BIEDS OF AEGENTTNA, PARAGUAY, URUGUAY, AND CHILE 253 



December 7, 1920. Others were noted December 8 and 9. If the 

 genus Eremohius^ of Gould (1839) be considered preoccupied by 

 Eremohia Stephens,^^ applied to a group of insects, then the bird 

 under discussion here must bear the name Enicomis Gray.^'' 



Heiiicornis wallisi Scott ^^ in all probability is a synonym of ipliocn- 

 icurus since the type locality, Arroyo Eke, is in central Santa Cruz, 

 not far distant from the coast. Salvador! ^^ states that, according to 

 Hellmayr, Scott's form is of doubtful validity, as three specimens in 

 the Tring Museum differ from phoenicurus only in having the mid- 

 dle rectrices " wholly brown or with but a small ferruginous patch at 

 the base of the inner web." The types of E. phoenicurus in the 

 British Museum are said to have the whole basal portion of the 

 middle rectrices, on both webs, ferruginous. The skin from Zapala 

 has the bases of the central tail feathers mottled faintly with fer- 

 ruginous. Until more material is available this faint distinction is 

 considered merely individual variation. 



The type of Enicomis striata Allen (Bull. Amer. Mus. Nat. Hist., 

 vol. 2, Mar. 22, 1889, p. 89), which I have seen in the American 

 Museum of Natural History, described from a specimen brought 

 back by Doctor Rusby, of unknown locality, ascribed questionably to 

 Valparaiso, on examination proves to be U pucerthia ruficauda. 



Near Zapala these birds were found amid patches of low thorny 

 brush that grew on the slopes of rolling hills, where the soil was 

 composed of sand and stones. Here they worked secretively under 

 cover or ran along on the ground with the tail cocked at an angle 

 over the back. Occasionally one flew with tilting flight to a secure 

 retreat passing only a meter above the ground. In general ap- 

 pearance they suggested long-tailed wrens but were more terrestrial. 

 Their call was a low clicking note. (PL 17.)

Near San Vicente, Uruguay, on January 29, 1921, as I came down 

 to a small stream in a rocky, heavily wooded gulch a small bird came 

 out curiously to meet me, and then retreated to the somber shadows 

 behind. With its sooty brown coloration it was difficult to dis- 

 tinguish in the cover, now dank and dripping from heavy rains, 

 that it frequented, so that several times it had moved along while I 

 was still trying to make out its dull-colored form on the perch 

 recently occupied. Wrenlike in form and wrenlike in actions it
