There is a distinct white patch behind the ear-coverts, the 

 rectriees are tipped with white, and the crown, sides of 

 the head, including the ear- coverts, are black. 



Wings : males 85-90 mm., majority 87 ; females 80-83, 

 majority 82. 



Type. Male in Dr. van Someren's Coll. Changamwe, 

 N. of Mombasa, 19/11/18. Wings 87 mm. 



Ohs. I have a large series of topotypical P. micrus 

 Oberh., which this bird is not. Further, it was submitted 

 to this authority, who declar6d it distinct. I indicated its 

 distinctness in my paper, Nov. Zool. xxix., April 1922. 



A series of 42 skins was collected- 



Range, The coastal belt from the Kilifi River, Malindi, 

 south to Shinioni. Inland along the railway-line to 

 Samburu. 



Dr. VAN SoMEREN also sends the following description of 

 a new species of Linurgus from Kenya : — 



Linurgus keniensis, sp. nov. 



Adult male nearest to L. elgonensis (mihi), but darker 

 above ; mantle, rump, and tail more olive, not so yellow. 

 Underside not so pure yellow. There is no yellow collar 

 separating the black of the nape from the olive of the 

 mantle, as there is in L. elgonensis. 



Adult female differs from female of L. elgonensis in a 

 similar way, i. e. it is generally darker. 



There is little difference in wing-measurements : L. elgo- 

 nensis 70-73, L. keniensis li-Tl mm. 



Igpe. Male adult in Dr. van Someren's Coll. Meru 

 Forest, N. Kenia, 27/12/20. 



Distribution. Apparently limited to Mt. Kenia. 



Ohs. This bird stands intermediate between L. elgonensis, 

 o£ which I have nine skins, and L. kilimensis, of which I 

 possess six. 



Except for the fact that the species of Linurgxis are 

 so widely separated and have such restricted ranges, one 

 might suggest that they were merely geographical races of 

 L. olivaceus (Fras.).
