NOTES ON GUAITEjMALAN BIRDS^ — WETMOlRE 567 



HYLOPHILUS OCHRACEICEPS OCHRACEICEPS Sclater 



Hylophilus ochraceicpps, Sclater, Proc. Zool. Soc. London, 1859 (Feb. 1860), 

 p. 375 (Playa Vicente, Oaxaca). 



On December 4 these little birds were fairly common in swampy 

 thickets on a low island opposite Puerto Barrios. They w^ere quick 

 in fluttering flights from perch to perch, but when at rest they 

 remained quiet except for the quickly turning head. They were found 

 in pairs, though the male and female that I collected showed no 

 development of the sexual organs. 



Family COEREBIDAE 



DIGLOSSA BARITULA MONTANA Dearborn 



Diglossa niantana Dearborn, Field Mns. Nat. Hist., orn. ser., vol. 1, 1907, p. 125 

 (Sierra Santa Elena, 9,500 feet, near Tecpam, Guatemala). 



Near Sierra Santa Elena these interesting birds were fairly common, 

 being found in weeds and small bushes near the ground or higher up 

 in vine-covered trees. They were alert and active, keeping under 

 shelter and suggesting gnatcatchers somewhat in their mannerisms. 

 I heard a low song, which may be written tee tee tee tee^ that I at- 

 tributed to this species. The three taken here include two males on 

 November 18 and 23 and a bird in juvenal dress shot November 21. 

 At Maria Tecum, where I secured a male on November 24 at 10,000 

 feet, one that flew below me as I stood on a knoll appeared dark blue 

 above so that at first I did not recognize it. 



Wliile the male averages darker than Diglossa h. haiitula the 

 greater extension of the slate color on the throat seems to be the 

 most prominent character marking nwntana. 



I can see no justification for Hellmayr's action ^* in linking the 

 distinct Diglossa flumhea of Costa Rica as a subspecies of haritula, 

 since the charactei-s that join these two are of generic and not of sub- 

 specific value. 



Family COMPSOTHLYPIDAE 



MNIOTILTA VARIA (Linnaeus): Black and White Warbler 



MotaciUa varia Linnaeus, Systema naturae, ed. 12, vol. 1, 1766, p. 333 (His- 

 paniola). 



On November 1 I saw several in a wooded valley at 6,500 feet eleva- 

 tion on Volcan de Acatenango above Duehas, and on November 3 

 collected an adult male at 3,500 feet below Alotenango near the east- 

 ern base of VolcJin de Fuego. One was recorded near Chimaltenango 

 on November 7.
