Besides including these interesting novelties, Dr. Merrill’s paper, 
like Mr. Sennett’s, gives copious field notes of habits gathered in 
the course of the author's long experience with the subjects of 
his communication. The list of species reaches the large num- 
ber of 252; and yet we understand that none are included which 
did not come under Dr. Merrill’s personal observation. This is 
certainly a good showing, though doubtless no one knows better 
than the author himself that still further additions remain to be 
made to it. The large collections upon which the list is based 
were sent to the Smithsonian from time to time, and there care- 
fully examined by Mr. Ridgway, upon whose authority the 
identifications rest. The same s Samy eng has added much 
The evident care with which he has made his determinations 
causes us to regret the more our difference of opinion respecting 
the identification of the Mexican Myiarchus, which we had before 
Satisfied ourselves to be erythrocercus of Sclater and Salvin, and a 
geographical race of crinitus. It seems to us useless to attempt 
to do anything with so ieee a bird as cooperi of Kaup; and 
we must adhere to our previous decision. The hummers before 
announced as Amazilia pialane and Pyrrhophena riefferi are 
renamed respectively A. yucatanensis and A. fuscicaudata. The 
paper is further enriched by various odlogical notes contributed 
by Dr. Brewer, who appears to have examined the very large 
number of eggs collected by Dr. Merrill, and who has also given 
that slight sketch of the geographical ‘distribution of Podic ceps 
dominicus, to which we have already alluded. It is accompanied 
also by three of Mr. Ridgway’s plates, so excellent in details of 
external form, representing Parra gymnostoma, <Echmoptila albi- 
Jrons, Nyctidromus albicollis and several species of Caprimulgus. 
Under such circumstances, both of authorship and editorship, it 
is not surprising that the paper forms one of the most notable 
contributions ever made to Texan ornithology, being, as such, 
quite worthy to rank with those of Sennett and Henshaw ?— Æ. i
