Cherrie on Trinidad Birds. ^ — As the result of a month's collecting, in 

 March, 1907, in which time 300 specimens, representing 96 species, were 

 collected by him, Mr. Cherrie records five species as new to the list of 

 Trinidad birds. One of these species, Chcetura cinereicauda, is erroneously 

 given, having been pre\'iously collected and recorded by Mr. F. M. Chap- 

 man. Furthennore, the specimens on which the latter record is based, 

 and with which Mr. Cherrie's bird will doubtless be found to agree, prove 

 to be not the true cinereicauda but a new species which Dr. Hellmayr has 

 recently described as Chcetura chapynani. 



Of the remaining four species, two had previously been taken on the 

 small island of Monos, only a few hundred yards from Trinidad and, as 

 Mr. Cherrie remarks, so close to the larger island that birds of the weakest 

 flight might readily pass back and forth. 



Catharus melpomene costaricensis and Leptopogon superciliaris , represent 

 genera as well as species entirely new to Trinidad, and have never been 

 taken on the neighboring small islands. 



The Trinidad Megarhynchus which Mr. Cherrie recently proposed to 

 call M. pitangua parvirostris is now considered doubtfully separable, on 

 account of the variation in size of bill found among the continental birds. 



This list is annotated mth remarks on abundance, and exact localities 

 and dates of many specimens are given. The colors of the changeable 

 parts of many species are recorded, and there are also interesting notes on 

 habits, song and nesting. — W. DeW. M. 



^ Bangs 'On Certain Costa Rican Birds.'-— In this paper, based mainly 

 on collections made by C. F. Underwood, the following seven new forms 

 are described : Trogon underwoodi, Pachyrhamphus versicolor costaricensis, 

 Myiobius xanthopygus aureatus, Troglodytes ochracea ligea, Myioborus 

 aurantiacus acceptus, Phiogothraupis sanguinolenta aprica and Emheri- 

 zoides sphenura lucaris. 



Mr. Bangs remarks that the characters of several of these fonns have 

 already been pomted out by Ridgway in his ' Birds of North and I\Iiddle 

 America,' and more ample material has con\'inc«d the describer of the 

 desirability of providing them with names. 



Additional specimens of Chlorospingus zeledoni and Thryorchilus ridg- 

 wayi confirm the standing of these local species. Cassin's name bryanti 

 is taken up for the Costa Rican subspecies of Spinus xanthogaster, which 

 of late years has not been recognized as distinct, and a hummingbird, 

 Lophornis delattrii, is recorded for the first time from Costa Rica. 



Mr. Bangs' material also enables him to clear up the confusion that has 

 existed concerning the Costa Rican swafts. In addition to C. gaumeri and
