107. H. ce-la'-ta. Lat. celatus, concealed, from celo ; the orange color of the crown being hidden. 



108. H. c. lu-tes'-cens. Lat. inceptive verb lutesco, present participle lutescens, from luteus, 



yellow ; from lutum, an herb used in dyeing yellow. There is actually no such verb as 

 Jutesco, the describer of the species having apparently mistaken lutesco, I grow muddy, 

 become miry, for a supposed lutesco, I grow yellow, by some confounding of luteus, 

 muddy, loamy (hence possibly clay-colored or yellowish) with luteus, golden-yellow. The 

 bright yellowness of the bird in comparison with H. celata being its prime characteristic, 

 the propriety of assuming the derivation to be from lutum, and hence writing lutescens, 

 from a supposed lutesco, is obvious. 



A form lately distinguished by Ridgway, Am. Journ. Sci., 3d ser., iv, 1872, p. 457. 



109. H. pSr-g-gri'-na. Lat. peregrinus, wandering, alien, exotic, that comes from foreign parts; 



from per, through, and ager, a field or land ; literally, " across country." 



110. Peu-cS'-dra-mus 81-I-va'-c6-us. Gr. irevitr), a pine-tree, and Spa/j.f7v, 2d aorist infinitive, 



from rpexv, I run - The allusion is to the pine creeping habits of the bird. N. B. Many 

 genera are compounded from the same root, and spelled either -dranms or -dromus. Either 

 is correct. Lat. olivaceus, pertaining to the olive ; in this case, in color, olivaceous. 

 Not in the orig. ed. Since discovered in Arizona by H. W. Henshaw. 



111. Den-droe'-ca aes-ti'-va [dayndrwaykah aysteevah]. Gr. Mrfpov, a tree, and ot'irc'u, I 



inhabit ; dittos, a habitation. The word was originally compounded Dendroica by G. R. 

 Gray: later emended as above. The full form would be Dendraecetes, like. Pooecetes, 

 Nephcecetes (OIK^T^S, an inhabitant). Lat. cestiva, adjective from cestas, the summer 

 season ; cestus, heat, ardor (Gr. aWta, I burn). Notice the long accented penult. 



112. D. vir'-ens [pronounced virraynce]. Lat. virens, participle present of vireo, I grow green. 



113. D. oc-cl-den-ta'-lls. Lat. occidentalis, occidental, western; that is, in the place where the 



sun sets ; from occido, I fall down.
