50 ANNALS OF THE QUEENSLAND MUSEUM, No. 6 
frontal half as long again as broad, considerably longer than the 
prefrontals, as long as its distance from the rostral, as broad as the 
supraocular, three-fifths as long as the parietals ; posterior nasal 
in touch with the single preocular ; postoculars two ; temporals 2+2, 
lower anterior large, wedged between fifth and sixth upper labials, 
third deeper than fourth ; six upper labials, third and fourth 
entering orbit ; chin shields equal, anterior in touch with four 
lower labials ; scale rows round the body, 19 ; ventrals, 181, rounded. 
Subcaudals, 39 single and 11 pairs ; anal divided. Upper surface 
black, most of the scales of the dorsum with a yellow large median 
spot ; lower surface lead grey, the anterior ventrals marbled with 
whitish. Length, 1070 mm ; tail, 70. One example in al. Habitat, 
Cecil Plains, Queensland. 
Denisonia nigra n.s. 
Eye large, greater than its distance from the mouth ; rostral 
considerably broader than deep, but little visible from above ; inter- 
nasals about two-thirds as long as the prefrontals ; frontals once 
and two-thirds as broad as long, once and a-half as long as its 
distance from the tip of the snout, shorter than parietals, scarcely 
broader than the suproculars ; nasal entire, in touch with the 
single preocular ; two postoculars ; temporals, 2 + 3 ; six 
upper labials, third and fourth entering orbit ; anterior chin shield 
the shorter and broader, in touch with three lower labials ; scale 
rows, 15 ; ventrals, 126 ; subcaudals, 42, in one row ; anal entire. 
Black above, a faint white line on upper edge of upper labials ; 
below, ventrals edged with white, their centres white, spotted 
with black; under side of tail, flesh colour. One young example 
in al. Habitat, Tasmania. 
Structurally, this snake approaches D. superba pretty closely ; 
but for its smaller number of ventrals and greater of posterior 
temporals, one might suspect it to be a young melanotic individual 
of that species. 
Denisonia fenestrata n.s. 
Eye small, shorter than its distance from the mouth ; rostral 
broader than deep, not or scarcely visible from above ; internasals 
less than half as long as prefrontals ; nasals semidivided, far removed 
from the single preocular ; frontal one-fifth longer than broad, 
as long as its distance from the tip of the snout, shorter than the 
parietals, two and a-half times broader than the supraoculars ; 
two postoculars ; temporals 2 + 2, the lower anterior as usual ; 
six upper labials, the third and fourth entering the orbit ; chin shields 
equal, anterior in touch with four lower labials. Scale in 17 rows 
round the body,; ventrals, 167-175 ; subcaudals, 28-42 pairs ; 
anal divided. Above dark reddish brown ; scales all with yellow 
margins ; beneath yellow, immaculate ; upper lip and temples 
reddish yellow. Two examples in al. Queensland. 
Sufficiently differentiated from its nearest ally in structure, 
D. woodfordii.
