iS DS: 
With the exception of a short list of birds collected on the 
“Lingga Islands,’ presumably Lingga itself, by the late Alfred 
Everetts’ collectors by Dr. Hartert (Nov. Zool. vii, pp. 549-50 
(1900) I am not aware of any account of the avifauna of any 
of the Rhio-Lingga Archipelago. 
From an ornithologist’s point of view most of the small 
Indo-Malayan islands lying within the 20 fathom line from 
larger land-masses are extremely uninteresting and Mapor, 
where, with the exception of two species of sun-birds, birds 
were very scarce both fm species and individuals, proved no 
exception to this rule. A list of the specimens observed or 
obtained is however given, those of which no specimens 
were preserved being marked with an asterisk. 
1. TRERON NIPALENSIS, Hodgs. 
1d 
2. OSMOTRERON VERNANS (Linn.) 
1¢, 1%. Very common. 
*3. MYRISTICIVORA BICOLOR (Scop.). 
Extremely abundant, roosting on the small islets 
off the coast. 
4. STERNA BERGII PELECANOIDES (King). 
Thalasseus bergil pelecanoides, Oberholser, Proc. 
U.S. Nat. Mus. 49, p. 523 (1915). 
Common off the sand spits and reefs on the western 
side of the island. Two specimens, male and female, with the 
exposed culmen 61.5 and 64 mm. appear to belong to this race. 
5. AECIALITIS ALEXANDRINA (Linn.) 
Antea, vol. V, p. 142. A single male of the tropical 
race of the Kentish Plover in breeding plumage. 
*6. NUMENIUS ARQUATA (Linn.) 
*7, NUMENIUS PHAEOPUS (Linn.) 
Both the Curlew and Whimbrel were fairly common 
round Mapor but were exceedingly wild and almost impos- 
sible to approach within gunshot. 
8. LIMONITES RUFICOLLIS (Pall). 
A single female shot on June 6th. 
*g. ARDEA SUMATRANA, Raffles. 
*10. DEMIEGRETTA SACRA (Gm.). 
Common on the reefs. 
*11. HALIAETUS LEUCOGASTER (Gm.). 
*12. HALIASTUR INTER MEDIUS (Gurney). 
Common as everywhere else on the Malayan coasts.
