566 Recently published Ornithological Works. 



Since our last notice of the ' Biologia Centrali-Americana ' 

 (above, p, 451), another portion of the "^ Aves " of this great 

 work has been issued. The discussion of the Central- American 

 Trochilidse, of which no less than 118 species are now recog- 

 nized, is commenced, and the genera Heliothrix, Hemistephania, 

 Glaucis, lache, Phceoptila, Chlorostilbon, Thalurania, Micro- 

 chera, Callipharus, Eupherusa, Elvira, Hypuroptila, and 

 Lampornis are treated of. The arrangement followed is 

 quite a new one — that of Mr. Salvin^s new catalogue (Cat. 

 B. Brit. Mus. vol. xvi.), in which the serration of the bill is 

 used as a character to divide the Trochilidse into three sections. 

 The genera first taken belong to the first section, " Trochili 

 serrirostres.''' 



The following species are figured in this part : — Oreopyra 

 calolcema, Delattria hemileuca, Hemistephania veraguensis, 

 and Chalybura melanorrhoa. 



105. Hutton on the Muas, 



[On the Classification of the Moas. By Capt. F. W. Hutton, F.ll.G.S. 

 Abstract of paper read to the Canterbury Pliilosophical Institute ou 

 October 1st, 1891.] 



This is an abstract of what appears to be an important 

 memoir on the Dinornithidae. The family is divided by Capt. 

 Hutton into seven genera, to which 26 species are referred. 

 The generic characters are based '' chiefly on the skulls/^ 

 but also partly on " the sternum, the pelvis, and the robust- 

 ness of the leg-bones .^^ The species are " distinguished 

 almost entirely by size.^' The genera recognized are Dinornis, 

 (with two subgenera Dinornis and Tylopteryx), Palapteryx, 

 Anomaloptery X , Cela, Mesopteryx, Syornis, and Euryapteryx. 

 Dinornis excelsus, D. validus, D. firmus, D. potens, D. torosus, 

 Palapteryx plenus, Anomalopteryx antiquus, Euryapteryx 

 ponderosus, and E. pygmceus are characterized as new species. 

 It seems to us that it will be difficult to reconcile Capt. 

 Hutton's arrangement with that of the same group lately 

 given by Mr. Lydekker in his Catalogue of Fossil Birds [of. 

 Ibis, 1891, p. 456).
