W. E. OGILVIE-GEANT — AVES. 420 



C. f. clarus is founded on younger specimens, which are paler and of smaller 

 dimensions. 



The five specimens mentioned above measure as follows : — 



According to Dr. Reichenow, the two first-mentioned specimens should be referred 

 to C. fossei and the remaining three to C.f. clarus. 



Two eggs of this species were procured at Mokia on the 10th of July by Mr. R. B. 

 Woosnam. They have the usual Nightjar type of coloration, and measure respectively 

 TloxO-S and TOxO'S in. One example will be found figured on Plate XIX. fig. 21. 



[The Mozambique Nightjar was numerous on the plains around the south end of 

 Ruwenzori. They were often to be seen in the evenings flying in and out close to 

 the ground among the acacia-trees. They were fond of settling on the euphorbia- 

 trees to make their "jarring" cry. — B. B. W.~\

 Type of the species.'] 



This species is most nearly allied to C. frcenatus Salvad., but is altogether darker, 

 especially on the underparts, the belly and under tail-coverts, like the breast, being 

 entirely barred with black and buff. The white spot on the inner web of the first 

 primary is small, situated on the margin, and does not extend more than halfway 

 across the web ; the two outer pairs of tail-feathers have the terminal half white 

 (2'4 inches deep on the outer pair), the brown on the margin of the outer web 

 extending almost to the tip ; a group of buff spots on the middle of the chest. Iris 

 dark brown ; bill black ; feet brown. Total length ca. 9"0 inches ; wing 6-2 ; tail 4 - 25 ; 

 tarsus 0"66. 



A second male example, which is no doubt of this species, was procured in Likipia by 

 Mr. L. C. Harwood when collecting for Lord Delamere. The tail of this bird is missing. 



C. pectoralis Cuv., from S. Africa, is another closely allied species, but lacks the 

 group of buff spots on the chest ; it, however, resembles C. ruwenzori in having the 

 primary-quills from the 5th inwards black barred with chestnut. 



[A few of these Nightjars inhabited an open ferny ridge on Ruwenzori at an elevation 

 of from 8000-9000 ft. This species was not obtained on the plains below. — B. B. W.~\
