It will be seen that the adult C. nifidorsa and C. dillwynni are easily dis- 

 tinguishable, but that the young of the two species are very similar to each other 

 and easily confounded. Moulting specimens, however, will mostly show where thev 

 belong, as those of C. mfidorsa become redder on the wings and scapulars, those of 

 C. diUwynni blacker. Tiie blackish spot on the forehead seems also to be peculiar 

 to the latter, perhaps also the presence of black in the tail. Sometimes the locality 

 gives a good clue. 



The "intermediates" between C. dillwynni and euerylhra of Hharpe are young 

 dillwynni, while his " intermediates " between C. euerythra and C. tridactyla are 

 apparently young mfidorsa, though two or three seem to belong to dilhoymii. 



The young birds of both C. dillwynni and C. mfidorsa are clearly those that 

 have led to confusion, but I believe that my e.xplanation, which, as already said, is 

 based on large material and I have no doubt is quite correct, will make the Ceyx 

 " problem " clear.

* If specific names are treated as adjectives and brought into harmony with the gender ot the 

 generic name, then Ilalei/on must be treated as a feminine, as has generally been done, though Sharpe 

 treats it as a masculine. Not because nalcyon is one ot the forms of the name of Alcyoiie, the wife of 

 Ceyx, but because the bird called ^ iXKi/ii/ by the ancient Greeks was feminine, and because tjwainson 

 treated it so, it must now be considered to be of feminine gender.
