 545. fig. 2. — Cayenne]. 



One ? ad. from Seelet, Ajiril. " Iris brown.'' Not different in any way from 

 Brit. Guiana and Pari'i examples. An adnlt male has been collected by Mr. Andre, 

 near Castare, Tobago, May lu, 19U3. It also agrees with mainland specimens. 



23. Stelgidopteryx ruficollis aequalis Bangs. 



IHiriiiidn rtificollis Vieillot, Nam: Did. xiv. (1817) p. 523 (ex Azara No. 30(j. — Paraguay)]. 

 Stelqiddpteryx rufirnllis ueqiiaVm Ontram Bangs, Pioc. Ni')o Engl. Zaol. CI. ii. (1901) p. 58 [type 

 from Santa Marta]. 



1 rj ad. Laventille, May ; 1 ? Chaguaramas, Jannary : 1 <? ( 'aroni, April ; 

 and 1 S from Cangrejal, May. 



These specimens have the rump ashy whitish, in marked contrast to the dark 

 brown back, agreeing in that respect with a good series from Cnmana, Garthagena, 

 British Guiana, Merida, and the Orinoco and ('aura Rivers. Tin's form, which has 

 been well described by l\Ir. Bangs, differs from S. r. aropyf/ialiii (Lawr.) in its 

 decidedly paler rufous throat anil paler brownish grey chest and sides. S. r. nijicollis 

 (Vieill.) is easily recognisable from both by having the whole upper surface 

 UMJfornily dark brown without any trace of the ashy whitish rnnip band. 



I have but a few words about the geograiihical distribution to add to Mr. Bangs' 

 excellent account. 



1. .S'. n/ficoliis 1-nfcolh's (Vieill.). 



Distribntion.— Paraguay ; Brazil : Uio, S. Paulo, Minas Geraes, Bahia, 

 Mattogrosso, Gnyaba, Gaicara (Natterer coll.), west to the eastern 

 slopes of the Andes in Peru and Ecuador ; and east to Para on the 

 month of the Amazons. 



Obs. I have before me 2 adult SS from Nauta (N.E. Pern) and 2 cJc? 

 and 1 ? from Archidona, East Ecuador, which agree perfectly 

 with specimens from Eastern Brazil, and show no approach to the 

 pale-rumped form found on the western side of the Ecuadorian Andes. 

 Three examples from Parii are also qnite identical. 



2. S. ruficollis uropjujiuUs (Ijawr.). 



Distribution. — Gosta Bica ; Ghiriqui, Panama ; and soutli wards thrnugh 

 Western Golombia (Remedios, etc.) to AVestern Ecuador. 



Obs. A good series from West Ecuador and 1 i jr. from Remedios, 

 Antio(|uia, agree with others from Gosta Rica, etc., and avi' mui'lt 

 darker everywhere than .S'. /■. iicipud'n. 



3. S. nificollis ueqnalis 0. Bangs. 



Distribution. — North coast of (lolombia (Garthagona, Santa JIarta) : 

 Bogota coll. ; Venezuela : Jlerida, Cumand, Orinnco and ( 'aura Rivers ;
