva is 
as long as the body; it is shorter and thicker in the specimens 
which have their fore and hind feet well developed but still retain 
their tail. The tail is compressed, finless above, but with a broad, 
well-developed membranaceous fin extending the whole length of the 
lower edge.
