ginatis; remigibus nigris; subalaribiis albo nigroque variis ; 

 mento et gula albidis; jugulo pectoreque superiore pure 

 cinereis ; gastrseo reliquo albo nigroque fasciato, fasciis albis 

 latioribus ; capitis lateribus cinereis ; lineola superciliari 

 antice alba,postice cinerascente; maxilla plumbeo-nigricante, 

 mandibula ad basin flavo-rubente, tomiis pallidis ; pedibus 

 brunneis. Long. 7-8"; rostr. a fr. 11'"; al. 4" 4"'; tars. 

 19'"; dig. med. c. ung. 17'". 



Tbis species has a cei-tain well-known aspect, but seems never- 

 theless to be undescribed. 



(4.) Nectarinia chalcea, n. sp. 



Valde affinis N. cuprece, sed certe diversa. In fun do aureo-vires- 

 cente chalceo resplendens, et sub certa luce nonnibil cupreo- 

 rubescens; scapularibus^ tergo, uropygio et supracaudalibus 

 magis conspicue cupreo-purpurascentibus ; abdomine, alis, 

 subalaribus et cauda, rostro et pedibus nigris. Long. 4^" ; 

 rostr. a fr. 9'"; al. 2" 3"'; caud. 1^"; tars. 7"'. 



After comparing this elegant Nectarinia with the nearly allied 



and well-known A^. cuprea of Senegambia and Upper Guinea, 



the difference at once becomes striking. The fiery-red and violet 



tints of the latter are almost entirely wanting in the more 



southern form, the head and back of which appear, under a 



certain light, to be green. The beak of N. chalcea is longer and 



stronger. 



(5.) IXOS TRICOLOR, U. sp, 



Fuscus ; capite intensius tincto ; abdomine albo ; subcaudalibus 

 dilute flavis ; subalaribus albis ; rostro et pedibus nigris. 

 Long. 7"; rostr. a fr. 7'" ; al. 3" 4'" ; caud. 3" 2'" ; tars. 

 9'". 



In the British Museum there are two specimens of an Ixos from 

 Congo, which I have introduced into the additions and connec- 

 tions to my ' System der Ornithologie Westafrica's,' under the 

 very erroneous name of Ixos awigaster, Vieill. (Lev. Afr. pi. 107. 

 fig. 2). This bird is somewhat larger than Mr. Monteiro's, but 

 resembles it in all other respects. They seem to be probably of 

 one and the same undescribed species, which belongs to the same 

 group as /. ashanteus, inornatus, arsino'e, xanthopygius, &c. 



(6.) Oriolus larvatus, Licht. 



Considerably smaller than the true South-African O. larvatus,
