58. Dendroica vigorsii achrustera (Bangs). New Providence Pine 

 Warbler. — This very distinct race is common on New Providence 

 Island among the open pine woods, and we found birds in song during 

 our stay there in early and late July. On July 26 an adult female was 

 watched for some time as she waited upon one of her fully grown young. 

 The latter was restless and during the intervals when its parent was 

 absent in search of food, would fly here and there among the trees keep- 

 ing up a constant chipping characteristic of many young warblers, in 

 order that its parent might find it when she arrived with food. 



59. Dendroica vigorsii abacoensis Ridgway. Abaco Pine Warbler. — 

 Several specimens were obtained at Great Bahama, July 17 and 18, 1904, 

 and these agree precisely with Ridgway's description of the Abaco bird. 

 There can be no doubt that this is the form characteristic of the large 

 islands of the northern group of the Bahamas. Since it frequents the 

 open pine woods only, its range is restricted to the islands of Great 

 Abaco, Little Abaco, and Great Bahama, where these trees grow. The 

 habits and song of both these subspecies seemed indistinguishable from 

 those of our Pine Warbler of the northern United States. 



60. Geothlypis tanneri Ridgway. Tanner's Yellowthroat. — Unfor- 

 tunately our collections do not throw very much light on the somewhat 

 complicated problem of the geographical relationships of the various 

 Bahama Yellowthroats. We were unsuccessful in finding the genus at 

 all on New Providence, and after careful search among the islands of the 

 northern group found only the species tanneri. This is common in 

 bushy growths both on the "main " islands and on several of the larger 

 cays. At Great Bahama a number of individuals were found both in the 

 swamps along shore and among the bushes in the dry pine woods. All 

 the specimens obtained are typical tanneri. The adult males still retained 

 (July 18) their black cheek-patches, though the breeding season was about 

 over. Specimens were taken on Great Bahama and Moraine Cay, and 

 birds were also observed in full song on Abaco and Elbow Cay. At 

 Moraine Cay, July 14, an adult male was seen feeding a full grown young 

 bird which followed its parent closely, begging for food. The species 

 incompta described by Ridgway from two Abaco specimens taken early in 

 April, 1886, seems to represent the group of Yellowthroats with light 

 abdomens. If it is actually resident among the northern Bahamas it is 

 odd that we did not find it. 



61. Mimus gundlachi (Cab.). Bahama Mockingbird. — On the outer 

 cays where there is an abundance of thick bushes and tangled creepers 

 this Mockingbird is not uncommon, although we found it rather shy and 

 retiring. None were seen on any of the large islands, although Mr. 

 Bonhote has found them in winter on New Providence and Little Abaco. 

 At the time of our visit they seemed to be about through breeding, 

 though some were seen tending fully grown young. Thus on Moraine 

 Cay, July 13, an adult male was seen hopping quickly about on the ground 

 among the undergrowth closely followed by two young birds whom he 

 fed from time to time. The latter kept up all the while a fine sibilant
