370. T. ver-tl-caMls. Lat. verticalis, vertical, t. e., relating to the vertex, top or crown of the 



head, which has a flame-colored patch. The etymological meaning of vertex is vortex, the 

 turning or whirling thing, from verto, I turn. 



371. T. vo-cl'-fer-ans. Lat. present participle vociferans, vociferating, vociferous, from vocifero ; 



vox, genitive vocis, voice, andyero, I bear. 



373. T. mgl-an-chSF-I-cus. Gr. /teAayxoAimfc, melancholy, from /ieXos, feminine /ieAotj/a, black, 

 and x^os, gall, bile ; Lat. melancholicus, atrabilious. The ancients had some notions on 

 this subject which make the term not wholly inapplicable to a bird of splenetic, irri- 

 table disposition, as all of this genus are. To Lt. D. N. Couch, U. S. A., who collected 

 extensively in Matamoras and Texas. 



373. Myl-ar'-chus cri-m'-tus [not " crinnytus," as usually heard]. Gr. //u?a, a fly, and apxos, 



a ruler, leader, chief, from &px<, I am first, lead, rule, or apx"fi, the beginning. This 

 theme is seen in our prefix arch-, as arch-bishop, &c. Lat. crinitus, haired, i. e., crested, 

 from crinis, hair of the head. See Myiodioctes, No. 146. 



374. M. 6-ryth-r6-cer'-cus. Gr. tpvep6s, reddish, and MPKOS, tail. 



Not in the Check List, orig. ed. Since discovered in Texas by G. B. Sennett. The 

 proper name of the species is much in question. The bird is the M. crinitus erythrocercus 

 of Coues, Bull. U. S. Geol. Surv. Terr., iv, no. 2, p. 32, and v, no. 3, p. 402 ; the M. eryth- 

 rocercus var. cooperi of Ridgway, Pr. Nat. Mus., i, p. 138; and the M. mexicanus of Ridg., 

 Pr. Nat. Mus., ii, p. 14. 



375. M. cln-gr-es'-cens. Lat. present participle of an inceptive verb cineresco, I grow ashy ; 



in the sense of being somewhat ashy ; cinereus, ashy, from cinis, ash. N. B. The 

 name has always been written cinerascens, for which we find no authority; while there 

 is actually a verb cineresco : we therefore emend as above. 



376. M. law-rgn'-cl-i. To George Newbold Lawrence, of New York. 



377. Say-i-or'-nls say'-i. " Sayornis " is a violent combination of the name of Mr. Thomas 



Say, of Philadelphia, with the Greek word for bird, &pvis. It may be somewhat improved 

 as above, when the combination of vowels becomes no more unusual than is seen in 

 myw-dioctes, myia-rchus, &c. In equally loose style, Bonaparte made the specific name 

 sayus, a direct Latinization of the same person's name; but it must either be put in
