In his " Descriptions of some new Species of Birds belonging chiefly 

 " to the rare Genera Phytotoma, Gmel., Indicator, Vieill., and Curso- 

 " rius, Latham.," Mr. Leadbeater has contributed from his valuable 

 collection several important additions to our ornithological list. First of 

 these is the Phytotoma ferreo-rostre, Phyt. " brunneum, capite, gula, 

 " caudaque supra rufis; rostro nigro, crassissimo ;" the extraordinary 

 dimensions of whose bill considerably exceeding both in breadth and 

 height the greatest breadth of the skull, and the peculiarity of some 

 other characters, have induced Mr. Leadbeater to believe that it will 

 eventually be found to constitute a distinct group from that with which 

 he has at present associated it. The Myioihera Yarrellii is thus charac- 

 terized : Myioth. " supra brunnea ; striga supercihari, thorace, crisso, 

 " guttisque alarum pallid^ fulvis, abdomine albo ; striga per oculos 

 " tectricibusque nigris." k third species is a Wren from Chili, the Ty- 

 rannulus Vieilloti, Tyr. " supra viridi-olivaceus, corpore subtus stri- 

 " gaque superciliari utrinque flavis ; capite cristato, alls, cauda, macu- 

 " laque utrinque abdominali atris ; regione auriculari atrocaerulea ; ca- 

 " pite summo crissoque roseis; mento strigaque alarum albis." The 

 fourth is an African species of the New Holland genus Pardalotus, Pard. 

 Afrkanns, Pard. " supra virescenti-ohvaceus, subtijs flavescenti-albi- 

 " dus ; alls caudaque nigris, illis albo guttatis, hac albo terminata." 

 A brief indication of the species hitherto noticed as belonging to the ge- 

 nus precedes the description of three species of Indicator, Vieill. These 

 are, L Ind. Le Vaillantii, Ind. " oHvaceo-brunneus, subtijs albidus, 

 " gula pectoreque flavo-variegatis ; rectricibus duabus mediis fusco- 

 " brunneis, caeteris albis fusco-brunneo notatis." 2. Ind. Buphagoides, 

 Ind. " olivaceo-fuscus, abdomine albido ; alis dorsoque infimo flavo 

 " variegatis ; rectricibus quatuor mediis olivaceo-brunneis ; rostro brevi, 

 " crasso." 3. Ind. Sparmanni? Ind. " olivaceo-brunneus, gula pec- 

 " toreque albido maculatis ; abdomine crissoque albidis, brunneo linea-
