MlXOPHYES FASCIOLATUS. 



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 choanse, 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 numerou.i 

 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 

 Clarence River ; the following are the dimei\sions of an adult 

 female: —

Habit as in Camariolius varius, Peters, but with the snout longer 

 and more pointed ; the canthus rostralis is rather distinct between 

 eye and nostril, and is strongly deflexed in front. Upper parts 

 smooth, the lower coarsely granulated. Eye rather large, not much 

 shorter than the snout. Tongue narrow, ovate, entire behind ; vo- 

 merine teeth none, but there is a short, scarcely perceptible osseous 

 ridge in front of the orbital groove. Toes not fringed ; tarsus with 

 a longitudinal fold of th*e skin ; metatarsus with two minute tubercles.
