splotchy rather than puiictulate. The eggs are rounded-ovate and 

 measure in millimeters 14.0 by 11.7, 14.6 by 11.8, and 14.0 by 11. <i. 

 Only the female parent was observed in the vicinity of the nest and. 

 as noted by Oilman, there was a notable lack of e.xpres.sed anxiety. 

 The bird merely remained amont;' distant mesijuites, uttering an occa- 

 sional faint, one-syllabled alarm note. 



Twenty-tive specimens ol' this wai'hliT were obtained, nos. 13o7!)-

The Lucy warlilei' was originally discovered at Fort Jlohave. which 

 is on the Arizona side of the river. Its describer, J. G. Cooper (1861. 

 p. 120), remarks as follows: "This bird was common at Fort Mojave, 

 near Lat. 35°, in the Colorado Valley, where it arrived about March 

 25th. and remained until I left there, the twenty-eighth of May. I saw 

 none along the Mojave river, on the route westward. I collected five 

 male specimens and one female." 



Two of Cooper's specimens ai-e in the Museum collection : female, 

 no. 4266, April 5. 1861; male, no. 4267, April 11, 1861. These may 

 with propriety he considered co-types, at least. Although no sin'.;le 

 specimen had been designated as type, Ridgway (1902, p. 474) indicates 

 that a specimen which he considers the type is in the United States 

 National Museum; this is probably one of the five nudes I'cfei'red to 

 by Cooper. Both our specimens have the original label, on faded blue 

 note-i)aper, giving full data, entirely in Cooper's own handwriting. 

 The female has "luciae. n.s. Cooper" in one corner in the same faded 

 ink as on the rest of the lal)el. except that both specimens have 

 "luciae, J. G. C." interlined in blacker ink. just beneath the original 

 "Ilelminthophaga." eviib'utly inscribed liy Cooper at some later time. 



Vermivora ruficapilla gutturalis (Ridgway) 

 Calaveras Warbler 



First noted April 7 to 9. on the Arizoiui side of the river, ten 

 miles below Cibola. Here they were not imcommon in the upper foliage 

 of blossoming willows. Next observed on the o|)posite side, twenty 

 miles north of Picaeho, April 11, with similar mode of occurrence; 

 then five miles above Laguna, April 25, and at Potholes, April 29. 

 Here, and four miles south of Potholes, up to May 2, this was one of 

 the commonest warblers. One was seen five miles northeast of Yuiiui, 

 Mav 3; and in the vieinitv of Pilot Knob, ^lav 6 to 15. a few were
