Forest, and S. grandis O.- Grant, from the coastal districts 

 of Biitish East Africa. 



As in S. vulpina the buff markings on the basal half of the 

 inner webs of the primary quills are sharply denned from 

 the dark terminal portions, while in S. grandis they grade 

 imperceptibly into them. 



The comparative measurements are as follows : — 



Hab. Victoria Nyanza District : Entebbe and Mbarara, 

 in Ankole. 



Type in the British Museum : . Entebbe, 10. xi.05. 

 E. Degen coll. 



Obs. My collector obtained a second male example of this 

 Flycatcher at Mbarara, in Ankole, on the 14th of October, 



Caprimulgus ludovicianus, sp. n. 



Adult. Most nearly allied to C. inornatus, Heugl., which 

 it resembles in all the more striking characters, such as 

 the white markings on the primaries, the four outer quills 

 having a white patch on the inner web which extends on to 

 the outer web of the second, third, and fourth ; and the two 

 outer pairs of tail-feathers have the terminal half (about 

 55 mm.) white on both webs. 



It is, however, easily distinguished from C. inornatus by 

 its much larger size and the more rufous ground-colour of 

 the upper- and underparts, the median and greater wing- 

 coverts being very conspicuously spotted at the extremity 

 or tipped with light red. Wing 174 mm. ; tail 130. 



In C. inornatus the measurements are : wing 155 mm. ; 

 tail 115. 



Hab. South-west Abyssinia. 



Obs. I have presented the type of this species to the 

 British Museum. Adult no. 43. South Abyssinia.
