group as T. doliatus; Myiodrjnastes sujjerciliosus, from Costa 

 llica, allied to M. chrysocephalus, Tschudi, and no doubt the 

 Hypermitres chrysocephalus ^ from the same country, of Dr. 

 Cabanis (J. f. 0. 1861^ p. 246), who then noticed the dif- 

 ference between the Costa-Rican and Peruvian examples ; 

 Aglceactis olivaceocauda, from Eastern Peru, which Mr. Salvin 

 assures us, from a comparison of the types, is identical with 

 A. caumatonota, Gould ; Heliomaster spectabilis, from Costa 

 Rica, which the same gentleman informs us is the female 

 of a species of Eugenes and possibly of (though the bill is 

 decidedly longer) E. fuJgens, a bird however which has not 

 yet been known to occur in that country ; Passerculus guttatus, 

 from Lower California ; Zonotrichia melanotis, Coturniculus mexi- 

 canus, Hadrostomus alhiventris, and Ortyx graysoni, all from 

 Western Mexico, of which the first is possibly the same as 

 Heemophila humeralis, Cabanis, the second probably identical 

 with Peucaa botteri, Sclater, while the third is one of the many 

 forms of Hadrostomus aglaice, Lafr., and, like H. affinis, Elliot, 

 perhaps hardly to be considered distinct, the fourth is allied to 

 O. pectoralis. The remaining species noticed in this paper are 

 named by Prof. Baird, and are: — Saltator plumbiceps, from ]\la- 

 zatlan ; Pheucticus tibialis, from Costa Rica; Spermophila atriceps, 

 from Mazatlan, allied to S. torqueola; Pyrgisoma xantiisi, from 

 Western Mexico, the description of which, Mr. Salvin tells us, 

 fits very well a specimen recently sent by M. Boucard, but 

 apparently identical with Melozone rubricata, Cab. (Mus. Hein. 

 i. p. 140, & J. f, 0. 1866, p. 234), if not the true Pyrgisoma 

 keneri, Bp. ; and, finally, Dendrornis mentalis, from Western 

 Mexico, allied to D. eburneirostris. 



Mr. Lawrence^s second paper contains descriptions of three 

 Humming-birds, all from Costa Rica: — Doricha bryantce, allied 

 to D. evelynce and D. elizce; Oreopyra venusta, which Mr. Salvin, 

 after seeing the type lent to Mr. Gould by Mr. Lawrence, 

 assures us is identical with 0. calolcema ; and 0. cinereicauda, 

 allied to 0. leucaspis, but having a grey instead of a steel-blue 



tail. 



Mr. Cassin's ' Third Study of the Icteridce ' has given rise
