appearance and unusual habits, but ''Bronze Cuckoos'-' 

 occupy the bulk o£ this part of the work. 



In regard to Cacomant'is pyrrophanus we are told that the 

 tN'pe-locality is still uncertain, and that insperatus of Gould, 

 tymbonomiis of Kamsay and brishanensis of Digoles, are mere 

 synonyms. On the other hand, dumetorum, variolosus and 

 lineatus are allowed subspecific instead of specific rank, as 

 representing north-western, south-western, and Queensland 

 forms. To these is added a new subspecies vidgeni, from 

 Cape York, while the New Guinea forms may have to be 

 separated. 



Mr. Matliews' new genus Vidgenia, based chiefly on 

 peculiarities in the immature bird, contains only the rare 

 Chestnut-breasted Cuckoo, with no certain subspecies and 

 an obscure life-history ; the young bird is to be figured 

 shortly. 



Another I'are Cuckoo is Owenavis osculans [Misocalius 

 auctt.), wrongly identified by Cabanis and Heine with 

 palUolatus of Latham. Here a subspecies, rogersi, may 

 possibly be allowed in the north-west. 



The author no longer presses for the adoption of Neo- 

 chalcites for Chalcites in the case of the Narrow-billed 

 Bronze Cuckoo, well known under the name basalts, while 

 he recognizes as subspecies mellori. ivyndham'i jind niodesta. 

 Many good notes on its habits are cited. 



Four species are allotted to Lamprococcyx, viz., luadcs, 

 plagosus, minutillus and russalus, thougii it is possible that 

 the first two are only subspecifically different, especially if 

 Mr. Mathews' suggestion that thej'^ are really sedentary in 

 New Zealand aud Australia respectively proves to hold 

 true. The relation between the remaining pair is still more 

 complicated : minutillus is synonymous with malayanus of 

 Shelley, while russatus is now found not to belong to the 

 basalis group, as the author formerly believed, and barnardi 

 is relegated to a subspecies. L. plagosus has the subspecies 

 carteri and tasmanicus. Tails of all these species (and of* 

 barnardi) are figured for comparison. 



The well-known Koel [Eudynamis orientalis) presents no
