Black Cockatoos, with the six subspecies of Probosciger 

 aterrimus, one of which (oorti) is uew. Woodcuts of bills 

 are given to justify the separation of Zanda and Harrisornis 

 from Cahjj)torhynchiis. The confused synonymy of C. banksii 

 is debated, and mistakes due to confounding the males, 

 females, and immature explained. Of five subspecies 

 recognised, samueli is new. Under Harrisoryiis , luthand 

 is preferred to viridis of Vicillot, and the subspecies habna- 

 turimis is dropped. Similarly, termirostris is given up 

 under Zanda bandinii; but xanthonotus and ivhitei are 

 retained under the species funerea, which is now definitely 

 assigned to Zanda. 



A new genus, Callocorydon, takes the place of Callo- 

 cephalon iov the Gangang, which stands as fimbriatus (Gm.), 

 with a new subspecies superior, tasmanicus being, moreover, 

 rejected. 



We now reach the White Cockatoo, of which the distri- 

 bution is discussed at length, and seven subspecies allowed, 

 interjecta being new. The extra-limital forms are also 

 brought under consideration, and from four to six sub- 

 species sustained, including a new one, ariiensis. 



As side issues Mr. Mathews cites and rejects names given 

 by Bourgeot St. Hilaire, while he proposes Eucucatua for 

 Kahator, if the latter is not approved. 



Finally, he retains Lophochroa Bp. for the species lead- 

 beateri, and Dncorpsius Bp. for sanguineus ; to the former 

 he allots four subspecies, superfiua being new, to the latter 

 five, weslralensis and normantoni being also additional. 



Peters on a new Swift.

 New Engl. Zool. Club, vi. 1916, pp. 37-38.] 



Mr. Peters describes Streptoprocne zonarius melanotvs 

 subsp. nov., allied to but distinct from the Cuban and 

 Jamaican forms. It was collected by the describer himself 

 in Santo Domingo, and is now in the Museum of Com- 

 parative Zoology at Cambridge, Mass.
