belonging to the Genera Euphcmsa and Cyanorajia. 267 



This species is most nearly allied to Eupherujia egrcgia, but 

 can at once be distinguished tVoni it, as well as all the other 

 members of the ij;enus, by its tail. In cgngia the tour central 

 tail-leathers are black, and the remainder are black at the tips; 

 in the present species only the two median feathers are bronzy, 

 all the remainder being as descriljed above. This l)ird, together 

 with the following, was ul)tained in a small collection of birds 

 procured at Putla in the western part of ^lexico. This is the 

 third species now known of the genus Eup/wrusa, which for a 

 long tnnc was only represented by E. eximia. The species 

 are as follows : — 



1. Eupherusa eximia. Guatemala. 



2. E. egre(fia. Veragua. 



3. E. poUoccrca. Putla, Western Mexico. 



Two species, named respectively E. cupreiceps and E. nigri- 

 veufi-isj have been allotted to this genus ; but I thiidv that 

 they will hereafter be assigned to another genus {Thaumatias), 

 to which they seem more naturally to belong. 



Cyanoniyia viridifrons. 



Forehead and lines over the eyes dark green, metallic in 

 some lights and rather brilliant towards the nape ; centre of 

 crown dark grey ; u})pcr part of back and shoulders brilliant 

 light green ; lower part of back bronzy brown. AVings purple. 

 Upper tail-coverts and tail rich coppery bronze. Flanks grass- 

 green. Entire under parts pure Avhitc. Bill reddish, black at 

 tip. Total length 3j inches ; wing 2g inches, tail Ig inch, 

 bill jf inch. 



Ilah. Putla, Mexico. 



The present bird differs from all the members of this genus 

 by its peculiarly coloured head and tail, which do not in any 

 way resemble any other species of Cyayiomgia at present known. 

 It is perhaps nearest in its relationship to the C. violicej)Sy being 

 about the same size as that species ; but there is no trace what- 

 ever of the beautiful violet crown of that bird, and tlie tail is 

 also quite different. It is also from Putla, where the species 

 appears to be not imcommon. The present makes the seventh 

 species of this genus now known ; they are : — 



1. Cyanomyia quadricolor. Northern Mexico. 



2. C. violiceps. Western ]\Iexico, vicinity of Oaxaca. 



3. C cyanocephalus. Southern Mexico. 



4. G. Francicn. New Granada. 



5. C. guatemalensis. Guatemala. 



6. G. cyanicolUs. Peru. 



7. G. viridifrons. Putla, Western Mexico.
