in the American Mnsenm of Natural Histoiy in New York. This is the specimen 

 referred to by Allen and Chapman. According to the latter author, the type of 

 C. lindeni, collected by Linden at Santarem, on the month of the Tapaj6z, and, 

 forming part of the Mnsenm of Comparative Zoology at Cambridge (Mass.), 

 belongs also to the same species.* To these are now to be added the two 

 examples given at the head of this article, making a total of seven records. 



The specimen of Natterer's (who, as in so many other cases, was the real 

 discoverer of the species) answers well to the original description. C. euleri is, in 

 fact, only a diminutive form of the North American 0. americanus (Linn.), but has 

 no rufous whatever on the wings, and nearly pure white (instead of buff) axillaries 

 and under wing-coverts. The colonr of the bill is exactly the same : maxilla 

 black, basal half of maxillary tomium and the mandible orange-yellow, extreme tip 

 of the latter blackish. The upper parts are pale greyish brown, glossed with bronze 

 (like C. americanus) ; the anterior portion of the pilenm, lores, and an obsolete 

 stripe above the eye cinereous; auricular region pale brown, darkening anteriorly; 

 wing-coverts pale bronze-brown, like the back ; remiges dusky, outer webs light 

 brown, with bronzy sheen ; three outer pairs of rectrices black, with long white 

 tips, the two succeeding ones light bronze-brown, passing into blackish terminally 

 and ending in a narrow white margin, the median pair wholly bronze-brown ; 

 under surface white, foreneck and sides of breast faintly washed with greyish ; 

 inner web of quills broadly edged with pale buflf at basal portion. 



The Surinam bird is rather larger, with longer bill, and the bufif quill-lining 

 is less conspicuous. These trifling variations are most probably individual. 



C. euleri, notwithstanding its rarity in collections, appears to be rather widely 

 distributed in Sonth America, ranging from the Gnianas to Southern Brazil (Sao 

 Panlo). Nothing is known about its life-history, but it is doubtless a resident and 

 not a migrant from some northern country.

Cuculus velox was described by Dr. Andreas Wagner, then Curator of the 

 Zoological Collections at Munich, from an example obtained by Karwinski some- 

 where near the city of Mexico (exact locality not stated). Shelley f jmt it down as a 

 synonym of (}.'■'■ mexicanus," = G. calif oniianus (Less.), but examination of the type 

 specimen proves this view to be erroneous. The type, an adult bird in rather worn 



• Dr. Allen says that the " strongly cinereous colour of the lower parts " is a con.spicuous feature 

 in V. tindrni. Tliis does not well agree with the specimens examined by me, in whicli the under surface 

 is nearly pure wliitc.
