3. Xenops littoralis, sp. nov, 



Xenops genibarbis, Sclater, P. Z. S. 1860, p. 293. 



Similis Xenopi genibarbi ex Brasilia, sed statura majore, gula 

 minus albescente, corpore subtus magis olivaceo et dilutiore 

 distinguendus. 



Long, tota 47, alse 2*5, caudse 1-9.. rostri a rictu 0'6. 



Hab. In reip. ^Equatorianae regione littorali. 



This Xenops is a climatic variety of A'^. genibarbis of Brazil, but 

 has apparently as good claims to separation as X. mexicanus, its 

 Mexican representative, or as Xenops heterurus. Cab. et Hein., from 

 X. rutilus. It is a larger, stronger bird than X. genibarbis, and is 

 lighter and more olivaceous in its coloration belovr. The wing-band 

 which crosses the middle of the primaries and secondaries is broader 

 and much deeper in colouring in the present bird, but the general 

 coloration does not materially differ from that of the Brazilian form. 

 My specimens were obtained by Mr. Eraser, at Esmeraldas, in No- 

 vember 1859. 



4. Sphenopsis ignobilis. 



Sphenopsis, genus novum ex familia Dendrocolaptidarum, affine 

 Philydori et ejusmodi formis plerumque Anabatis dictis. Rostrum 

 brevius quam caput, seque altum ac latum, conicum, validum, gonyde 

 recta : alae modicse, dimidium caudse attingentes : pedes ut in genere 

 Philydor e, sed tarsis breviusculis. 



Typ. et sp. unica S. ignobilis, sp. nov. 



Cinerascenti-olivacea, subtus paulo magis rufescens : superciliis a 

 /rente obsolete rufescentibus, alis caudaque rufescente fulvo 

 limbatis : rostra plumbeo : pedibus fuscis. 



Long, tota 5-0, alse 2-8, caudse 2*7, rostri a rictu 0'7, tarsi 0*75. 



Hab. In Brasilia. 



I have long had a single specimen of this little bird in my collec- 

 tion, under the manuscript name which I now bestow upon it, and 

 have never seen a second. It is remarkable for the short, straight.
