58 Harbour Notes on some Birds from the Island of Grenada. 



Our Grenada material consists of the type already mentioned, and 

 seven others, of which three are loaned by the United States National 

 Museum; the Museum of Comparative Zoology having specimens from 

 Bequia in the Grenadine Islands, as well us St. Vincent. All the birds 

 from these southern islands of the Lesser Antillean chain are similar; and 

 have the underparts tawny, somewhat darker than Ridgway 's color on 

 plate 5. 



Planesticus nigrirostris personus subsp. nov. 



Type, from the Grand Etang, 2, 000 feet altitude, Grenada. No. 53,598, 

 Museum of Comparative Zoology, adult male. Collected by Glover M. 

 Allen, September 6, 1910. 



Characters. Similar to P. nigrirostris (Lawrence) of St. Vincent, but 

 differing in that the upper parts are much more darkly olivaceous, less 

 reddish olive; the lower parts more grayish, less rufescent ; and the under- 

 wing covers rather paler. 



Remarks. Mr. Ridgway, in Birds of North and Middle America, has 

 already called attention to these differences. The characters being con- 

 stant, as a comparison shows, these birds may be considered separate 

 subspecies, as he suggested possible. 



Among the birds credited to Grenada was one described from a single 

 young specimen in very bad preservation, the only one ever known, and 

 called Blacicus flaviventris Lawrence. 



Wells, known for so many years as a collector of Grenadian birds, tried 

 in vain to find other specimens of this extremely rare Tyrant bird. Dr. 

 Allen was especially cautioned to w T atch for it, and by rare good fortune 

 secured an adult male in the deep forest near the Grand Etang, a lake in 

 the central part of the island at an altitude of about 2,000 feet. This speci- 

 men was the only one which he saw, in spite of a long and careful search 

 It was obvious at once that the bird was very different from any other 

 Blacicus; and Mr. Ridgway, when he saw it, decided definitely that it 

 was really an Empidonax; although there was no doubt as to the identity 

 of this specimen with the remains of the type, now in the United States 

 National Museum. As the specific name flaviventris is preoccupied, it 

 becomes necessary to give this bird a new name. A note regarding its 

 relationships, and a description follow. 



Empidonax johnstonei nom. nov. 



Described from an adult male, No. 53,591, Museum of Comparative 

 Zoology; from the Grand Etang, Granada, B. AV. I., 5 Sept., 1910, col- 

 lected by Glover M. Allen. 



This Tyrant bird apparently has been derived from Empidonax law- 

 rend Allen, of Trinidad, but it has become differentiated by isolation to a 

 considerable extent. I have been enabled to make direct comparison 

 with a fine male of E. lawrencei (American Museum of Natural History 

 No. 59,067) thanks to the courtesy of Mr. Dewitt A. Miller. 



Characters. Similar to E. lawrenceibut smaller; with a narrower bill ;
