58 Mr. W. R. Ogilvic Grant on the 



tremely closely allied that I prefer to include the Tenasserim 

 birds under that name. 



In describing T. exsul from Kina Balu (Ibis, 1888, p. 479), 

 Dr. Sharpe compares it with T. roberti, but he of course 

 refers to Mooleyit examples in the Hume and Tweeddale 

 collections. The only difference between them is that the 

 Bornean examples have the ear-coverts devoid of a slight 

 rufescent tinge characteristic of most specimens from Tenas- 

 serim and the Malay Peninsula, but not of all, for one 

 example from Klang is in this respect similar to specimens 

 from Borneo. 



The species of Tardinulus should therefore now stand as 

 follows : —
