DESCRIPTION OF A SUPPOSED NEW CYSTIGNATHOID 



FROG. 



By J. J. Fletcher. 



Crinia froggatti, sp.n. 



Vomerine teeth in two small groups behind the choanse. Snout 

 rounded, as long as orbital diameter ; nostril equally distant from 

 the eye and the tip of the snout ; interorbital space broader than the 

 upper eyelid ; tympanum hidden. First linger hardly half as long 

 as second ; toes not fringed ; subarticular tubercles indistinct ; an 

 inner small metatarsal tubercle ; no tarsal fold. The tibio-tarsal 

 articulation of the adpressed limb reaches nearly to the eye. Skin 

 above with small scattered tubercles on the back ; beneath smooth 

 except for a triangular space on the lower and hinder sides of the 

 thighs on each side of the median line which is very granular. 

 Colour (a) of spirit specimens : — greyish above with blackish 

 spots ; a blackish band on each side from the tip of the snout 

 through the eye to above the shoulder, frequently interrupted ; a 

 blackish transverse patch between the eyes sending off posteriorly 

 a little on either side of the median line a ragged slightly divergent 

 narrow longitudinal stripe at length becoming broken up into 

 spots, sometimes the whole stripe much broken up ; sides of body, 

 and limbs a lighter grey spotted with blackish ; lower surfaces 

 dirty white the belly and limbs marbled or spotted with blackish, 

 in the males the lips and throat also, the concealed surfaces of the 

 body (axillae, groin, front and hinder surface of thighs, inner surface 

 of tibiae, and upper surface of tarsus) with carmine patches and 

 spots on a black background : (b) of living specimens, the whole 

 dorsal surface is a reddish- or purplish-brown obscuring the dark 

 patch, bands and spots, disappearing more or less after immer- 

 sion in spirit ; the sides of the body greyish-blue ; the lower surface 

 pale blue marbled with blackish ; carmine spots and patches as 

 above, not much affected by spirit.
