nirt! in Enstom Massiichnsftts, tlu)ii;;li not unknown. A renmrkaMo exception to 

 this otherwise >,'enenil rule occinred in tlie sjpi'inj,' of iSTli. For several days, in 

 tlio latter part of May, they were foinul in irreat ahuntlanee in the vicinity of 

 IJoston. As tiie same nnusual occurrence of tiiis species in large nuniliei's was 

 noticed by Mr. Kunilien in .Southern Wisconsin, it is proltalile that ahaii;' the 4L'd 

 parallel something occurred to cause a deviation from their usual migrations. 

 The long ]iaiise of this species in its spring migrations, and its appearance in 

 large ninnliers, are not known to have occurred before. 



Mr. Salvin (ll)is, April, lf<7:') expresses the oi)inion that this Warbler, in its 

 Houthern migration, does not pause in its Hight from the Southern I'nited States to 

 stop in any of the West India Islands, nor in any point of Central America north 

 of Costa Iiica. It is by no means rare at Panama during the winter. We may 

 therefore infer that in both its southei-n and its northern migrations long flights 

 are made, at certain jieriods, over sections of country in which they do not appear 

 tit all, or where only a straggling few are ever seen, and that their abundance in 

 187- was exceptional and due to causes not understood. 



Dendroica nigrescens (1, 2.'")8). Obtained in EI Paso County, Colorado; 



AlKKN. 



Dendroica occidenteilis, D. townsendi, and D. nigrescens (T, 2r)8, 205, 

 2(')(i). While travelling over the Cuyamaca Mountains east of San Diego, in 

 A])ril, 1872, Dr. trooper found ]>. nrr/c/cjild/ii, for the tirst time, (|nite common. 

 They seemed to be still migrating during the last week of April, but perha])s were 

 only moving upwards, being numerous between the elevation of ],'}()() and 4,000 

 feet, while heavy frosts still occnrred at the latter height. They probably go in 

 May as high as (),L'O0 feet, the sunnnits of the highest peaks, which are densely 

 covered bv coniferous trees. J). tuii'iiKi-inU and 1). iiliiri'Kccus were in com|)anv 

 with (icridi'nOtlis in small flocks, among the oaks, and all seemed to be following an 

 elevated route northward. In 18(i2, Dr. Cooi)er found them among the chapaiTal 

 'ilong the coast, but he regards this as excei)tional and probably occasioned by iv 

 severe storm in the mountains, as he saw none in 1872 in a spring of average 

 mildness. Thoy occur al)out Petaluma as early as .\])ril I. 



Seiurus ludovicianus (I, 2S7). Mr. E. Inger.soll met with the nest and 

 eggs of the Large-billed Thrush near Norwich, Conn. The nest was sunk in tlio 

 ground, in some moss and in the rotten wood underneath the roots of a large tree 

 on the banks of the Vantic IJiver. it was covered over, except just in fi-ont, by 

 the roots. The nest was 2i inches in internal diameter and rather shallow, and 

 was somewhat loosely constructed of fine dry grasses and little dead iibrons 

 mosses. About the nest, but forming no part of it, were several loose leaves. 

 These were chiefly in front of the nest, and served as a screen to conceal it and its 

 occupant. The nest itself was placed tnider the edge of the bank, about ten feet 

 iibove the water. The eggs were four in mnnber and were cpiite fresh. Unblown, 

 they have a iieantiful rosy tint, the groinid-color is a lustrous white, the egg hav- 

 ing a })olished surface. They are more or less j)rofusely spotted all over with dots 

 and specks, and a few obscure zigzag markings of reddish-brown of two shades, 

 and umber, with faint touches of lilac anil very pale washing of red. These mark- 

 ings are much more thickly distributed about the largi'r end. but nowhere form a
