The following is the nomenclature and distribution : — 



LOPHOCEROS CAMURUS CAMURUS. 



Tockus camurus Cassin, Proc. Acad. Philad. viii. p. 3i9 

 (1857) : Cape Lopez. 



Seventeen examples examined in B.M. from Gaboon, 

 Cameroon, Ifcuri, and Welle districts of Belgian Congo. 



LoPHOCEROS CAMURUS PULCHRIROSTRIS. 



Buceros pulehrirostris Schlegel, Ned. Tijd. Dierk. i. p. 74, 

 pi. iv. (1863) : St. George d'Ehnina, Gold Coast. 



Eight examples in B.M. examined from Liberia and the 

 Gold Coast. 



CORYTHORNIS CRISTATA. 



The Malachite Kingfisher, inhabiting the Island of Principe 

 in the Gulf of Guinea, is remarkably distinct from that of 

 the mainland. This last-named is now known as Corytliornis 

 cristata cristata Pallas (nee Linn.) and was formerly known 

 as C. cyanostigma (see C. Grant, ' Ibis,^ 1915, p. 263). The 

 Prince's Island bird is called C. galerita (Miill.) in the 

 B.M. Catalogue (xvii. p. 166), and the synonyms given 

 are Alcedo cceruleoceyliala Gmel. and A. cyanocephala Shaw. 

 Both these and Miiller's name are all founded on Daubenton's 

 plate (PI. Eulum. no. 356, fig. 1). 



An examination of this plate shows that it undoubtedly 

 represents the typical Malachite Kingfisher and not the 

 Prince's Island bird, and Buffon's letterpress informs us 

 that the bird had been obtained from Senegal and 

 Madaoascar. It does not therefore seem advisable to use 

 any of these names for the Prince's Island form. 



There is one other name in the synonymy of Corytliornis 

 (jalerita of the Catalogue. This is Alcedo nais of Kaup 

 (Fam. Eisv. p. 13) which, however, is a nomen nudum, 

 though the type (which is preserved in the Brit. Mus. 

 Collection) is said to come from Gaboon. The first descrip- 

 tion is that of Hartlaub (Syst. Orn. Westafr. p. 37, 1857),
