The type of this species, now in the Derby Museum at Liverpool, is stated to have 

 been obtained at Coban in Guatemala ^ ; but as no other examples for a long period 

 came under our notice, we were inclined at one time to doubt the correctness of the 

 locality ^ ^. There was, however, in 1873, a Guatemalan specimen in the Museum of 

 the Sociedad Economica de Guatemala, and more recently a specimen from Coban was 

 submitted to us by M. Boucard, thus confirming the original statement. It must, 

 however, be an exceedingly rare bird in Guatemala, as we have never found another 

 example amongst the thousands of skins from that country that we have examined. 

 Southwards of Guatemala its presence has been recorded in several parts of Central 

 America, and in the State of Panama Arce and M'Leannan obtained a few specimens. 

 In Colombia, Salmon found it near Eemedios, in the State of Antioquia^, and this 

 point seems to be the southern limit of its range. The two specimens from his 

 collection before us are perhaps not quite adult, and have a greyish tinge on the throat, 

 head, and lower back, not found in our Central-American examples. The dark spots 

 on the under surface and the dark tips to the wing-coverts appear to be characteristic 

 of the male sex ; the flank-tufts are also of a reddish-orange hue in the female, those 

 of the male being clearer yellow. 



This species, like Lathria unirufa and lApaugus Jiolerythrus, can be distinguished 

 from the rest of its congeners by the cinnamon colour of its plumage. 



LIPAUGUS. 



Lipaugus, Boie, Isisj 1828, p. 318 ; Scl. Cat. Birds Brit. Mus. xiv. p. 356. 



There are three species in this genus which have their representatives, so far as their 

 coloration is concerned, in the genera Lathria and Aulia ; but they are of smaller size, 

 the rictal bristles are much more fully developed, and the tarsi beneath are rough 

 towards their proximal end ; the nostrils, too, are more hidden by the supra-nasal 

 feathers.
