The late Dr. Taczanowski states that he received from Mr. Janskowski five specimens of 

 this Martin from the Sidemi Biver, in the vicinity of Wladiowstock, near the frontier 

 between the Southern Ussuri country and China. As he mentioned that the measure- 

 ments were larger than those given by David and Oustalet, and spoke of a pectoral band, 

 which is exactly the character which distinguishes C. rijjaria from C. sinensis, it seemed 

 probable that his specimens were after all nothing but the former species ; and this 

 has since proved to be the case from an examination of the specimens in question, which 

 were kindly submitted to us by Dr. Stolzmann. 



The range of C. sinensis must also be extended to the Philippine Islands, a specimen 

 being in the Cuming collection in the British Museum. 



The following additional' notes on the nesting of the species occur in Mr. Oates's 

 edition of Mr. Hume's ' Nests and Eggs of Indian Birds' : — 



" Major C. T. Bingham writes : — ' At Allahabad and at Delhi I have found nests of 

 this little Sand-Martin in eight months out of the twelve, viz. in January, February, 

 March, April, and May (one nest at Allahabad on the 3rd May, containing two very 

 hard-set eggs and two young birds), and again in October, November, and December. 

 They lay in holes excavated by themselves in the sandy banks of rivers and nullahs, these 

 being from 1 to 3 feet deep and 2 inches in diameter, ending in a nest-chamber slightly 

 larger than the tunnel, lined with straw or grass-roots, with a layer of soft feathers, on 

 which the eggs, ordinarily four or five in number, lie.'
