the open where I could see them. One of these I shot but by mischance 

 destroyed it. 



In 1940 Carriker secured one from a boy at Tres Zapotes on Jan- 

 uary 26 and shot another in heavy forest on March 3. Two more were 

 collected on Cerro de Tuxtla on March 11 and 29 between 1,000 and 

 2,500 feet elevation. 



HYLOCICHLA USTULATA USTULATA (Nuttall) : Russet-backed Thrush 



Turdus cestulatus [=ustulatus] Ntjttaix, A manual of the ornithology of the 

 United States and Canada, ed. 2, vol. 1, 1840, pp. 400, 830, and vi (Fort 

 Vancouver, Wash.) 



It is a matter of special interest to examine a female taken by 

 Carriker at Tres Zapotes on January 29, 1940.

Hylocichla ustulata almae Obeeholsee, Auk, Oct. 1898, p. 304 (east Humboldt 



Mountains, Nev.). 



Carriker shot a male on April 16, 1940, between 2,500 and 3,500 feet 

 elevation on Volcan San Martin.

 p. 998 (Jalapa, Veracruz). 



Carriker found these birds on the Sierra de Tuxtla, where he se- 

 cured his first specimen on March 29, 1940, at about 2,000 feet elevation 

 on Cerro de Tuxtla. This individual flushed from the ground in thick 

 underbrush and alighted nearby on the ground. On Volcan San 

 Martin he secured a pair on April 16 between 2,500 and 3,500 feet 

 elevation. They seemed more common here but, as usual, were shy 

 and difficult to secure. They were building nests at this time.

POLIOPTILA CAERULEA CAERULEA (Linnaeus) : Blue-gray Gnatcatcher 



Motacilla caerulea Linnaeus, Systema naturae, ed. 12, vol. 1, 1766, p. 337 (Phila- 

 delphia, Pa.). 



As migrants from the north, we secured specimens of the blue-gray 

 gnatcatcher at Tres Zapotes on March 8, 1939, and January 18 and 

 March 4, 1940. Carriker shot one at Tlacotalpam on February 7, 

 and another at 1,800 feet elevation on Cerro de Tuxtla on March 19. 

 The specimens have the following measurements: Two males, wing 

 51, 51.4, tail 46.9, 49 mm.; three females, wing 50, 50.2, 51.4, tail 

 46.2, 48.4, 49.5 mm.
