[Notes on the Structure of Pedionomus torquatus, with regard to its 

 Systematic Position, By Hans (iadow, Ph.D., M.A. Records Australian 

 Mus. i. p. 205.J 



Dr. Gadow describes at some length the structure of 

 Pedionomus— s.n obscure Australian form, generally supposed 

 to belong to the Turnicidaj— from two specimens placed at 

 his disposal by the Trustees of the Australian Mu»eum, 

 Sydney. The conclusion arrived at is that Pedionomus must 

 be referred to tlie Turtiiccs, '' as their lowest, most Rallo- 

 Galline member." The sternum is " decidedly like that of 

 the Turnices, and differs in every essential point from that of 

 the Ilasores.'' In the pelvis also Pedionomus resembles 

 Turnix, and it is schizorhinal, like Turnix, whereas the 

 Galling arc holorhinal. The fifth cubital remex is absent. 

 The oil-gland is large and tufted.

The authors of the '' Birds " of the ' Biologia Centrali- " 

 Americana ' have made another important step forward in 

 the progress of this great work. In the recently issued 

 numbers appertaining to this branch of their subject they 

 take up the Formicariidse, and give us a full account of 52 

 species of this extensive family that occur in Central America. 

 Of the family Pteroptochidae, which concludes the long array 

 of Passeres, but one species — Scytalopus aryentifrons, a recent 

 discovery on the volcano of Irazu in Costa Rica — comes 

 within the limits of the work. Zeledunia coronata, another 

 newly described Cost-Rican form, is placed at the end of the 

 Passeres as a " genus incertcs sedis," until its anatomy and 

 osteology are known. 



As regards the Formicariidaj, Messrs. Godman and Salvin 

 follow pretty nearly the sequence of genera in this family
