50. P. ru-fes'-cens. Lat. rufescens, present participle of the inceptive verb rufesco, to grow red ; 



be rufous. " Chickadee " is an obvious onomatopoeia, from the bird's note. 



51. P. r. neg-lec'-tiis. Lat. neglectus, neglected ; verbnegligo; equal to nee (won), not, and lectus, 



chosen, picked, taken ; lego, I gather in, select, &c. Neglect is a nearly exact opposite 

 of collect. 



52. P. cmc'-tus. Lat. cinctus, girdled; perfect participle of cingo, I surround, encompass, 



encircle. A cingulum is a little something that goes around as a girdle does, whence 

 surcingle, cinche. 



53. P-sal-trl-pa'-rfls mln'-I-miis [sound the initial p ; the a in parus is properly long ; some- 



times shortened in composition]. Lat. psaltria, Gr. \^d\rpia, one who plays on the lute; 

 from the verb psallo, tyd\\(a, to strike such an instrument ; English psaltery, &c. ; and 

 parus, a titmouse. See No. 44. Lat. minimus, least, superlative of parvus, small. 



54. P. plum'-be-Qs. Lat. plumbeus, plumbeous, lead-colored. 



55. P. mfcl-an-o'-tls. Gr. /j.4\as, genitive peXavos, black ; ols, genitive a>r6s, ear. 



Not in the orig. ed. of the Check List, and scarcely established as North American, 

 though given by Baird in 1858. Supposed to have been seen by Ridgway in Nevada, 

 August, 1868. See Rep. Surv. 40th Par., iv, 1877, p. 415. See Index, p. 137. 



56. Aur-I-pa'-riis [owriparusj fla'-vl-ceps. Lat. aureus, golden, from aurum, gold ; and parus, 



a titmouse. Lat. Jlavus, yellow, forflagvus, fromflagro, to glow; whence English defla- 

 grate, flagrant, &c. Ceps is a Lat. termination, from Gr. KfQaX-f), the head; compare 

 caput, cephalic, occiput, &c. A more strict method of compounding aure-us with parvs 

 would give aureiparus ; but it may be taken direct from aurum, making auriparus admis- 

 sible ; as we should say " gold-tit," like " bush-tit," " coal-tit." 



57. Sit'-ta ca-r6-lln-en'-sls. Gr. <rlrra, (rirrti ; Lat. sitta, a nut-hatch ; the word occurs in 



Aristotle. It is related to a-iTrdicri, ^/irraKos, Lat. sittace, psittacns, a parrot ; the implication 

 being some sharp sound made by the bird, as English pint ! There is a Greek verb 

 tyirrdfa, to make such a noise. Lat. carolinensis, see Mimus, No. 13. 



58. S. c. a-cu-ie-a'-ta. Lat. aculeatus, sharpened, dim. aculeus, sharp, acus, a needle ; from acer, 



sharp. Gr. &K(S, a point ; compare antav, a.K/j.-fi, &fcpos, &c., English acme, acropolis, acer- 

 bity, acrimony, and numberless words in many languages, from ^ak.
