4. Tuirp ConTRIBUTION TO OUR KNOWLEDGE OF BATRACHIANS 
FROM AuSTRALIA. By Dr. A. GUNTHER. 
(Plate VII.) 
The following is a continuation of two other papers treating on the 
same subject ; they were published in the ‘ Annals and Magazine of 
Natural History,’ 1863, p. 26, and in the ‘ Proceedings’ of this 
Society, 1863, p. 249. 
MrxopuyeEs (g. n. RANIDARUM), 
Habitus as in Rana, the head being broad and large; legs of mo- 
derate length. Tongue circular, not notched behind; vomerine 
teeth in two series ; lower jaw without tooth-like apophyses. Open- 
ings of the Eustachian tubes narrower than the choane ; tympanum 
distinct. Fingers free, none opposite to the others; interdigital 
membrane between the toes well developed; fifth toe moveable to 
its base ; a long, compressed, subsemicircular tubercle at the meta- 
tarsus. Male with a single subgular sac, which is not visible exter- 
nally. 
Mixopuygs Fasciotatus. (Pl. VII. fig. 1.) 
This Batrachian approaches the true Frogs more closely than any 
other known from the Australian region ; its habitus is that of Rana, 
but the head is disproportionally large and broad. The snout is ob- 
tusely rounded, with the canthus rostralis gradually descending in a 
gentle curve, and with the loreal region obliquely flattened. The 
nostril is scarcely below the canthus, midway between the eye and the 
end of the snout. The eye is large, prominent. Cleft of the mouth 
very wide, much broader than long. The vomerine teeth are in a 
nearly straight line, between the anterior angles of the choane; the 
two series being separated in the middle by a narrow space. Two 
long slits on the side of the tongue lead into the subgular sac. The 
tympanum is nearly as large as the eye. With the exception of a 
very slight fold above the tympanum, the skin is perfectly smooth. 
Fingers tapering, rather slender. The length of the body equals 
the distance between vent and heel, but it is much more than the 
length of the remaining foot. Toes two-thirds webbed, so that the 
three outer phalanges of the fourth toe remain free. 
Upper parts brownish olive, with a darker cross band between the 
hinder half of the superciliaries. A black band runs along the can- 
thus rostralis, widening on the foremost part of the snout below the 
nostril, and is continued behind the eye, above the tympanum ; sides 
of the body with round brown or black spots ; legs with numerous 
black cross bands, which are most distinct on the hinder side of the 
fore legs and on the anterior side of the hind limbs. Lower parts 
uniform white ; throat of the male brownish. 
Specimens of this Frog have been sent by Mr. Krefft from the
