Though in general appearance somewhat intermediate be- 

 tween Methriopterus and HarjJorhynchus , Mimodes, it is con- 

 sidered, is really " very much more nearly related to the genus 

 Minius.'' 



37. Ridgway on the Tree-creepers (Certhia) . 



[Critical Remarks on the Tree-creepers (Certhia) of Europe and North 

 America. By Robert Ridgway. Proc. U.S. Nat. Miis. 1882, p. 111.] 



After examining considerable materials^ Mr. Ridgway comes 

 to the conclusion that there are 7 races or subspecies of the 

 Tree-creeper (Certhia) susceptible of definition : (1) fami- 

 liaris of Scandinavia, (2) costa of Savoy, (3) britannica, 

 subsp. nova, of England, (4) rufa of Eastern U. S., (5) mon- 

 tana, subsp. nova, of Middle U. S., (6) occidentalis, subsp. 

 nova, of Western U. S., (7) mexicana of Mexico and Guate- 

 mala. These are all carefully defined, and measurements 

 are added. What do Messrs. Dresser and Seebohm say to 

 this new " British bird " ? 



38. Salvaduri on the Cassowaries. 



[Monografia del gen. Casuarius, Briss., per Tommaso Salvadori (con due 

 tavole colorite). Estr. dalle Memorie della Reale Accademia delle Scienze 

 di Torino, serie ii. torn, xxxiv.] 



A complete account of the present state of our knowledge 

 of the Cassowaries was much wanted ; it has been now sup- 

 plied to us in this excellent memoir. After a historical 

 introduction and bibliography, the 10 species of the genus 

 recognized as distinct are successively discussed. Of the first 

 section, with the helmet compressed, the species acknow- 

 ledged are C. tricarunculatus , C. bicarunculatus, C. galeatus, 

 C. australis, and C. beccarii. Of these the first, founded on 

 a single young living specimen, which has never reached 

 Europe, is considered to be doubtful. C. salvadorii of Ous- 

 talet and C. altijugus of Sclater are referred, not without 

 some doubt, to C. beccarii. 



Of the second section of the genus, with the casque flattened 

 behind, five species also are allowed — namely C. uniappen- 

 diculatus, C. occipitalis, C. papuanus, C. picticollis, and C.
