IgIQ.| H. C. Roprinson: Notes on the Vertebrate 327 
Fauna of the Pahang-Johore Archipelago. 
10. Demiegretta sacra (Gm.) 
Extremely common. 
ll. Fregata ariel (Gould.) 
Fairly common; one was obtained in June 1908. 
12. Haliaetus leucogaster (Gm.) 
13. Haliastur indus intermedius, Gurney. 
Both very common though specimens from this locality 
have not been preserved. 
14. Haleyon chloris (Bodd.) 
Two adult males were shot on Pulau Tinggi on 18th and 
20th June rg15. Wing, 107, 105, exposed culmen, 48, 46 mm. 
I am unable to agree with Mr. Oberholser in the con- 
clusions arrived at in his recent ‘‘ Revision of the subspecies 
of the White-Collared Kingfisher,” Sauropatis chloris (Bod- 
daert). (Proc. U. S. Nat. Mus. vol. 55, 1919, pp. 35I— 395). 
I consider that the whole of the Indo-Malayan forms 
eastwards to the Philippines should be regarded as one 
species and that division into subspecies is impracticable and 
not justified by the facts. 
Our series of the form listed by Mr. Oberholser under the 
name Sauropatis chloris arvmstrong1, vastly exceeds that in the 
United States National Museum and amongst them are to be 
found all the colour variations assigned to that race, to 
S. c. cyanescens, and to S.c. palmert, from Java. 
As regards dimensions it would appear from the quoted 
measurements that S.c. cyanescens is a slightly larger form 
than S.c. aymstyongi but on the other hand seven birds 
from near Deli, N. E. Sumatra, measure g6--102 in 
wing and on this account would have to be assigned to 
the latter form, thus doing violence to Dr. Oberholser’s 
geographical distribution. Birds from West Sumatra run up 
to 113 mm. while we have specimens from the mainland 
of the Malay Peninsula and from Langkawi which measure 
10g and III mm. 
To anyone familiar with the bird, in life, it is incredible 
that the communities living on opposite sides of narrow 
straits should possess any real subspecific distinctness and 
I cannot therefore admit that birds from N. E. Sumatra are 
distinct from those from the N. W. Malay Peninsula or that 
the opposite sides of the Sunda Straits are inhabited by 
two different forms, S. c. cyanescens and S c. palmeri, 
Oberholser. 
15. Hemiprocne longipennis harterti, Stresemann.
