07. Amizilis ellioti (Berl.) replaces A. verticalis anct. 



Both Dr. llartert * and Mr. Ridgway t applied the name Trochiliis verticalis 

 Lichteiisteiii J to a species with (immaculate) white under tail-coverts found 

 in the western and central states of Mexico (Sonora, Sinaloa, Jalisco, 

 Michoaciin, etc.). In Eastern Mexico (states of Vera Cruz, Oaxaca, and Chiapas) 

 occurs the nearly allied ^1. c;/anocephala ci/anoce/ihala (Less.), chiefly characterised 

 by having the under tail-coverts olive-grey, faintly glossed with bronze and 

 margined with white. 



Tro(-liilas rcrticali.'i was founded ujwu sjieciraens obtained by the Prussian 

 travellers Deppe and Schiede in the late twenties of last century. Thanks to the 

 courtesy of Drs. Reichenow and Lorenz, 1 have been enabled to examine three 

 examples, belonging to tlie Berlin and Vienna Museums respectively, all marked 

 by Lichtcnsteiii liimscll' as " Trochibm rcrticnUx.'^ They were collected by Deppe 

 at Perote, a place situated between Fnebla and Jalapa, in the state of Vera Croz, 

 Eastern Mexico. These skins are unquestionably identical with the bird known as 

 A. ci/anocupliala, having the sides of the neck metallic green, and the nnder 

 tail-coverts pale brownish olive, edged with wliite, and agree in every respect with 

 a series from Jalapa and Oaxaca. 



T. verticalis is, therefure, to be relegated to the synonymy of Amizilis 

 c. cyanocephala, while the West Mexican species has to bear the name Amizilis 

 ellioti (Berlepsch).

0. euleri is certainly the rarest among South American Cuckoos. The type 

 was obtained by Enler at Cantagallo, in the province of Rio de Janeiro, and is 

 preserved in the Berlin Museum. Mr. Stone recorded a specimen from the interior 

 of British Guiana that had been forwarded to the Academy of Natural Sciences of 

 Philadelphia. In the British Museum there is a second example from the same 

 country, taken by H. Whitely at Aunai on June 24, 1889. H. H. Smith secured a 

 single male near Chapada, Mattogrosso, S.W. Brazil, on October 28, 1883, which is
