The collection was made during the years 1SS5 and 18S6 by Dr. II II 

 Rusby, "the well-known botanist," who "made a journey diagonally acro.-s 

 northern Bolivia, starting at Arica in Chili and proceeding thence north- 

 eastward to the head waters of the Rio Madeira, and thence down this river 

 to the northern border of Bolivia." The number of specimens was about 

 400, representing 267 species, about 125 of which are added to the list of 

 previously known Bolivian birds, while no less than 13 are apparently 

 new to science. A complete list of the species is given, with critical anno- 

 tations when they seem called for, while Dr. Rusby's very interesting 

 field-notes are given in brackets and are followed by the initial 'R\ 



The new species and subspecies described are the following: — Em- 

 pidonax boliviaxus, Cliiroxiphia pareola boliviano., Unicornis stria/a, 

 Leptasthemira fnscescens, Leptasthcnura fuliginiceps boliviano., Synallaxis 

 griseiventris, Anabazenops immacnlatus, Picolaptes ob/ect/es,* A/yrmo- 

 chanes (gen. nov.) //vpo/eucus, Conopophaga rnsbyi, P/ilogopsis notata, 

 and Scvtalopus bolivianus. 



The annotated species are the following : Atticora cyanolciica montana 

 Baird, the subspecific characters originally ascribed to which are distinctly 

 seen in the Bolivian bird; Ccereba cienilea (Linn.), Bolivian specimens 

 of which "have the bill very short and slender, shorter and smaller even 

 than Bogota specimens .... labelled Ccereba ccerulea microrkyncha by 

 Berlepsch"; Eupkonia laniirostris Lafr. & D'Orb., which differs "from 

 Bogota specimens {E. crasstrostris Scl.) in having the bill much smaller, 

 the yellow of the cap much deeper (orange yellow)," and in other partic- 

 ulars ; Paroaria gularis cervicalis (Scl.), P. cervicalis Scl. being '•doubt- 

 less only a local form of P. gularis" to which Mr. Allen thinks /'. copi- 

 tata (D'Orb. & Lafr.) also probably referable in the same manner; Pac/iy- 

 rhamphus niger Spix, a specimen of which "is much blacker below, with 

 less white on the scapulars, wings, and tail than in Brazilian and Cayenne 

 birds"; Lathria plumbea (Licht.), if not L. cinerea (Vieill.). which Mr. 

 Allen regards as doubtfully separable; Cinclodes rivularis (Cab.), the 

 complicated synonymy of which is disentangled ; Formicarius ana I is 

 (Lafr. & D'Orb.), a specimen of which agrees essentially with the type; 

 Pteroptochos albifrons Landb., which Mr. Allen regards, and we believe 

 correctly, as a "'good species,' or at least as not referable to 6'. magel- 

 f aniens" '; Hvlactes casta ueus Phil. & Landb., the young of which i-> 

 described; Trogon collaris Vieill., a male of which is described; Gal- 

 balcyrhynckus leucotis Des Murs, the single specimen having the bill 

 "about 7 mm. longer than the maximum given by Sclater in his mono- 

 graph of the family." — R.R. 



Allen on the Genus Cyclorhis. — Three times within the space of five 

 years had this genus been 'monographed': by Mans Gadow in iSS^,! by 



* This, however, from an unknown locality, the type belonging to the Lafresnaye 

 collection in the Museum cf the Boston Society of Natural History.
