irides of a brownish green. Toes with very minute suckers, scarcely visible, 

 appearing as if none existed : toes five on each foot, long and nearly equal. 

 The colour of the animal is very changeable ; a dark variety with deeper 

 markings has been brought to me from Mount Harriet. The species 

 appears to be peculiar to the Andamans, where it is found under stones, 

 stumps of trees, &c. 



4. Gecko Tytleri n. s. (Tytler) ; from 4 to 6 inches long ; body and 

 tail rough, covered with small tubercles ; the tail has also spines on it. 

 Toes five ; the thumb small ; suckers on the toes small. General 

 colour brown, lighter on the under surface ; colour very changeable, 

 Irides brown. Found all my specimens in dark cellars at Moulmein, 

 where the species is common. 



5. Gecko chaus, (Tytler). I think this is Hemidactylus froenatus of 

 Schl. Length from 4 to 5 inches ; tail as long as, or longer than body. 

 General colour slate grey, lighter on the under surface ; colour very 

 changeable ; body smooth with dark marks ; tail with spines. Feet with 

 five toes ; thumb small ; suckers on toes of moderate size. Irides brown. 

 Found on trees, in houses, &c, at Moulmein and Rangoon : those found 

 at Eangoon are somewhat smaller than those from the former place, and 

 a slightly darker variety. 



6. Gecko caracal, n. s., (Tytler) ; very similar to the above, but 

 without any spines on the tail ; found in dark cellars, but chiefly in 

 native hutsjat Rangoon. Length about 4 inches. At first from its great 

 similarity to No. 5, Gecko chaus, I was inclined to think it was 

 simply a local variety of that animal, but I now feel satisfied it is not 

 so, but a distinct species. It can at once be distinguished from Gecko 

 chaus by the absence of prickles or spines on its tail, this latter 

 being perfectly smooth in Gecko caracal, 



7. Gecko pardus, (Tytler) ; length from 4 to 5 inches ; body much 

 compressed ; tail flat, thick and fleshy at base, passing off to a fine point. 

 Body dotted with light spots, margined with minute dark spots and 

 specks ; general colour brown, very changeable ; lower portions lighter, 

 without marks. Irides metallic yellow like brass. Toes five, full size, 

 connected by a membrane ; suckers full size. A great variety of markings 

 found in different individuals. Found in houses at Rangoon, Moulmein 

 and Port Blair : those obtained at Port Blair have a thicker tail than 

 those I collected in Burmah. I am of opinion that the Port Blair
