plumage, agrees iu all essential particulars with G. aflHiiis, of which Connt 

 Berle])sch most obliginj;Iy sent me a skin colle('ted by Rockstroh in Guatemala. 

 The imder parts are uniform buff, paling into whitisli on chin and upper throat; 

 the lower tail-coverts blackish brown with lighter brown tips (not buff as in 

 G. califofiiidiiiia) ; the sides nf (lie foreueck luid chest only are marked with broad, 

 black shaft-stripes. Above, the crown and najie are black, with white apical spits ; 

 the back, instead of being pale bronze greenish, as in G. cali/orni'i/ius, is bright 

 mfescent-brown ; also the upper wing-coverts and inner secoudaries (tertials) are 

 metallic brown with coppery reflections, not greenish bronze. 



The naked space behind the eye, supposed to be lacking iu the type specimen, 

 is (levelojiod to the same degree as in other examples, but the taxidermist (who 

 probably took it for a deficiency) had very cleverly covered it with small feathers — 

 which, however, can be easily removed. 



There is, of course, the jjossibility that larger series may show the Guatemalan 

 birds to be snbspecifically separable from the typical Mexican form. The point 

 1 wish to emphasize is that (\tculuit relo.v belongs to the grouj) of Geococcyx 

 affiniii, and has no relation whatever to G. caU/oniianui (Less.).

R. ciireopijgua has been comjjletely lost sight of ever since it was described 

 by Gould in 1834, being not eveu mentioned either iu the second edition of 

 Gould's Monograph or in the Catalogue of Birds. The type specimen, kindly 

 forwarded to me for insjiection by Dr. Gadow, turns out to be an artefact: the body 

 is taken from ]{. lilellinas Licht., to which is very cleverly attached the head of 

 H. monili$ P. L. 8. Miill. (= crythiorhijwhus Gm.). It is only fair to state that 

 Dr. Gadow had already arrived at the same conclusion. 



The bill of the substituted head-jiortiou agrees in colour and shape with 

 li. vitellituis, of which a large series from the (Juianas and Trinidad has been 

 examined, while the bt)dy does not present any difference from the well-known 

 R. monilis. 



(Consequently R. citreoj/i/gii-i is to be eliminated from the list of existing 

 species. 



71. Aulacorhynchus * wagleri (Sturm)— a nomenclatorial Note. 



In 1835 J. Gould described and figured a Mexican species of Toucan from 

 a sini'le example iu the Munich Museum under the name Pteroglossus paconiniLs. t 

 The same specimen was made the type of a new species, Ptcroglossus ivagleri % 

 bv Sturm, six yetars afterwards. The purpose of this note is to show that the 

 correct specific name of the species in question is that given by Sturm.
