restlessly and briskly about among the fallen bamboo straws, in 

 the numerous hiding places of which it knows how to conceal it- 

 self. Once or twice I saw it fly about 10 yards or so, but then 

 suddenly it vanished into the confusion of the plants in the dark 

 lanes of the baraboo-kingdom. The protective colours of the 

 plumage makes it also extremely difficult to discover. It occurs 

 on Elgon at an altitude of 8000 to 9500 feet. 



This bird has by Reicheuow (op. cit.) been made a 

 synonym of C. reichenowi (Hartl.), but Ogilvie-Grant (Bull. 

 Brit. Orn. Club. 1907, p. 42) has shown that it is "a perfectly 

 distinct species", which was described by Sharpe (Bull. Brit. 

 Orn. Club, 1902, p. 8) from Ruwenzori. Bannermanu (Ibis, 

 1915, p. 657) says that "the males of C. reichenowi and C. ocu- 

 laris are indistinguishable". At a later date Ogilvie-Grant 

 brought home a large serie of ocularis from Ruwenzori and the 

 same writer states (Zool. Res. Ruw. Exp., 1910, p. 296) that 

 there "it frequents the rough country below the forest- line, 

 especially old sites of cultivation and crops of millet", L o n n - 

 berg (Birds, coll. Sw. Zool. Exp. B. E. A., 1911, p. 106) has 

 found Cryptospiza in the dark forests and v. Someren (Nov. 

 Zool., 1918, p. 281) has also met with it in the same kind of 

 locality. 



After comparing my specimens with those in the Berlin 

 Museum I have come to the opinion that Ogilvie-Grant is 

 quite right. Further, my speciniens are exactly like others found 

 in Berlin bearing the name of C. ocularis and originating from 

 Ruwenzori and Uganda, but they also agree rather well with 

 Lonnberg's salvadori specimens. 



These two specimens are alike and have the head and 

 interscapulur region dark greyish olive-green. {C. reichenowi is 

 much lighter) and in this they approach C. salvadori. Even 

 this race is very closely related to the latter in that the male 

 is without the red on the sides of the head. Reicheuow, 

 it is true, writes (Vogelf. Mittelafr. Seengeb., p. 333) that he 

 has found that d*cf of C. salvadori also has red on the sides 

 of the head, but L o n n b e r g (op. cit.) shot two males by the 

 Escarpement in B. E. A., both of which were without this red 

 patch. The male specimen has, besides, swollen testes, so that 

 there is not the least doubt as to the correctness of the sexing. 



C. ocularis differs rather sharply from C. salvadori, that 

 is, in the latter the head and interscapular region are distinctly 

 brownish green, while in the former these parts are as described 

 above. 



The chin is lighter than the other parts of the lower sur- 

 face and is predominantly grey (with a pale yellowish green 

 wash). Lower parts olive grey. 



Without material for comparison the species and races of 

 the Cryptospiza genus are very difficult to keep apart and 1
