habitat before any bouses on the Andamans were constructed. I 

 did not find tbe species to be common about Port Blair.

Tbe former is tbe most common house Gecko all over tbe island 

 of Penang, along tbe sea coast as well as on tbe top of tbe Penang 

 hill, at an elevation of 2,500 feet. 



The young lizard is brown, with numerous rather large round pale 

 spots all over the body, and each labial has a pale spot. Full grown 

 specimens are pale ashy, sometimes almost white, all over densely 

 and very minutely punctated with brown ; some indistinct round pale 

 spots are usually traceable on the posterior part of the head and 

 about the shoulders ; there are as a rule no brown spots on the 

 labials, which are minutely punctated like the rest of the body,, 

 though the ground colour is paler. 



In one specimen, captured on the Penang hill, the tail became 

 injured. It grew afterwards particularly thick, short, with a sepa- 

 rate short appendage above and another below on the side, no 

 enlarged shields were formed below, in which character this speci- 

 men would agree with P, Cantoris, but it has the two pairs of 

 enlarged chin shields followed by a few smaller shields on either side, 

 peculiar to P. Peronii. 



The former species, characterized by Giinther, I never 

 met with on Penang, it must be extremely rare. But it is 

 found at the Andamans, as noted by Theobald (Cat. Kept. 

 Asiat. Soc. Mus. p. 30), though also very rarely. Col. T y 1 1 e r 

 named it (characteristic of his particular desire of renaming 

 species) Gecko Harrieti, (Journ. Asiat. Soc, Bengal, xxxiii, p. 

 548). A specimen presented by Col. T y 1 1 e r to tbe Museum 

 is 2*8 inches long, it has thirteen upper, and ten lower labials, but 

 the last shields of both are very small ; central scales in forty-two 

 series; the tail is depressed, and with minute spines on the edges of 

 the front half. The general colour above is a sort of fawn colour 

 with reddish brown and yellowish undulating transverse bands, 

 between the shoulders, loins and on the tail interrupted by irre- 

 gular blackish brown spots ; a brown band extends from the rostral 

 through the eye to the shoulder, and is edged above with yellowish.
