 These birds yary a good deal in the amount of white on 

 their tails, one from Bandar Baroe haying practically none 

 while others haye spots on four outer pairs. On the whole, 

 however, there is less white than in Malayan and more white 

 than in West Sumatran specimens. Of the large number of 

 specimens available from all localities, those of Borneo certain- 

 ly have least, and those from the Xorthern Malayan Peninsula 

 most. Unless a new name is to be given to these birds, which 

 is undesirable, their position can be best expressed by the some- 

 what cumbrous nomenclautre used by Stresemann as Cj/mbo- 

 rhynchus macrorhynchus lemniscatus malaccensus, Salvad. 



HIRUNDINIDAE. 



113. Hirundo rustica gutturalis, Scop. 



Eobinson and Kloss. p. 154; Hartert. p. 205. 



2 8 . Deli Toewa, Deli. X. E. Sumatra, 16th October 1916 

 [Xos. 810-1]. 



$ , Toentoengan, Deli. X. E. Sumatra. 16th December 

 1917 [Xo. 858]. 



Wing, $ , 109, 112 mm. 



The specimen from Toentoengan is deeper pinky bun 5 

 "beneath with a fairly regular black collar on the fore neck. It 

 is possibly a specimen of the true H. r. rustica. Linn., on mi- 

 gration. It is, however, heavily in moult and as no exact 

 dimensions can be obtained it is impossible to be certain. 



114. Hirundo javanica javanica(Sparrm.). 



Eobinson and Kloss, p. 154: Hartert, p. 207. 

 $ 2 , Polonia. Deli. X. E. Sumatra, 1st Julv — 1st Sept. 

 1916 [Xos. 750. 812]. 



Wing, 8 , 103, 98 mm. 



We are not prepared for the present to divorce Sumatran 

 birds from the typical H. j. javanica from Java. We cannot, 

 however, separate the above specimens from birds from the 

 Malay Peninsula which Oberholser (Bull. U. S. Xat. Mas. Xo. 

 98, p. 33 (1917) regards as identical with E. domicola, Jer- 

 don, described from the Xilgiri Hills.*
