the Vultur occipitalis, *' Vult. auchenio, dorso, cauda, pectore, tec- 

 ** tricibus, fusco-nigricantibiis; pileo cristato, jugulo, abdomine, et 

 " remigibus secundariis albis ; rostro sanguineo ; ceromate nigro; pedi- 

 *• bus rubris." It lives solitary or in pairs in the eastern dependencies 

 of Abyssinia, and appears to extend far into the interior of Africa. 



The Insessorial Birds are numerous. Of these the first is the Capri- 

 mulgus infuscatus, " Capr. corporis colore ex fusco rufescente; plumis 

 " omnibus striis subtilibus nigris undulatis ; gula, fascia mentaU remi- 

 " gumque, rectricibusque duabus extemis albis." Of Ixos, Temm., 

 fTurdoides, Ejusd.,) four species were obtained, two of which are 

 described as new, the Ixos leucocephalus, " Ix. rostro nigro, capitealbo; 

 ** alarum caudeeque color umbraceus, plumarum laxarum nuchee, 

 " auchenii, et interscapulii dilutior; gastrseo e fusco candicante; gula 

 " maculis albescentibus varia:" and the Ixos plebeius, " Ix. rostro nigro, 

 " corpore supra umbrino, gula alba, jugulo et pectore fuscescentibus, 

 " plumis maculis albis terminatis, abdomine ex fusco candicante.'* The 

 former of these is found plentifully in Sennaar, and the latter, which is 

 probably migratory, occurs in troops in Kordofan during the winter. 

 The next species, the Sylvia Ruppellii, Temm., from the Red Sea, has 

 been previously figured in the Planches Coloriees. Of the genus Malurus 

 four are given : the Mai. Acacice, " Mai. corpore coloris ex ochracec 

 " isabellini; capite cinerascente, obsolete fusco striolato; gula alba; 

 " rostro pedibusque flavis," which has been included in Lichtenstein's 

 Catalogue as a species of (SpAenwra: the Mai. squamiceps, " Mai. corporis

 damans, " Mai. fronte et vertice ex albo nigroque variegatis: corpore 

 " supra helvolo ; infra subflavo ; tectricibus nigris, albo limbatis:" and 

 the Mai. gracilis, " Mai. corpore supra ex cinereo olivascente, subtus 

 *' albescente : in pileo, cervice et dorso maculae oblongse, obsolete fuli- 

 " ginosae." The latter is the Sylvia gracilis oi Lichtenstein's Catalogue, 

 and an uncoloured figure of it has been given in the Description de 

 I'Egypte. TheEmberiz(JB are three: the Emb. ccBsia, " Emb. capite, 

 " nucha, pectore caeruleo-cinerascentibus; gutture, gastrseo cinnamo-
