found with any certainty south of Träng. The type specimen 

 of Lyncornis temmincJdi came from Borneo. In a specimen 

 from that island in tlie collections of the R. Nat. Hist. 

 Museum of Stockholm tlie tips of tlie feathers on the breast 

 are much broader and darker than in the specimen from 

 Perak in which they are almost white and only faintly tinged 

 with chestnut. 



69. Aiitliracoceros coroiiatus convexus Temm. — 1 J 

 ^k 1915. Iris: brovvn. South of Kedali this Hornbill is fairly 

 common, but north of that State it is replaced by Antlira- 

 coceros alhirostris Shaw & Nödd. 



70. Halcyon coromaiula iieopliora Oberh. — 1 J" 7^ 

 1915. Iris: brown. Wing: 105 mm.; Tail: 65 mm.; Culmen: 

 52 mm. Of the Ruddy King-fisher several geographical races 

 have been distinguished (vide Oberholser Proc. U. S. Nat. 

 Mus. Vol. 48, 1915, pp. 639—657). In the typical form, to 

 which, according to Oberholser, the Malayan birds vvould 

 belong, the breast is only slightly washed with magenta. The 

 size is rather large, the Avings measuring more than 110 mm., 

 according to the same author. In my specimen the wing 

 only measures 105 mm. in this respect thus more resembhng 

 Halcyon coromanda 7ieophora Oberh. from Sumatra, to which 

 I also have referred it. As compared with a specimen from 

 Northern Siam (Wing: 111 mm.) the lower parts of the body 

 are rather dark and washed with magenta, which colour is 

 almost absent in the Siamese specimen which is a typical 

 Halcyon coromanda Lath. 



In the collections of the R. Nat. Hist. Museum of Stock- 

 holm there is also a single specimen from the Tawi-Taw4 

 Islands. In this specimen the whole upper parts of the body 

 as well as the lower surface and especially the breast are 

 strongly washed with magenta. In this specimen the wing 

 measures 107 mm. and it therefore must belong to the race 

 described by' Temminck and Schlegel under the name of 

 Alcedo [Halcyon) coromanda minor. 



71. Halcyon siiiyniensis fusca Bodd. — 2 J^c? ^7^ 1915;
