Pentland Hills, Penang.” Stoliczka (J. A.S.B. 1873, p. 113) 
found it in the collection he got from Penang and Province 
Wellesley, and also (J. A. S. B. 1870, pp. 161, 162) mentions a 
specimen of Gecko smithii in the Fort Pit Museum said to be from 
Penang.

Platydactylus monarchus, Cantor, p. 19. 
Gecko monarchus, Boul. Cat. Liz. 1. p. 187. 
Cantor says, “In the valleys and on the hills of Penang it is 
very numerous, swarming at night in rooms, on the walls, and 
under the ceiling;” he also mentions the Malay Peninsula and 
Singapore as localities. Miiller records this species from Singapore 
in the Bale Museum. There are specimens in the British Museum 
from Penang and Singapore. I did not see this Gecko in Penang, 
but I found it common about the aviary in the Botanical Gardens, 
Singapore. 
Hab. Ceylon, Malay Peninsula and Archipelago.

Cantor mentions two specimens captured in a villa on Penang 
Hill. Stoliczka says it is not uncommon in Penang, but from 
what I heard from inhabitants it must at any rate be rarely seen.

The type specimen, a female, is from Singapore from General 
Hardwicke’s collection. I caught a male on a wooden post in the 
Experimental Gardens, Penang Hill, 1900 ft. Total length 155 mm. 
(H.B. 80, tail 75). It tried to bite fiercely when handled. Both 
specimens are now in the British Museum.

Cantor gives Malayan Peninsula and Penang as localities for 
this species. Stoliczka says it “‘ appears to be more common in 
the jungles of the Wellesley Province and near Malacca, than it 1s 
on Penang itself.” Mr. Mitchell gave me two specimens caught 
at Kulim, Kedah. In February, March, and April of this year 
I found this species very numerous about Tanglin, Singapore ;
