ENICURUS IMMACULATUS Hodgson 



Bnicurus immaculatus Hodgson, Asiat. Res., vol. 19, p. 190, 1836 (Nepal).. 



One female, Khonka Valley, January 9, 1933. 



This seems to be a new record for Siam. Its range is Garhwal to^ 

 Assam, the Chin Hills, Burma, Tenasserim, and northern Siam. 



This species is of about the same size as schistaceus and much of 

 the same color pattern, except the back is black instead of gray and 

 the white frontal patch is larger and extends farther back. 



ENICURUS LESCHENAULTI INDICUS Hartert 



Enicurus leschenauUi indicus Hartert, Die Vogel der palaarktischen Fauna, vol. 1, 

 Heft 6, p. 760, 1910 (Margherita, upper Assam). 



One male, Doi Nangka, November 13, 1930; one female, Pang 

 Meton (Doi Nangka), April 29, 1931 ; one male, Khun Tan, 3,000 feet, 

 February 20, 1932. 



Count Gyldenstolpe ^"^ says that this form is recorded from northern 

 and northwestern Siam, where specimens have been taken at Khun 

 Tan and Doi Par Sakeng. Deignan records it as uncommon on Doi 

 Sutep from 2,500 to 4,600 feet;^* de Schauensee records it from 

 Chiengsen *" and Chiengdao, 2,000 feet." Chasen and Kloss '^ list 

 it from the Raheng district, western Siam. 



The form ranges from Sikldm to eastern Assam, Burma, south to 

 Tenasserim and northern Siam, east to Laos, Tonkin, and northern 

 Annam. 



In southern China and the Shan States of Burma E. I. sinensis 

 occurs. It differs from indicus m having the second outer tail feather 

 more than 25 mm longer than the outer; in indicus there is little 

 difference in length, the outer tail feather being only about 10 mm 

 shorter. The two forms may possibly be separate species. E. I. 

 leschenauUi is found in Java, and in the only specimen examined by 

 me the outer tail feather is only about a fourth as long as the second. 

 If this condition is not abnormal, I do not believe the northern forms 

 belong in the same form group at all. 



HYDROCICHLA FRONTALIS (BIyth) 



Enicurus frontalis Bltth, Journ. Asiat. Soc. Bengal, vol. 16, p. 156, 1847 (Malay- 

 Peninsula). 



One male, Sichol, Bandon, August 29, 1929. 



Dr. W. L. Abbott took an adult female at Tanjong Badak, Tenas- 

 serim, January 5, 1900. This specimen has a brownish tinge not 

 seen in the Sichol male.
