the genitive, sayi or sail, or in adjectival form, saynna or saiana it must in the latter 

 case be feminine to agree with sayiornis. The above emendation of both generic and 

 specific names is respectfully submitted. (See Coues, Bull. Nutt. Club, v, 1880, p. 99.) 



378. S. nig'-rl-cans. Present participle of nigrico, I am blackish; niger, black. 



379. S. fus'-ca. Lat./uscus, dark, dusky, swarthy. See Pipilo, No. 306. 



380. Con^td-pus bfir-g-a'-lis. Gr. n6vTos, in some sense unknown to us, and TTOUV, foot. Lat. 



borealis, northern ; boreas, the northwind. " Pewee/' like " pewit/' is an onomatopoeon. 



N. B. Many words ending in -opus, from the Gr. TTOVS and a connecting vowel o, are 

 habitually accented on the lengthened penult, and the last syllable is made short. But 

 as -pus here stands for Gr. irovs, and the connecting vowel is invariably short, we should 

 throw the accent back to the antepenult, and dwell on the last syllable. Thus, not 

 Conto'-pus, Hcemato'-pus, Phalaro'-pus, but Cont'6-pus, HcEma'tG-pus, Phalar'0-pus. 



381. C. per'-tl-nax. Lat. pertinax, pertinacious, holding fast on to ; from per and tenax, tenacious, 



from teneo, I hold ; this species closely resembling C. borealis. 



382. C. vir'-ens. See Dendrceca virens, No. 112. 



383. C. v. rlch'-ard-sfin-i. To Dr. John Richardson, an author of the Fauna Boreali- 



Americana, &c. 



384. Em-pld-o'-nax a-cad'-I-cus. Gr. fairls, genitive tfurtHos, a small kind of insect, gnat; and 



2>va. or #va|, king. Acadicus, Latinized adjective for Acadian ; from Acadia or Acadie. 



N. B. This species has never been found, and probably does not occur, in the region 

 formerly called Acadia; the name is therefore geographically false. The name "Aca- 

 dian Flycatcher," whence Muscicapa acadica Gm., no doubt actually refers to Traill's or 

 the Least Flycatcher, the proper name of the present species being probably Empidonax 

 subviridis (Bartr.) Coues. Lat. subviridis, somewhat green, greenish. 



385. E. trail'-li. To Thomas Stewart Traill, a Scottish naturalist. He was professor of medi- 



cal jurisprudence in the University of Edinburgh, and editor of one of the later editions 

 of the " Encyclopaedia Britannica." 



386. E. t. pu-sil'-lus. See Sitta, No. 60.
