610 On the genus LnmY)Yih\s. [Tbis, 



L. vara Rothsch., Hart., & Kleinschni., is apparently the 

 less rare of the two, and was seen singly or in pairs along 

 small forest-brooks or in wooded swamps. Our two speci- 

 mens, representing both sexes, have been compared with two 

 specimens from the River Muni and one from Liberia, in the 

 Museum of the Philadelphia Academy of Natural Sciences. 

 While these three West African birds all have the abdomen 

 somewhat darker than in those from the Ituri, there seem to 

 bo no differences of importance between them. 



Lamprlhis. olivacea (Du Bus) was only observed on one 

 occasion, when a pair were flushed from the ground and amid 

 dense undergrowth, some little distance back from the bank 

 of the Ituri. Our single specimen, a male, shows no evidence 

 of immaturity and measures : wing o35 mm., tail 133, 

 culnieu 10(j, bill from posterior angle of nostril 94, tarsus 70, 

 middle toe with claw 69. 



From the original description and plate of Du Bus there 

 seemed to be no doubt of its identification as L. o. olivacea, 

 and Mr. Bannerman's recent notes * confirm my opinion. 



La))ij)ril>is akelejjonim (Chapman) j ii? really the eastern 

 representative of L. olivacea, being larger, with wing-coverts 

 shining green (as opposed to a more copper}^ tinge in our L. o. 

 olivacea), and its plum.igi? of a warmer brown tone through- 

 out. Notwithstanding that the tips of the wings Jire badly 

 worn, they measure 358 mm. in the male, 362 in the female. 

 The specimens of Lamprihh with which Dr. Chapman 

 compared them, from the Philadelphia Academy of Natuml 

 Sciences, were really those of L. vara mentioned above, but 

 wi'ongly labelled as L. olivacea. 



Tliat the extent of bare skin about the face is a good 

 diagnostic character in Lampribis, and not dependent upon 

 age, is well shown by the downy young of L. akeleiforum, 

 for the shape of the naked patches, only a few days after 

 hatching, is exactly the same as that of their parents.
