t 1004. Rhynchocydus sulphurescens berlepschi Hart. & Goods. = Rhynchocydus 



sulphur, exortivus. 



Rhynchocydus sulphurescens berlepschi Hartert & Goodson, Nov. Zool. xxiv. p. 415 (1917 — " Northern 

 Venezuela (Cumana, Puerto CabeUa and Trinidad). 



Type : ^ ad., Caparo, Trinidad, 9.iv.l902. E. Andre leg. 



Hellmayr writes to me as follows : 



" A series from Santa Marta, received through Chapman, proves the birds 

 from N. Venezuela (Caribbean Coast), Trinidad, and Sta^ Marta to belong to one 

 and the same form, the oldest name of which is exortivus Bangs. The specimens 

 from Colombia in the Tring Museum formerly labelled R. s. exortivus by myself 

 are, however, R. sulph. asemus Bangs. My wrong identification evidently misled 

 you to redescribe exortivus as berlepschi." 



t 1005. Rhynchocydus megacephala flavotectus Hart. = Rhynchocydus 



cinereiceps marginatus. 

 Rhynchocydus r/iegacepliala flavotedus Hartert, Nov. Zool. ix. p. 608 (1902 — S. Javier and Paramba). 



Type : ?, S. Javier, N.W. Ecuador, 60 feet, 25.vii. 1900. G. Flemming leg. 

 No. 893. 



Chapman, Distrib. Bird-life Colombia, p. 436, suggested that flavotectus is 

 the same as marginatus Lawr. from Panama. This is quite correct. 



Hellmayr writes to me as foUows : 



" Through the kindness of F. M. Chapman I have been able to compare the 

 type of R. marginatus Lawr. with the type of flavotectus, and found them practically 

 identical. 



" I was quite wrong in referring flavotectus ( = marginatus) as a subspecies 

 to R. cinereiceps. The latter is the northern representative of the sulphurescens 

 group. R. marginatus, however, in some locahties Hves side by side with races 

 of R. sulphurescens, and is specifically different. Its nearest relations are with 

 R. poliocephalus sclateri (megacephala auct. nee Swainson !), as had been recognized 

 with his usual acumen by our late friend Berlepsch. The specimens from Guaya- 

 quil and Esmeraldas in W. Ecuador, mentioned by Chapman as being probably 

 referable to flavotectus, turned out to belong to R. sulphurescens aequatorialis 

 Berl. & Tacz. ! "
