NEW BIRDS FROM KAMTSCHATKA. 97 NOTE ON THE GENERIC NAME CALODROMAS. BY ROBERT RIDGWAY. (Read February 23, 1884.) In 1873 (" Nomenclator Avium Neotropicalium," p. 156), Messrs. Sclater and Salvin proposed the name Calodromas for Eu-dromia elegans, Lafr. & D'Orb. This name, however, is preoccu pied, having been given to a genus of Coleoptera by Goudot, in 1832 (Rev. et Mag. de Zool.) I therefore propose as a substitute Calopezus (xaAo? =.pulchcr, xeZ6$ =. ptdcstris.} DIAGNOSES OF NEW SPECIES OF BIRDS FROM KAMT-SCHATKA AND THE COMMANDER ISLANDS. BY LEONHARD STEJNEGER.
