outer margins ; the two middle tail-featliers olive-green with, 

 blackish tips, the other tail-feathers hlack with yellow tips, 

 which become more extended on the outer ones, so that the 

 outermost tail-feathers are half yellow ; under wing-coverts 

 pale yellow. Iris dark brown ; wattle at the gape orange ; 

 bill and feet black. Culmen 13 mm.; wing 100; tail 85 ; 

 tarsus 18. 



Adult female. Head dusky brown mixed with yellow, the 

 latter colour prevailing on the forehead, while on the chin 

 there are also some grey feathers ; the rump is not so yellow 

 as in the male; and all the yellow parts are of a paler shade, 

 with no orange on the breast. The iris, bill, feet, and gape- 

 wattles are coloured as in the male ; but the wattles are 

 small and hardly show in the dried skin. The wing and 

 tail measure a little less than in the male, the bill and tarsus 

 the same.

Obs. These birds were not uncommon at the place where 



I collected, on the Bumba River, in the Njiem or Zima 



Country, near the eastern border of this colony. Besides 



these I obtained a second pair ; a male was also obtained at 



a place on the River Ja, on the way to the Njiem Country. 



These birds feed on caterpillars ; their note was not heard. 



They have a remarkable external resemblance to Oriolus 



Icetior, which was a common species everywhere. 



Dr. Sharpe remarked that the genus Lobotus was previously 

 represented on the Gold Coast by a single species, L. lobatus, 

 of which there were two male specimens in the British 

 Museum. The species described by Mr. Bates, from 

 Cameroon, differed from L. lobatus in having the underparts 

 entirely yellow, without any chestnut-colour on the breast, 

 the nape and rump being likewise golden-yellow, without 

 any chestnut. 



Mr. Charles Chubb communicated, through Dr. R. 

 Bowdlek Sharpe, the following description of a new species
