BESSONORNIS SUBRUFESCENS INTERCEDENS Cabanis. 



Bessoiiornis interredms Cabanis, Jouni. f. Ornitli., IsTs, pp. 205 218 (Kitui 

 Ukamba, Tiritisli East Africa). 



A single adult male collected by Dr. W. L. Abbott at 5,000 feet 

 altitude on Mount Kilimanjaro, July 22, 1888, was rcccntlv recorded 

 as Cossyp/ia heu.glliii intermedm."' The present opportunity of com- 

 paring it with a series of true Bemmoniis (= Cos.si/pha) heugUni lnh'r- 

 media^' from Mom))asa shows that it belongs to the other species (/>. 

 rufeseeihs) which differs from IL heugUni in its darker and slate-col- 

 ored instead of olive-brown upper surface; l)lackish middle tail- 

 feathers, and less extensive white superciliary stripes that do not 

 meet across the forehead as in lieaglini. The original description of 

 Bessonornin KnhriifeHe^'ux'' was based on specimens from Caconda, 

 Angola, and therefore represents the West African form, from which 

 the Bessornis intercedens of Cabanis ^ seems to differ sufficiently in 

 its smaller size and less l)lackish tail-feathers to stand as a subspecies. 



Our attention has been called b}' Mr. W. E. C Todd to the fact 

 that Oos.syp/ia/ the name in common use for the present genus, is 

 preoccupied in entomology (Coleoptera) b}^ CoxxyjjJtns Fabricius/ it 

 therefore will have to give wa_y to BeHsomn'nis Smith. f'

CISTICOLA HYPOXANTHA Hartlaub. 



Cisiicola hypoxanfha ITartlauh, Proe. Zool. Soc. Lond., 1880, p. 624 (Magungo, 

 northeastern end of Lake Albert Nyanza, British East Africa). 



This species, based upon a single immature specimen, has hitherto 

 ])een almost uniformly synonymized with Cixticola rufa, notwith- 

 standing its widely separatfnl range. Four specimens, however, col- 

 lected by Mr. Doherty at Mombasa, and recorded by Doctor Holland^' 

 as " Olstieohi off. ruf^v (?), sp. nov. (?) vel. rufir subspecies," prove 

 beyond much doubt that it is quite distinct, difi'ering from OlMlcola 

 rnfa of western Africa in its less uniform upper surface, the pileum
