genera, while some of the species of these two groups are most certainly 

 much more nearly' related to each other than they are to any of the inter- 

 posed groups. Our Robin group is allotted to Tiirdus, and forms the 

 only American species of the genus, except T. rufitorques of Mexico and 

 Central America. 



It seems like returning to the 'good old times ' to see such groups as the 

 Mimidae, Regulidae, Paridpe, Certhiid^e, etc., installed again as full-fledged 

 families. 



Partis is restricted to a group of Old World Titmice, the American spe- 

 cies hitherto referred to Parus being placed in Pxcile Kaup, except P. 

 gambeli, for which the new genus Paecilodes Bianchi (1902) is adopted. 



The recent additions to the list of described forms are given at their face 

 value, with, however, references to adverse opinions when any such have 

 been made public. In short, the care, thoroughness and fairness of Dr. 

 Sharpe's great work will long render it a most invaluable aid to every 

 systematic ornithologist. — ^J. A. A. 



Ridgway on New American Birds. — Mr. Ridgway, in prepaiing Part 

 III of his ' Birds of North and Middle America,' has found it desirable to 

 describe a number of new genera, species, and subspecies.' The new^ 

 genera comprise the following four genera of Swallows, as follows: 

 Alopochelidon, type, Hirundo fucata Temin. ; Orochelidon, tvpe, Petro- 

 ^helidon inurina Cass. ; D/'plochelidon, type, Hirundo melanoletica Wied ; 

 Lamprockclidon^ tjpc, Hirundo euchrysea Gosse. The new species and 

 subspecies, 29 in number, are mostly from Mexico and Central America, 

 but the following come within the scope of the A. O. U. Check-List: (i) 

 Budytes. Jlavtis alascensis. Western Alaska; (2) Vireo huttoni cognatus. 

 Cape district of Lower California ; (3) Vireo bellii arizonce, western 

 Texas and Arizona ; (4) Lanitis ludoxncianus tnearnst, San Clemente and 

 Santa Margarita Islands, L. Cal. ; (5) Bceolophus iuornaius res/rictus, 

 vicinity of San Francisco Bay, Cal.; (6) B. i. murinus, northern Lower 

 California ; (7) Psalfriparus minimus saturatus, Mount Vernon, Wash. ; 

 {S) CJiamcea fasciata rufula, central coast region of California ; (9) Mis.s- 

 issippi ^^alley and Great Plains region, north to Alberta. — J. A. A. 



Nelson on New Birds from Mexico. — The 13 new species and sub-
