The members of this genus show great differences from the genus 

 Micropus, as limited in tlie present volume. The character of the 

 position of the toes is generally to be seen without difficulty in dry 

 skins, but less so in mounted and often distorted specimens. I con- 

 sider this character to be an important one, as it is not only external, 

 but extends also to the structure of the first phalanges of the median 

 toes. No doul)t this has some relation to their habits, and probably 

 to the manner in which they cling to the leaves of palm-trees or to 

 grass roofs of the Xaga houses in Cachar and Assam. It is remark- 

 able that all the species contained in my genus Taehornis are 

 " Palm-Swifts," as they are justly called, while all the species of 

 Micropus frequent rocks or stone buildings. They build tiny nests 

 agglutinated with saliva to the leaves of palms or the thatch of the 

 Naga huts ; while all species of Micropus breed in holes of rocks, 

 buildings, or occasionally trees, and make totally different nests. 

 The eggs are usually two in number, but sometimes three are 

 found.
