normally. Labials ^ or the seventh upper and the seventh 
lower largest, the fifth and sixth below the orbit. Three enlarged 
temporals. Ear opening oval, with two to four projecting lobules 
anteriorly, its vertical diameter almost as long as the eye opening. 
Twenty-eight smooth or feebly straited scales round the body, those 
on the verterbral line slightly enlarged, those on the sides smallest. 
Praeanals not or but feebly enlarged. Limbs moderate; when 
adpressed they just meet or slightly overlap. Toes slender, com- 
pressed ; eighteen to twenty lamellae under the fourth. Tail 
cylindrical or very slightly depressed at the base, a little longer 
than the head and body ; no series of transverse scales dorsally 
except in reproduced portions. 
Colour (Spirits) : — Dark or yellowish olive above. Head 
shields with irregular dark brown markings. Two dark brown 
bands which sometimes coalesce, start on the parietals and extend 
on to the back, where they break up into spots. Numerous trans- 
versly arranged yellow spots on the back and tail. A dark brown 
band starts on the loreal region and extends on to the side where it 
breaks up into spots. Labials yellow, sometimes barred with brown 
Throat reticulated with brown. Under surfaces uniform yellowish. 
Length of largest specimen, from snout to vent, 95 mm. 
Egernia formosa has the general appearance of E. striolata,^ 
Peters, but in reality is widely separated from that species. In Dr. 
Werner’s key ^ to the species of the genus Egernia it must be 
placed in the division I. A., the species of which are characterised 
by the cylindrical tail and the smooth scales. Of the five species 
in this division it shows affinity with the first two only, Egernia 
luctuosa, Peters* and E. lauta, de Vis.* From the former it is dis- 
tinguished by the presence of a curved groove behind the nostril 
and in having twenty-eight scales round the body ; from E. lauta it 
also differs by the possession of a post-narial groove, while there are 
no infraoculars in E. formosa and much longer limbs. 
The separation of the palatine bones by the palatal notch is 
characteristic of Egernia.® Though this condition is maintained in all 
my specimens yet the fleshy intergument covering them over-reaches 
their edges so that they appear to be in contact in the median line.
