14 L. G. ANDERSSON, DR. E. MJÖBERGS EXPEDITIONS TO AUSTRALIA 1910—1913. 9. BATRACHIANS. 
obtusely pointed, first shorter than second, two very distinet metacarpal tubercles 
and projecting subarticular pads. Toes short, obtusely pointed, with a slight rudiment 
of web at the base, not fringed, but provided with a very narrow ridge along the sides. 
Two large metatarsal tubercles, broad and blunt, not compressed; no tarsal tubercle. 
If the length of the tibia is marked off from the knee forwards along the body, it 
reaches the anterior part of the axilla, and if the hind limb is stretched forwards, 
the tip of the fourth toe reaches the tip of the snout. Back warty; the hind part of 
the belly indistinctly, the under surface of the thighs distinctly, granulate. Three 
large porous and rugose glands on the sides of the body, viz. a large anterior one 
from the eye to behind the shoulder, another somewhat still larger immediately behind 
the first, extending to the groin, and a small one on each side of the coccyx. No 
glands on the thighs. The upper side of the vent is distended as a vault, the free 
margin of which is deeply serrated forming a dermal fringe above the vent. 
Upper surfaces dark brownish with rather indistinet black markings, viz. an 
angular band between the eyes, two longitudinal bands on the back at the inner 
margins of the glands, and irregular spots on the hind part of the back; a large 
yellowish white spot in the groin, a small white spot at the angle of the mouth 
and a few very small light dots on the glands; brownish grey below, lighter below 
than above.

The most important differences between Ps. mjöbergii and this specimen is, that 
the latter lacks a tarsal tubercle, and has shorter hind limbs (in Ps. mjöbergii the 
tip of the fourth toe reaches a good deel beyond the snout). Besides, the colour 
is much darker, the upper surfaces more warty, and the arrangement of the large 
swellings more regular; in addition to this the habitat is quite different. Even Ps. 
mjöbergii has, however, more or less distinetly the peculiar structure of the vent, 
described above (in one of the two type-specimens the upper margin of the vent is 
entire, but in the other it is serrated, although not at all so distincetly as in the 
specimen now in question. In the main the colour-pattern and the external appear- 
ence are rather similar as well, and I believe, that it is very possible, that a further
