98 ON CARPÜCOCCYX RADIATUS AND C. VIRIDIS. 



himself during his explorations in Western Sumatra (1833 — 

 36), although there is one specimen in the Leyden Mu- 

 seum labelled » Sumatra, voyage Salomon Muller." Pro- 

 fessor Schlegel in his Catalogue of the Ouculi (Mus. Pays- 

 Bas , 1864, p. 60), apparently misled by the duller colours, 

 enumerates this specimen as the »fem. adulte" of the bright 

 coloured Bornean-specimen , which latter he labels » male 

 adulte." The specific identity of the large Ground-Cuckoos 

 of Borneo and Sumatra was thus confirmed , although the 

 measurements given by Schlegel show such unusual difie- 

 rences in size that one might feel inclined to base upon 

 specific value. But Schlegel does not say that there are 

 also conspicuous differences in coloration , and it was not 

 before many years afterwards that Count Salvadori, who 

 got three specimens collected by Odoardo Beccari on Mount 

 Singalaug, west-coast of Sumatra, pointed out the specific 

 differences and, although hesitatingly, proposed a new 

 name (C. viridis) for the Sumatran bird. And this is in- 

 deed an excellent species, as will be seen by the following 

 characters taken from specimens in the Leyden Museum , 

 which possesses an interesting material on these birds , 

 still very rare in collections. In the British Museum , for 

 example, C. viridis is wanting.
