recently described from Denham on the Peron Peninsula, Shark 
Bay. The following short definition will distinguish the two 
species. 
D. alboguttatus, Werner. 
Snout a little longer than the distance of the eye from 
the ear opening. Ear opening obliquely elliptical. 
Rostral almost twice as broad as high, rectangular. 
Mental not longer than the adjoining labials. Nasal 
opening in contact with the rostral, one upper labial and 
four nasals, the upper (supranasals) in contact mesially. 
D. woodwardi , sp. nov. 
Snout as long as the distance between the eye and the 
ear opening. Ear very minute. Rostral twice as broad 
as high, roughly pentangular, nicked above. Mental 
slightly longer than the adjoining labials. Nasal open- 
ing not in contact with the rostral, and the supranasals 
are separate mesially by two hexagonal enlarged 
granules. 
There are also colour differences which, however, are better 
shown by a comparison of the two figures. 
Locality. — I have examined only a single young example from 
Western Australia. 
Type. — In the W.A. Museum. 
DIPLODACTYLUS LUCASI, nom. nov. 
Diplodactyius bilineatus, Lucas and Frost, Proc. Roy. Soc. Viet., Ser. 2, XV., 1903, 
p. 146 (not Diplodactyius bilineatus, Gray, Cat. Liz. Brit. Mus., 1st ed., 
1845, p. 149, and Zool. Erebus & Terror, Reptiles, pi. XV, fig. 3.) 
The name Diplodactyius bilineatus, Lucas and Frost, is antedated 
by the same name proposed by Dr. J. E. Gray for a Gecko which 
Dr. Boulenger now regards as synonymous with Phyllodactylus 
ocellatus, Gray. As it becomes necessary to propose a new name for 
Messrs. Lucas and Frost’s species, I have much pleasure in 
associating the name of Mr. A. H. S. Lucas with it. 
It is worthy of remark that Diplodactyius michaelseni, described 
and figured by Dr. Werner x , bears a general resemblance to Dr. 
Gray’s figure of Diplodactyius bilineatus, but differs materially in 
structural characters.
