Recently published Ornithological Works. 373 



now writes of the specimens obtained at various localities on 

 the Ucayali and Huallaga. After recording some interesting 

 notes by Garlepp upon the Toucans and Parrots of these 

 districts, the author proceeds to a systematic account of the 

 species represented in the collection. These are altogether 

 142 in number, concerning which many excellent critical 

 remarks are given. Cassicus pachyrhynchus is characterized 

 as a new species allied to C. hcemorrhous. Ornithion pusil- 

 lum olivaceum and Momotus brasiliensis ignobilis are two new 

 subspecies. Coloured figures are given (plate iii.) of two 

 rare Parrots, Ara couloni and Conurus roseifrons. Of the 

 latter, ten specimens were obtained by Herr Garlepp near 

 Tarapoto, and subsequently 31 more at Shanusi near Yuri- 

 maguas. 



63. Fiirbringer on Stringops and lynx. 



[Einige Bemerkungen iiber die Stellung von Stringops nnd den even- 

 tuellen Herd der Entstebung der Papageien, sowie iiber den systema- 

 tischen Platz von Jynx. Von Max Fiirbringer. J. f. 0. 1889, p. 236.] 



Herr Marshall, in his ' Zoologische Vortrage/ has main- 

 tained that Stringops should be considered rather as a modern 

 degraded form than as the oldest and least developed mem- 

 ber of the Psittacine group. Dr. Fiirbringer now gives good 

 reasons why the latter view, which he has adopted in his 

 " Untersuchungen," should be upheld. He likewise writes on 

 the question of the local origin of the Psittaci, which some have 

 maintained must have been in the Oriental, and others in the 

 Australian Region, and shows that we have not yet materials 

 for properly discussing this difficult subject. As regards lynx, 

 which he has treated as the lowest and least-specialized type of 

 thePicidse,Dr. Fiirbringer also explains his views on this point, 

 and shows that they are not materially different from those 

 of Herr Marshall; only the latter writer is inclined to regard 

 lynx as a more specialized development of the Picidse, while 

 Dr. Fiirbringer thinks that it should rather be looked upon 

 as a more primitive form of that group.
