cinereous, the sides of the head are exactly alike, and the legs pale fleshy brown. 

 The Venezuelan bird differs, however, at a glance by the deep yellow (instead of 

 white) under parts. 



Chlorospingus reyi Berl. * bears a remarkable likeness to B. griseiceps, but 

 may be distinguished by its less depressed, more curved bill, by the absence of 

 rictal bristles, by lacking the blackish mixture about the forehead, the white snpra- 

 loral streak and chin-spot, as well as by having the sides of the head olive-yellow 

 (not cinereous). There are two specimens of this rare species in the Tring Mnseam : 

 an adult female from El Escorial, February 20, 1896, and an adult bird from 

 M6rida, without date and sex, obtained by S. B rice no.

There has been considerable uncertainty about the name C. jlaviventris, which 

 was originally based upon two specimens : one from Trinidad in Sir William 

 Jardine's possession, and another supposed to be from Bolivia in the Strickland 

 Collection. The former is apparently lost, it being neither in the British nor in 

 the Tring Museum, while the second example is still preserved in the Cambridge 

 Museum, whence it has been kindly forwarded for my inspection by Dr. Hans 

 Gadow. It is a skin in good condition, labelled as follows : " Coll. H. E. 

 Strickland, No. 943 b. Tachyphonus luctuosus, Catalogue p. 194." The inscription 

 (in Strickland's own handwriting) of the old label reads: "Arremon-Chlorospingus. 

 Hab. Brazil ? Date 1852. Obt d . from Argent," and on the back : " C. Jlaviventris 

 new. Arremon No. 107 a." 



Its dimensions are : wing 63 ; tail 57| ; bill 12| mm. 



This example, which answers exactly to Sclater's original description, agrees with 

 several females of T. luctuosus from Bolivia, except in being slightly larger, with 

 a somewhat longer, slenderer bill, and in having the crown rather clearer cinereous. 

 These insignificant differences are no doubt individual. It appears to be one of 

 Bridges' skins, showing the same handsome " make-up " as several Bolivian 

 specimens, obtained by that traveller, in the British Museum. 



Salviu f identified C. Jlaviventris with C. albitempora Lafr., considering No. 

 956 a of the Strickland Collection as the specimen referred to by Dr. Sclater. 

 Dr. Gadow having obligingly sent me the bird in question, J I can positively state 

 that this is a mistake. Dr. Sclater says of G. Jlaviventris : " capite cinereo, viridi 

 paulum apparente " and " gula albescenti-cinerea, abdomine toto flavo " ; whereas 

 No. 956 a has the top and sides of the head dark coffee-brown, the throat bright 

 isabelline, and the whole middle of the belly white, the flanks only being dull 

 yellowish olive-green ! It is, therefore, evident that No. 956 a cannot have been one 

 of the types of C. Jtaviventris. But it does not belong to C. albitempora, either, 

 differing by its isabelline (not whitish) throat, more buffy yellow chest-band, and 

 paler, less blackish crown. In all these particulars it closely resembles the type 

 of C. fulvigularis Berl., forwarded for examination by my friend Count Berlepsch,
