One specimen only is in the 
collection, and I am 
in consider 
able doubt as to whether I have correctly identitied the species. 
LyOOSOma ( Liolepisma) bicarinatum. 
Heteropus bicarinatus, Made ay, Proc. Linn. Soc. J\ r .S. W. ii. 
1877, p. 68. 
? Heteropus bicarinatus, Big., Catal . Liz. (Ed. 2) iii. p. 286. 
Heteropus albertisii, Peters <L Daria, Ann. Mus. Gen. xiii. 1878, 
p. 362. 
Lygosoma albertisii, Bly lac. cit. 
Coloi's — Upper surface of head uniform brown, the sides 
yellowish profusely ornamented with black spots ; back and sides 
brown with numerous darker and lighter spots ; tail light reddish- 
brown with a series of transverse black spots superiorly, and a 
few lateral spots, which are more numerous near the base ; under 
surface yellow, the tail with a reddish tinge, the chin and throat 
with a few scattered black spots ; ( L. bicarinatum.) 
Colors — Upper surface of head brown, with or without a few 
scattered black spots, the sides yellow, clouded with light brown 
or with a few spots ; back olive-brown with scattered black spots, 
and with or without two narrow faint longitudinal light bands ; 
sides with two yellow black-edged longitudinal bands, separated 
by a broader black or dark brown band, which commences at 
the nostril, and, passing through the orbit, is continuous to the 
very tip of the tail ; rest of tail as in L. bicarinatum ; under 
surface uniform yellow ; ( L. albertisi). 
Of the ten specimens now before me four belong to the latter 
form and three to the former, while the remaining three, though 
differing considerably inter se, are distinctly intermediate between 
the two described, which may therefore betaken to be the extreme 
forms of the species ; there is not the slightest difference in even 
minutest details of outward structure. 
Sir William Macleay’s types, which are now deposited in the 
Museum of the Sydney University, have been personally examined 
and compared with our recent specimens.
