rhynchus tricarunculatus , carrying the range of this species 

 much further north than has been hitherto recorded. 



Fam. Dendrocolaptid^e. 

 Several specimens of a Xiphocolaptes agree with the true 

 -I X. emigrans of Guatemala. 



Fam. TROCHiLiDiE. 

 Thirteen species are represented of this family ; of these 

 we find the following northern upland species all strictly 

 agreeing with Guatemalan specimens, viz. : — Eupherusa 

 eximia, Cyanomyia guatemalensis, BasUinna leucotis, and 

 TUmatura dupont'i, and two female examples which we believe 

 to belong to Abeillia typica. Microchera pjarvirostris , already 

 noticed in Chontales, is also represented. Other species are 

 more widely spread in Central America, and lastly we have a 

 beautiful new species of Delattria, which we propose to call 



Delattria sybilLtE, sp. nov. 

 D. viridipal/eiiti proxime affinis, sed pectore et hypochondriis 

 viridibns nee albis gula fere concoloribus ; tectricibus 

 subcaudalibus et rectricibus pallide griseis et dorso imo 

 viridi nee cupreo tincto facile distinguenda. Long, tota 

 4*5 poll. Angl., alee 2*6, caudse rectr. med. 1'3, rectr. 

 lat. 1'7. ? adhuc ignota. 

 Hab. Nicaragua, Matagalpa [W. B. Richardson). 

 Mr. Richardson has sent us six male specimens of this 

 beautiful species, all obtained near Matagalpa at an eleva- 

 tion of about 4000 feet above the sea-level. 



The bird is a true Delattria, allied to D. viridipallens, with 

 the characteristic postocular white stripe. 



Fam. PiciD^. 

 "^Colaptes mexicanoides is represented by several specimens 

 which agree closely with others from Guatemala, from which 

 country alone this bird has as yet been recorded. 



Fam. RHAMPHASTIDiE. 



We also find specimens of the Guatemalan and Mexican 

 -f Aulacorhamphus prasinus precisely like the typical form.
