Herr Hartert's contribution to the present volume contains 

 an account of four families of the suborder " Coracise/' ac- 

 cording to Dr. Giinther^s classification, namely the Cypselidae, 

 Capriraulgidaj, Steatornithidse, and Podargidge. Herr Hartert 

 has had a very tough job to master as regards the Caprimul- 

 gidse, and those who have paid attention to this embarrassing 

 group will, we are sure, much appreciate the way in which 

 he has surmounted his difficulties. According to Herr Har- 

 tert^s arrangement the Caprimulgidse contain 86 species, 

 while the Cypselidse have 78 species, the Podargidse 24, and 

 the Steatornithidse only 1, but a good many subspecies are 

 likewise recognized. 



The 16th volume of the Catalogue, therefore, gives us 

 altogether au account of 687 species of birds, represented 

 in the National Collection by no less than 12,286 specimens. 



The following new genera are established in this volume : — 

 Neolesbia, Salvin, type Cyanolesbia nehrkorni, p. 145 ; 

 Aeronautes, Hartert, type Panyptila melanoleuca, p. 459 ; 

 and Claudia, Hartert, type Cypselus squamatus, p. 469. 



The only actually new species now named for the first 

 time seem to be Caprimulgus yucatanicus and JEgotheles 

 salvadorii; but there are also two new subspecies proposed, 

 namely Collocalia francica merguiensis and Chatura cinerei- 

 ventris guianensis. 



The following species are figured in this volume : — Upupa 

 somalensis ; Irrisor bollii ; I. jacksoni ; Scoptelus castanei- 

 ceps ; Panychlora micans ; Chlorostilbon peruanus ; Heli- 

 angelus laticlavius ; H. violicoUis ; He/ioirypha spcciosa ; H. 

 barrali ; Agyrtria caruleiceps ; Amazilia sumichrasti ; lolcpma 

 luminosa ; Phaolama cervinigularis ; Eriocnemis dyselivs ;
