JEgialitis alexandrinus dealbatus Swinh. 



^(jialitis dealhalus Swinhoe, P. Z. S. London, 1S70, 

 p. 138 : south coast ot" (Hiina, including Formosa and Hainan. 



The eastern race ot' the Kentish Plover is not rare in Siam 

 during the winter months, and specimens have been recorded 

 from Koh Kram, Koh Lak, Koh Samui, and Koh I'ennan. 



^gialitis alexandrinus peroni Schleg. 



Charadrius peroni Schlegel, Mus. Pays-Bas, C^ursores 

 sp. 33, 1865 : Borneo. 



Resident in the Malay Peninsula and probably in penin- 

 sular Siam, but records very few. Specimens collected at 

 Koh Lak and on Pulu Telibun. 



JEgialitis dubia jerdoni Legge. 



^■Egialilis jerdoni Legge, P. Z. S. Lond. 1880, p. 39 : 

 Ceylon and central India. 



The specimens collected at Koon Tan in northern Siam by 

 the present autlior belong to the above-mentioned race. 

 The Little Uinged Plover is, however, quite common in 

 suitable localities during the winter-time, but as it has always 

 been recorded under the name of ^Eyialitis duhia only, 

 and being not differentiated subspecifically, it is uncertain if 

 it belongs to the race described by Legge or to the typical 

 form, ^'Egialilis duhia duhia Scop., founded on specimens 

 from Luzon in the Philippine Islamls. According to 

 Hartert and Jackson, this form '• breeds and is resident on 

 the Philippine Islands, in Hainan, Formosa, and ap[)arently 

 parts of south China, and occurs sometimes on the Japanese 

 Islands.^' The wings of A. duhia jerdoni Legge measure 

 from 103-112 and even 111 or 115 mm., while the wings of 

 A. dubia duhia Scop, measure 109-116 and even 118 mm.
