MAMMAL SURVEY OF INDIA, BURMA AND CEYLON. 697 



secondary growth jungle, and is shut in by hills which rise to up- 

 wards of 1,000 feet, 



Thaget. — The Tenasserim Hevea Rubber Estate, on the Tenas- 

 serini River, about 60 miles above Mergui. It is accessible by 

 launch at all seasons. The area of the Estate is 5,000 acres, of which 

 about 800 acres have been cleared and planted. The average rain- 

 fall, 100-110 inches, is strikingly less than that near the coast, or 

 even as far inland as Tenasserim village, where it often exceeds 

 200 inches. 



Tacjoot. — About 75 miles up the Tenasserim River, a tin mining 

 district, it is surrounded chiefly by bamboo jungle. 



Banlaiv. — About 55 miles up the great Tenasserim River, A 

 small village on the North bank, surrounded by fruit orchards. 

 Flat country, paddy fields, and scrub jungle." 



In all 1,024 specimens were obtanied, of which 4 are missing or 

 have not been sent to me. Twenty-eight others are from places out- 

 side the area dealt with in this Report, these will be found listed in 

 a supplement. The remaining 1,000 specimens belong to 64 species, 

 in 52 genera. 



A feature of this collection which causes surprise is the almost 

 complete absence of the really small mammals (exclusive of the 

 Bats). One Pigmy Shrew and the specimens of Ghiropodomys are 

 the only ones which can be placed in this category, even the ubi- 

 quitous Mus hooclucja is unrepresented. The constant flooding of 

 such large areas, as repor-ted by Mr. Shortridge, is possibly to a 

 certain extent responsible for this fact. Chiroijodomys is an arboreal 

 animal, which would be less inconvenienced by floods than Mus, 

 Leggadilla, &c., but it is probable that large areas of heavy conti- 

 nuous forest is unsuited to the welfare of the smaller types of 

 mammals. 



Of the 64 species recorded, more than 40 or 2/3 of the whole are 

 new to our Survey Lists, three are quite new and have been des- 

 cribed by Mr, Thomas on an earlier page of this Journal, (Vol, xxiii, 

 pp. 205, 413, 612). 



Of the species recorded in this Report, all the true Monkeys ; the 

 Bat, Emballonura monticola • Gymnura and Galeopterus among the 

 Insectivores ; Arctictis and Hemigalus among the Carnivores ; and the 

 Rodents, Upimys vociferans, I], validus, Ounomys varius, and the 

 bush tailed porcupine {A. macrourus) are at or very close to their 

 Northern limit. 



Mr. Shortridge records the following notes on animals which he 

 failed to meet with though they have been recorded from this region. 



" Pithecus arctoides. — I could get no information of any kind of 

 a stump-tailed Monkey in the District. 



Pteropits. — Said to be plentiful, especially at Mergui, at certain 

 times of the year.
