10 EINAR LÖNNBERG AND L. G. ANDERSSON, DR. E. MJÖBERGS EXPEDITIONS TO AUSTRALIA. 3. REPTILES. 
Lygosoma maccoyi Lucas & Frost. — One specimen from the neighbourhood 
of Melbourne, June 1911, agrees with the original description, except that there are 
9 smooth lamell&e under the fourth toe, instead of »six or seven» as the authors 
quoted have stated. In this respect this species approaches Lygosoma gracile BAVAY. 
from New Caledonia which has 11 or 12 such plates according to BoULENGER (Cat. 
Liz. B. M. III, p. 332). Considering the great resemblance between L. maccoyi and 
L. gracile it may be sad that the former substitutes the latter in Australia. L. 
gracile which still possesses prefrontals, although they are small, represents, the 
more primitive stage, and L. maccoyi might be regarded as a L. gracile in which the 
small prefrontals are coalesced with the frontonasal. The form of the suture be- 
tween the frontonasal and the frontal in L. maccoyi proves this. 
Another specimen from Blackal Range, southern Queensland, '”/, 1911, has eight 
lamell&e under de the fourth toe, and is thus intermediate between the typical one 
and the variety just mentioned. 
The authors quoted above have described this species from several different 
localities in Victoria. 
Lygosoma graciloides n. sp. — Three specimens from Yandina at the foot of 
Blackal Range, Southern Queensland, "/, 1911. 
Body small and slender, limbs weak, not meeting; the distance between the 
end of the snout and the fore limb contained about once and a half in the distance 
between axilla and groin. Snout short, moderately pointed. Lower eyelid with an 
undivided transparent disk. Nostril pierced in the nasal; no supranasals; rostral 
broad and joined with the very large frontonasal with a very broad suture; no 
prefrontals, and consequently the suture between the frontonasal and frontal is long 
and curved; frontal shorter than frontoparietals and interparietal together, in contact 
with first and second supraoculars; four supraoculars, third largest; 7—8 supraciliaries; 
frontoparietals and interparietal distinct, the latter smaller than the former; parietals 
forming a rather long suture behind the interparietal, and bordered by a pair of 
nuchals and a pair of temporals; a second pair of enlarged nuchals behind the first, 
the following scales passing gradually into the dorsals. Fourth upper labial below the 
centre of the eye. HEar-opening small. 20 smooth scales round the body; the two 
dorsal series largest. Preanals a little enlarged. Four digits and five toes; about 
twelve subdigital lamellxe under the fourth toe. 
General colour uniform? (coppery) brown above, whitish below. There is no 
sharp line of demarcation between the colours on the sides of the body, but a dusky 
line along the sides of the tail is in some of the specimens continued forward over 
the flanks. 
Distance from snout to vent 26 mm., tail 27 mm. in one specimen. The two 
others have had their tails mutilated and regenerated, but head and body measure 
resp. 25 and 29 mm. 
1 Under the magnifying-glass three to five dark streaks are to be seen on each scale.
