A NEW GENUS OF ENGYSTOMATID.E — FRY. 93 



of the hind limb stretched out, from the anus to the tibiotarsal 

 articulation, equals the distance between the anus and the loreal 

 region. Skin smooth. 



Colour (spirits). — Brownish above with darker brown spots. 

 Sometimes a light silvery band commencing behind the eye-lids, 

 narrowing and continuing to the anus as a broad dorsal stripe. 

 Upper surface of head light silvery grey. Loreal region dark 

 brown. A more or less broken band of dark brown commences 

 behind the eye and continues to the axilla. In the scapular 

 region, are two brown, light-edged spots, more or less resembling 

 ocelli ; a similar marking on each side of the urostyle. Sides and 

 under surfaces light brown, irregularly speckled with lighter 

 brown and yellow. 



Total length, from snout to vent, 2 I mm. 



This species differs from the preceding chiefly in the smaller 

 tympanum, much larger finger discs, very small first finger, and 

 distinctive colouration. 



Locs. — One specimen from Russell River, North-east Queens-

Habit slender. Head almost as long as broad. Snout rounded,

 than the orbital diameter. Nostril slightly nearer the tip of the 

 snout than the eye. Can thus rostralis rounded ; loreal region 

 oblique, concave. Interorbital space much broader than the 

 upper eye-lid. Tympanum hidden. Lower jaw distinctly truncate. 

 Tongue elongate (injured 3 ). Palatine ridges not distinguishable. 

 Palate very flat ; choanse distinct. Anterior palatal ridge hardly
