We therefore find in Sharpe's Hand-List that the family 

 Cuculida is made to contain 45 genera of Cuckoos, and these 45 

 genera include no less than 161 species. This is a great many 

 different kinds of Cuckoos, and to me it is the most significant in- 

 dex extant, indicating how little, how very little, we yet know of 

 their morphology, and consequently how much guesswork there 

 must essentially be in our attempts to classify them. 



The writer is indebted to Mr. Lucas, of the U. S. National 

 Museum, for the loan of a skeleton of a Jacamar (sp. ?), a Diplop- 

 terus, and a specimen of Nyctiornis amictus from Borneo — one of 

 the Meropidce. All of these I have examined in the present con- 

 nection and compared them with skeletons of Ceryle alcyon and 

 Ceryle cabanisi. 



Unfortunately the skeleton of Diplopterus had been injured, but
