Recently published Ornithological Works. 727 



of the Museum of Natural History would have been the 

 proper place for the second and third parts of their memoir 

 as well as for the first. 



In the first part the families Conopophagidse and " Hylae- 

 tida? " are discussed, "Hylactidse" being a new name for 

 the family called " Pteroptochidse " in the 'Catalogue of 

 Birds ' of the British Museum, which the authors profess to 

 follow. But llijlactes, they allege, is an older name than 

 Pteroplochus, and it is the practice to form a family-name from 

 the oldest genus. The names of the species of Conopophagida? 

 and Hylactidse are taken in systematic order, nearly in 

 accordance with the arrangement in the ' Catalogue of 

 Birds/ and an exact list of the specimens at Paris is 

 given, "with localities, dates, and critical remarks. 



The second part of this memoir relates to the Dendroco- 

 laptidae, of which 121 species are discussed in the same 

 fashion. Two new forms are introduced — Geositta pay tee, 

 from N.W. Peru, and Philydor columbianus riveti, from 

 Ecuador. We may remark that several species which 

 we should consider valid are here reduced to the rank of 

 subspecies. 



The third part is devoted to the Formicariidse, and con- 

 tains notes on 57 species and subspecies, of which three are 

 described as new — Myrmelastes cryptoleucus from Pebas 

 (Amazonia), Formicivora devillei from N.E. Peru, and 

 Chamceza brevicauda venezuelana from Venezuela. 



We hope that the authors will continue their studies, and 

 treat the Tyrannidse and other obscure groups in a similar 

 manner.
