332 DR. J. ANDERSON ON THE MAMMALS, REPTILES, AND 



Among the five species of bats represented in the collection, 

 Emballonura semicaudata is new to the Malayan Peninsula ; while 

 another, Ft er opus edulis, is also an addition to the fauna of the 

 Mergui district. A large bat, probably this species, occurs like- 

 wise on the islands in the neighbourhood of Sullivan or Lampi 

 Island to the south. 



A race of Sus scrofa is the mammal most generally distri- 

 buted over the Archipelago. It is found on all the large islands, 

 and on islands not over a square mile iu extent. It is known 

 to occur as far west as the Elphinstone group to the north, and 

 Clara Island to the south, these two localities, with King Island 

 and Mergui, being the northern and southern limits of my obser- 

 vations. Whether this animal extends to the most westerly 

 chain of islands, stretching from Tenasserim island in the north 

 to Great Western Torres in the south, has not been ascertained, 

 as these islands have not been explored. 



Tragulus KancJiil is another feature of the Archipelago, and is 

 almost as widely distributed as the pig. On Elphinstone Island 

 it was nearly as numerous as on King Island and at Mergui, 

 where the undergrowth of the forest is alive with it at sundown. 



After these two species, the squirrels, Sciurits caniceps and 

 S. bicolor, are the mammals most commonly seen. 



Arctofjale leucotis occurs on King, Owen, and Sullivan Islands, 

 thus rendering it probable that it has a wide distribution over 

 the Archipelago. Paradoxurus licrmaphroditus, on the other 

 hand, was only observed on King Islaud. 



The two monkeys found on the islands arc Scmnopithecus obscu- 

 rus and Macaeus cynomolgus ; the former being the more widely 

 distributed, while the latter seems to be more confined to the 

 islands near the mainland, where mud-banks are exposed at low 

 water, the food of this monkey consisting largely of Crustacea 

 found in BUch situations. 



Tupaia ferruyinea is very abundant in the neighbourhood of 

 the few villages on the banks of a creek at the head of the bay, 

 on the north-eastern side of King Island. It was also met with 

 on ;i recent clearing made by some SelungH in the centre of the 

 island, and again on Elphinstone and Sullivan Islands. 



The only Locality in which I observed the nocturnal Nyciicebus 

 tardigfadus was K i i >^ [sland, an island intimately linked to the 

 mainland by a succession of islets separated from each other by 

 narrow channels.
