150 Mr. D. G. Elliot on the TrodiiiiclEe. 



not seen the types — sucli as C. euchloris (lleieli.), the descrip- 

 tion of which docs not enable me to form a satisfactory opinion 

 as to its validity, while the figure in his ' Troch/ p, 180, sp. 412, 

 is too j)oor to be of any service. I can distinguish three 

 groups or sections among the species of the genus Chloro- 

 stilbon as usually restricted, as follows : — those which have 

 the bill all black ; those with the bill with basal half of man- 

 dible licsh-colour, the rest black ; and those Avith the bill 

 all flesh-colour, excepting the point, which is black. I cannot 

 perceive any character sufficient to separate such species as C. 

 auriceps and C caniveti, generically, from C. angustipennis , 

 and have therefore not employed the term Chlorolampis pro- 

 posed by Cabanis for the former birds. The genus Pany- 

 chlora has but one section, the species being distinguished 

 from Chlorostilbon by having green tails, with the outer rec- 

 trices more or less pointed. The males of the species of these 

 two genera may be distinguished as follows : —
