Characters of Eight New Species of American Birds. By 

 Philip Lutley Sclater, Secretary to the Society. 



1. Campylorhynchus nigriceps. 



Supra fulvo-rufescens nigro transfasciatus : pileo toto nigro : 

 superciliis elongatis rufescenti-albidis, striga post-oculari nigra 

 subtus limbatis : alls nigris, harum tectricibus fulvo extus lim,' 

 batis, remigibus autem in pogonio externa maculis ovalibus 

 fulvis quater transfasciatis : cauda nigricante, rectricum po- 

 goniis externis et harum extimarum pogoniis internis obsoletius 

 fulvo transvittatis : subtus albidus, abdomine rufescente : rostra 

 pedibusque carneis, illius culmine nigricante. 

 Long, tota 6-5, alse 3'1, caudse 32, lostri arictu TO, tarsi I'O. 

 Hab. In prov. Verse Crucis Mexicana. 



I possess two examples of this species of Campylorhynchus, one 

 obtained by one of M. Salle's correspondents at Orizaba, and the 

 other from Senor de Oca's series collected at Jalapa. The latter is 

 manifestly in immature plumage. I have until recently considered 

 that they might perhaps be referable to an immature dress of C. ca- 

 pistratus, but such cannot be the case. The black head is distinctly 

 marked in both of my examples ; but there is no trace of the cha- 

 racteristic deep-rufous nape and upper back of C. capistratus, or of 

 the white termination to the black rectrices. The body is quite un- 

 spotted below, traces of blackish edgings to the feathers being appa 

 rent only in the younger specimen ; while in C. capistratus, junior, 

 there are decided round black spots. Though I should wish to exa- 

 mine further examples of C. nigriceps, I can entertain no doubt of 

 its distinctness from other known Mexican species of the genus. 



2. Campylorhynchus gularis. 



Supra brunneus, plumis omnibus nigra ocellatis, et medialiter alba 

 striatis : pileo tota et nucha brunnescenti-rufis unicolaribus : 

 superciliis latis et elongatis albis, striga post-aculari et altera 

 rictali utrinque nigricantibus : alispallide nigricantibus, harum 

 tectricibus sicut in dorso maculatis, remigibus autem solum in 

 pogonio externa maculis pallida brunneis regulariter trans- 

 vittatis : cauda nigricante, margine lata apicali alba : rectri- 

 cibiis quatuor intermediis pallida brunnea et nigricante amnino 

 tessellatis, praximis duabus in pogonio exteriore albido macu- 

 latis, duabus utrinque extimis in utraque pogonio maculis mag- 

 nis albis natatis : subtus lactescenti-albus, ventre rufescente : 

 gula immaculata ; ventre prcecipue laterali maculis rotundis 

 nigris asperso : rostra brevi plumb eo : pedibus pallide carneis. 



Long, tota 7 0, alse 2 '8, caudse 2*8, rostri a rictu 0*8, tarsi 0-8. 



Hab. In Mexico. 



Mus. P. L. S. 



I have a single specimen only of this Campylorhynchus, received 

 from Mr. Gould. It belongs to the group with rufous and black 

 heads, containing C. brunneicapillus, C. affinis, C. capistratus, C. 

 Jocosus, and C. nigriceps ; but differs from all in its pure wood-brown
