There is one point on which we would be critical, viz., 

 the assumed intimacy of rehitionship between the Dinor- 

 uithidae and ^Epyornithidae. The researches of Biirckhardt 

 into the architecture of their skeletons would seem to suggest 

 for the latter a much more distinct origin than Avould our 

 author, and that the points of resemblance between them 

 may perhaps be due to convergence. We await, however, a 

 fuil knowledge of their palatal anatomy. 



As a new discovery there is announced in the skull of 

 the nestling Casuarius a separate ossification for the central 

 portion of the " casque,^' tlie homology of which has yet to 

 be determined. 



For the heart, there is recorded the fact that the moderator 

 band Mould appear to be very inconstant, since it was found 

 but once in the examination of five specimens ; and the author 

 corrects an obvious error of Forbes concerning the relation- 

 ships of the bursa Fabricii. 



This part of the memoir, illustrated by four admirable 

 plates and nine text-figures by Gronwald, is no less thorough, 

 as a whole, than in its classifieatory portion it is novel. 



The monograph in its entirety is one than which none 

 could have been better conceived or desired to fill the place 

 it occupies ; it is in all respects masterly in its details, 

 revolutionary in its salient points of originality, and will 

 remain a standard work in the ornithological literature of 

 the future.— G. B. H. 



81. Salvadori on Birds from Matto Grosso and Paraguay.

The birds of the great Bj'azilian Province of Matto Grosso 

 are pretty well known to us from the researches of Natterer 

 and the large collections of H. H. Smith (c/. Ibis, 1892, 

 p. 165, et 1894, p. 122). Nevertheless Dr. Borelli has 

 managed to add to the Avifauna a fine new Parrot [Pyrrhura 

 hypoxantha), already figured in this Journal (Ibis, 1900j 

 pi. xiv. p. 671). The 250 specimens collected by Dr. Borelli 

 at or near Corumba on the Bolivian frontier are referred
