HARTLAUB AND FINSCH ON LOBIOSPIZA. 817 fibrous expansions from the humeral muscles, more especially the great pectoral, masto-humeral, the subscapularis, the infraspinatus, and deltoid. 2. O n Lobiospiza notabilis, a remarkable new Finch from the Navigator's Islands. By Dr. G. H A R T L A U B , F.M.Z.S., and Dr. O. F I N S C H , C.M.Z.S. (Plate XLIX.) In a collection of birds sent for determination from the private museum of Messrs. Johann and Cesar Godefroy of Hamburg, we received a little Finch, which proves to be new to science. The single specimen was collected by the well-known explorer of the Central Pacific Islands, Dr. Eduard Graffe, in the island of Upolu. W e congratulate the indefatigable traveller upon this discovery, it being the more important and interesting inasmuch as, until now, among the extensive series of Fringilline birds no member has been found having the gape ornamented with wattles. The "Wattled Finch," therefore, merits, in our opinion, to rank as the type of a new genus, which we propose to call LOBIOSPIZA, gen. nov. Char. gen.-Rostrum robustutn, integrum, rotundatum, basi dilatato-incrassatum, culmine rotundato ; naribus occultis ; rictu caruncu-lato, caruncula rotundata, verrucis duabus obsita. Alee longiusculce, remigibus tertio et quarto cequilongis; primo brevissimo (3'") Cauda brevior, mollis, attenuata; rectricibus augustatis, debilibus, apicibus subacuminatis. Pedes majusculi, graciles ; tarso caligato; digito interno et externo cequilongis; unguibus acutis, compressis, valde arcuatis. The most striking feature in this singular genus is, as already mentioned, the presence of wattles. These are composed by the margins of the angle of the mouth, which are swollen and prominent, forming a rounded leaf-like small caruncle, which is besides ornamented with two small prominent granule-like verrucse. These caruncles resemble those of Heteralocha; but in the latter they are considerably further extended, and smooth. The remaining generic characters agree with those of the nearest ally, Amblyura, Beichb., except iu having the bill proportionally stouter and more fornicated. LOBIOSPIZA NOTABILIS, sp. nov. (Plate XLIX.) Diagn.-Tota obscure et obsolete ceerulescens, plumis basin versus nigricantibus: subtus pallidior; remigibus et rectricibus nigris, ceerulescente marginatis; caudce tectricibus superioribus fuscescentibus ; plumulis supranasalibus conspicue nigricantibus; rostro flavida* apice nigricante ; pedibus infuscatis. |
