BIRDS FROM SIAM AND THE MALAY PENINSULA 179 



mens the ear coverts are greenish blue. If Sauroyatis chloris humii 

 Sharpe is to be recognized, it will have to be for a form inhabiting 

 the Malay States and probably farther south. 



The range of S. c. armstrongi is from the southeastern coast of 

 Bengal to Burma, the coast of Siam, southern Indo-China, and 

 Peninsular Siam as far as Pujo Langkawi. It is a seacoast form and 

 apparently is found all along the Siamese seacoast and on the islands 

 off the coast. 



Herbert * reports it common in the nesting season at Bangkok, 

 which extends from March 10 to August. 



CARIDAGRUS CONCRETUS CONCRETUS (Temminck)

One male, Huey Yang, Kao Luang, October 6, 1930; one female, 

 Kao Chong, Trang, September 6, 1933; one female, Kao Soi Dao, 

 Trang, December 20, 1933. Dr. Smith gives the soft parts of the 

 male as follows: Iris dark brown; bill blackish brown, below yellow; 

 legs greenish yellow; the female is sim^ilar. 



Dr. W. L. Abbott collected a female at the Endau River, east 

 coast of Johore, June 27, 1901, and a female at the Rumpin River, 

 Pahang, July 5, 1902. Dr. Abbott's description of the soft parts of 

 the female is practically the same as that of Dr. Smith except the legs 

 are given as brownish yellow or yellow. 



The two females taken by Dr. Abbott were caught in rat traps in 

 deep forest far from water. 



Beside the above, the United States National Museum contains 

 only two males and one female from Sumatra with definite localities. 

 From the two Sumatra males, the single male from Kao Luang differs 

 in being much larger and in having the coverts of the wing edged with 

 lighter blue. The single male from Kao Luang measures: Wing, 

 116; culmen, 48 mm. The two Sumatra males: Wing, 104-107; 

 culmen, 44.5-45 mm. Wliether these differences would hold in a 

 larger series is problematical. 



Robinson and Kloss ^ state that Bornean specimens are darker 

 blue. 



This species seems to be rare in museums, probably on account of 

 its habits. 



It ranges from the extreme south of Tenasserim to Singapore, 

 Sumatra, Banka, and Billiton. The Bornean form has been named 

 Halcyon concreta borneana by Chasen and Kloss. ^
