482 PRIONOPS PLUMATA 
of this genus are very similar in habits, for Mr. Neumann 
observed that in this species they are very like those of 
P. poliocephala. 
The only example in the British Museum is the one 
obtained by Lord Delamere on the Kedong River already 
alluded to.

Similar to P. poliocephalus, from which it differs in having a long crest 
of white decomposed feathers which reach a length of about 1:5 inches, 
springing from the centre of the crown and directed backwards; the white 
nape band is also wider, and the stiff forwardly directed frontal-feathers 
longer and purer white. ‘Iris dark greenish-grey with an outer ring 
yellow, fleshy ring round the eye aurora yellow, bill greenish-black, 
feet pale venetian-red.”” Length 9°d inches, wing 4:6, tail 3-8, culmen to frontal 
feathers 0:5, tarsus 0°9. Gunnal, g, 29. 4. 09 (Ansorge). Female, wing 4:6 
(Ansorge). 
Young bird. Has no crest, and the crown washed with pale brown; the 
back is dusky brown with traces of paler edges to the feathers. Fleshy ring 
round the eye dark olive green ; feet ochre yellow. Gunnal (Ausorge). 
The Long-Crested Helmet Shrike ranges from Senegambia 
into northern Nigeria. The species was first described and 
figured by Levaillant, who called it the ‘‘ Geoffroy,” after the 
traveller, M. Geoffroy de Villeneuve, who first brought it from 
Senegal, and Shaw’s and Vieillot’s names were founded on 
Levaillant’s description. Marche and De Compiégne collected 
specimens at Deine and Ponte near Cape Verde, and it is 
apparently nof uncommon throughout its range both inland 
and along the coast. It has been procured on the island of 
Bulama by Barahona, and from the Los Island there is a
