Remarks. — So completely do the specimens of Caprimulgus macru- 

 rus from the island of Singapore combine the small size of the dark 

 typical form from Java, with the pale coloration of the large Capri- 

 mulgus macrurus himaculatus from the Malay Peninsula, that they 

 seem worthy a name of their own. All the specimens we have 

 examined from Sumatra belong to this race. It does not, however, 

 extend farther northward, for birds from the neighboring mainland 

 of the Malay Peninsula are Caprimulgus macrurus himaculatus. It 

 seems a little remarkable that the birds of this species from the island 

 of Singapore, so near the Malay Peninsula mainland, should differ 

 so much and resemble rather those of the distant island of Sumatra; 

 but this bears out what we have noticed in other groups of birds, and 

 indicates that the island of Singapore is, in some ornithological 

 respects at least, f aunally more closely allied to Sumatra and Borneo 

 than to the Malay Peninsula.
