EHAMPHOC^NUS. 219 



occurs within the limits of our country. The whole genus has a wide range in Tropical 

 America, the most southern member occurring in South-eastern Brazil. 



1. Ehamphocseuus semitorquatus. 



Rhamphocanus semitorquatus, Lawr. Ann. Lye. N. Y. vii. p. 469 ^ ; ix. p. 108 ° j Salv. P. Z. S. 1867,

Rhamphocmnus cinereiventris, Scl. & Salv. P. Z. S. 1879, p. 525 (nee Scl. ?) '. 



Supra rufescenti-murmus, pileo rufescentiore ; capitis et cervicis lateribus rufis, hoc colore infra nigro margi- 

 nato : siibtus gula alba, abdomine toto cinereo, pectore nigro striato ; cauda nigricanti-brunnea, rectricibus 

 immaculatis : rostri maxilla nigricanti, mandibula albida, pedibus obscure corylinis. Long, tota 3" 7, 

 alee 2*0, caudse rectr. med. 1*1, rectr. lat. 0*9, rostri a rictu 0'9, tarsi 0-9. (Descr. maris ex Veraguas, 

 Panama. Mus. nostr.) 

 5 man similis. 



Hab. Costa Eica, La Balsa (Carmiol^), Eio Sucio (Zeledon^), San Carlos {Boucard^) ; 

 Panama, Santiago de Veraguas ^, Calovevora ^ {ArcS), Lion Hill {M'Leannan ^ ^). — 

 Colombia^. 



This species must for the present be considered doubtfully distinct from B. cinerei- 

 ventris, a bird described and figured by Mr. Sclater in 1855 from a specimen now in 

 the Derby Museum at Liverpool, obtained by Delattre at Pasto in Colombia. At our 

 request the type has been kindly lent us for re-examination, and we can now affirm that 

 a male from Veraguas in our collection exactly agrees with it in all respects except that 

 it lacks the conspicuous brown postocular stripe that exists in the type as shown in 

 Wolf's drawing. There is just a trace of this stripe in one of our specimens, but in 

 the rest it is absent. Our impression is that this- stripe is not constant ; and if so 

 Mr. Lawrence's name will have to be placed as a synonym of B. cinereiventris, a course 

 adopted by Sclater and Salvin in 1879 ^. If, however, the receipt of more specimens 

 confirms the differences now apparent, B. semitorquatus must stand, but the bird called 

 B. cinereiventris in Mr. Sclater's Catalogue, from Sarayacu in Ecuador, having no post- 

 ocular spot whatever must be either considered distinct from both described species or 

 merged with B. semitorquatus. 



The range of this species in our country is limited to Costa Rica and the State of 

 Panama, but it appears to be everywhere rare. The first specimens procured were 

 from the line of Railway ^. A small number were afterwards sent us by our collector 

 Arce fi'om the neighbourhood of Santiago de Veraguas ^, and it has also been found by 

 several of the collectors of Costa Rica ^ ^ ^.
