Bangs Birds from Costa Rica and Chiriqui. 



The two subspecies of Pyrrhura lioffmanni are easily recognized by the 

 Costa Rican true hoffmanni being without red tips and shafts to the feathers 

 of nape and crown (one skin only out of a large number examined show 

 ing any) and the Chiriqui form, gaudens, having always, when adult, such 

 red markings, often very conspicuously developed. 



Eumomota superciliaris australis subsp. nov. 



Type from Bebedero, Costa Rica, c? adult, No. 16,499, coll. of E. A. and 

 O. Bangs. Collected February 11, 1890, by C. F. Underwood. 



Characters. Similar to true E. superciliaris, but paler in color throughout, 

 blue color of wings and tail much paler, more greenish blue ; superciliaries 

 chiefly whitish or very pale blue; cinnamon-rufous of middle of back and 

 belly paler, particularly so on belly; and wings quite different in charac 

 ter, the primaries much shorter in proportion to secondaries, so that the 

 secondaries reach nearly to the wing tip ; black tips of tertials and second 

 aries much shorter. 



MEASUREMENTS. 



The Underwood collection contained but two skins of this bird, which is 

 I believe rare and local in Costa Rica, both from Bebedero, the type, 

 an adult male taken February 1 1 , 1890, and an adult female, September 

 11, 1893. These two are alike in all important points, and differ very 

 much from any northern specimen I have examined a score or more in 

 the very peculiar wing with the secondaries and tertials reaching almost to 

 the wing tip, instead of falling far back of it. The short black ends of 

 the tertials and secondaries and the generally paler and duller coloring 

 of the southern bird are also striking characters, and if other Costa Rican 

 examples prove like my two I believe this southern extreme will be found 

 to be more than subspecifically different from the northern true E. super 

 ciliaris (Sandbach). 



Crypticus a piaster Lesson, Rev. Zool. 1842, p. 174, was described from 

 " San Carlos Americse Centralis, Oceani Pacifici." As every Central Amer 

 ican State except British Honduras has a town in it called San Carlos, I 

 am at a loss to tell just whence Lesson's type came. There is nothing in 

 the description to indicate that the bird differed in any way from true 

 Eumomota superciliaris, and I am forced to regard Lesson's name as a syno 

 nym of the northern form. 



Saucerottea cyanura impatiens subsp. nov. 



Type (and only specimen) from San Pedro, Costa Rica, fully adult (J 1 , 

 No. 16,684, coll. of E. A. and O. Bangs. Collected October, 1904, by C. F. 

 Underwood.
