Characters of Eight New Species of American Birds. By 

 Philip Lutley Sclater, Secretary to the Society. 



1. Campylorhynchus nigriceps. 



Supra fulvo-rufescens nigra transfasciatus : pileo toto nigra : 

 superciliis elangatis rufescenti-albidis, striga ptast-aculari nigra 

 subtus limbatis : alis nigris, harum tectricibus fulva extus lim- 

 batis, remigibus autem in pogonio externa maculis ovalibus 

 fulvis qiiater transfasciatis : cauda nigricante, rectricum po- 

 goniis externis et harum extimarum pagoniis internis absoletius 

 fidvo transvittatis : subtus albidus, abdomine rufescente : rostra 

 jjedibusque corneis, illius cubnine nigricante. 

 Long, tota &'i), alse 3'1, caudse 3'2, rostri a rictu 1*0, tarsi 1*0. 

 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 Seiior 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 capistrutus, 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 kno^vn Mexican species of the genus. 



2. Campylorhynchus gularis. 



Supra brumieus, plumis omnibus nigra ocellatis, et medialiter alba 

 striatis : pileo toto dt nucha briinnescenti-rujis unicaloribus : 

 superciliis latis et elangatis albis, striga post-oculari et altera 

 rictali utrinque nigricantibus : alis pallide nigricantibus, harum 

 tectricibus sicut in darsa maculatis, remigibus autem solum in 

 pogonio externo maculis pallide brunneis regulariter trans- 

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

 cibus quatuor intermediis pallida brunnea et nigricante omnino 

 tessellatis, proximis duahus in pogonio exteriare albido macu- 

 latis, duabus utrinque extimis in utroque pogonio macidis mag- 

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

 gula immaculata ; ventre praecipue laterali maculis rotundis 

 nigris aspersa : rostra hrevi plumbea : pedibus pallide corneis. 



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

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
