the breast is not greyer than in C. hartlaubi, but greener ; and he entirely omits to remark the 

 characteristic form of the bill. Under these circumstances I shall omit Prince's Island as a 

 locality for this species, as not resting upon sufficiently good authority. 



The type specimen was collected on Fernando Po by Fraser, according to whose 'notes " two 

 other specimens only were seen, but could not be obtained. They had a straight dart-like flight, 

 appeared of a long slender form, and ran actively up the small branches in search of insects. Bill 

 olive-yellow at the base of the lower mandible, legs olive-green, irides hazel." 



On the continent it appears only to have been met with in the Gaboon district, where 

 Du Chaillu collected specimens at Cape Lopez and on the banks of the Camma and Ogowe rivers. 



According to Mr. Cassin " the female is smaller than the male, but very similar in colours. 

 The young male like the female, but with the colours duller and of a darker green in all the 

 plumage, no axillary tufts." 



We enter these notes of Mr. Cassin, as the species is very rare in collections ; and the few 

 specimens we have been able to examine have no indication of the sex, excepting in the two 

 specimens which we have here figured and described, both of which are males. They were 

 procured by Du Chaillu on the Camma river, and now form part of the Marquis of Tweeddale's 

 collection.
