Two specimens were sent by Mr. KreflFt ; 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 Liioria. 



Halophila platydactyla. 



This species is very similar to //. ritiana, 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 iialf as large as the 

 eye ; the choana; and openings of the Eustachian tubes are small, 

 and the minute vomerine teeth form only a very short oblique series 

 behind the chuano;. 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 1 1 1 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.

Notice of a new Gentu (Silurana) of Froffs/rom West Africa. 

 By Dr. J. E. Gray, F.R.S. &c. 

 Mr. Moore, of the Free Museum, Liverpool, has kindly sent to me 

 for examination some young Frogs and their laniK which he has 

 lately received. They are peculiar for having a very long beard, Hke 

 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. 



Silurana (Fam. DactylethricUe). 



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 Dactyletkra. 



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, finltss above, but with a broad, 

 well-developi d nicnibranaceous fin extending the whole length of the 

 lower edge.
