THE ISLANDS OF THE BAY OF BENGAL, 237 



590.— Motacilla luzoniensis, Scop. (0.) 



Colonel Tytler and Captain Beavan say that this species is 

 common at the Andamans in the cold season. None of us 

 ever procured a specimen or indeed saw one (save a single bird 

 seen by Dr. Stoliczka in Macpherson's Straits), neither did Davi- 

 son, and considering how long he remained at the islands, and 

 how entirely he devoted himself to collecting, we may safely 

 assert that it is not now-a-days at all common in the cold 

 season. I cannot say that I have the least confidence that 

 Colonel Tytler correctly identified the particular species of 

 grey wagtail that he saw, and Dr. Stoliczka could not, of 

 course, be certain, but we may accept the fact that some grey 

 wagtail does occur at the Andamans, and hence I admit the 

 above species into our list partly to indicate this, and partly 

 because of this group luzoniensis is the species most likely to 

 occur. 



592.— Calobates boarula, Perm. (6.) 



The Andaman specimens belong to the somewhat smaller 

 race which alone, so far as I am yet aware, occurs within our 

 limits, and which Pallas separated as melanope. So far as I 

 can discover the only difference between the two races is in 

 size, the European being somewhat the larger of the two. I 

 must confess that I scarcely think this difference sufficient to 

 warrant specific separation. 



We ourselves only met with a single specimen on Preparis, 

 and one or two elsewhere, and Davisen remarks "not common 

 on the Andamans or Nicobars, at the former place I did not 

 observe more than half a dozen, and only one at the Nicobars." 



I do not suppose that this bird is a permanent resident, but 

 four specimens have been recently sent me killed from the 

 4th to the 9th September, and we killed a specimen on Preparis 

 as late as the 26th March, so that at most they are not absent 

 for above five months from the islands. 



593 ter— Budytes cinereocapilla, Savi. (2.) 



This is the Long-hind-clawed Yellow Wagtail, with the dark 

 slatey grey head, and no conspicuous white supercilium. This 

 occurs both at the Andamaus and Nicobars. 



Davison says: — "1 secured only two specimens of this wag- 

 tail shot at Camorta, Nicobars, and Aberdeen, South Andaman, 

 but I have no doubt that I overlooked it among the large flocks 

 of B. flava that occur both on the Nicobars and Andamans.
