6. Lygosoma LEsuEURII, B. M. Cat. vol. iil. p. 225. 
Hinula australis Gray, Cat. p. 77. 
Tiliqua australis Gray, Ann. Nat. Hist. ii. 1838, p. 291. 
This species is fairly abundant on all the larger islands, 
frequenting generally the limestone slopes of the hills, and during 
the heat of the day running about with great activity. Distributed 
over Western Australia. 
7. Lygosoma 1soLepts, B. M. Cat. vol. iii. p. 234, pl. xv. fig. 1. 
Hinula tenuis Gray, Cat. p. 76. 
Rather common on the Spinifex-plains of Hermite. Diurnal, 
feeding upon flies and the smaller Orthoptera. Distributed over 
Western Australia. 
8. VaRANus GouLpit, B. M. Cat. vol. 1. p. 320. 
Monitor gouldi Gray, Cat. p. 12. 
This large species, which occurs over Northern and Western 
Australia and New Guinea, is abundant over the whole Monte Bello 
Group, wherever there are flat sandy plains of sufficient extent. 
In places the ground is riddled with its fattened burrows, which 
usually descend to a depth of two feet or so, and ascend again to 
a second entrance, though they often branch and intersect. The 
reptile is only in evidence on very hot days, and is generally 
shy and wary, running with great rapidity. It feeds upon the 
larger Orthoptera, possibly also upon small birds. On _ the 
mainland in this vicinity it is known by the name of ‘ Bung- 
arra,’ derived from the aborigines, amongst whom it forms a 
source of food. It is supposed to do considerable damage to 
young chickens and eggs in settled localities. 
9. VARANUS ACANTHURUS, B. M. Cat. vol. ii. p. 324. 
Odatria ocellata Gray, Cat. p. 8. 
This reptile is apparently scarce, for only one specimen was 
seen, being obtained on a Spinifex-plain of Hermite. On the 
mainland it is found over the north and west of the continent. 
10. TyPHLops AMMoDyTES, sp. n. (PI. I. figs. 8-10.) 
Snout rounded and strongly projecting; nostril lateral. Rostral 
narrow, the upper portion nearly one-third the width of the head, 
not extending quite to the level of the eyes. Nostril between two 
nasals, the inferior of which comes just in contact with the lower 
portion of the preocular. Upper nasal nearly as broad as the 
rostral. Frontal small, prefrontal and parietals larger than 
the scales of the body. Eyes distinct. Four upper labials. 
20 scales around the middle of the body. Tail slightly longer 
than broad, conical, ending in a short spine. Colour a uniform 
pale greyish brown, somewhat lighter on the under surface. 
Length 230mm. Diameter of body, 4mm. 
Found in the sand, under a loose rock, Hermite Island.
