ARREMONOPS RUFIVIRGATUS CRASSIROSTRIS (Ridgway) 



Emhcrnagra rufivirgata /3 crassirostris Ridgway, Proc. U. S. Nat. Mus., vol. 1, 

 1878, p. 248 (Mexico). 



We obtained a good series of this common resident bird in the low- 

 lands as well as several from the lower slopes of the Sierra de Tuxtla. 

 It is an inhabitant of thickets and undergrowth, not of heavy forest, 

 so that in the overgrown, abandoned fields common in this area it finds 

 extensive areas suitable to its needs. We noted it also in underbrush 

 at the borders of forest, and in such growth commonly found along 

 the cultivated fields. On the mountain slopes it ascended with the 

 clearing of the land for planting. In habits it is quiet, remaining 

 usually under cover and moving about slowly near the ground so that 

 it is easily overlooked. The song, given from a low perch under shelter 

 of leaves, is simple repetition of a single note that at the end becomes 

 a trill. 



PASSERCULUS SANDWICHENSIS SAVANNA (Wilson) : Eastern Savannah Sparrow 



Frvngilla Savanna Wilson, American ornithology, vol. 3, 1811, p. 55, pi. 22, fig. 3 

 (Savannah, Ga.). 



In February 1940 Carriker found these sparrows common in marshy 

 grass near ponds and lagoons near Tlacotalpam, taking a pair on 

 February 8. He shot a male at El Conejo on February 12. Probably 

 other forms occur here also. 



AMMODRAMUS SAVANNARUM PRATENSIS (Vieillot) : Eastern Grasshopper Sparrow 



Passerina pratensis Vieillot, Nouv. Diet. Hist. Nat., vol. 25, 1817 (Dec. 1818), 

 p. 24 (New York). 



On February 12, 1940, Carriker shot a female at El Conejo on an 

 open grass-grown slope in the sand dunes near the sea. One other was 

 seen. 



CHONDESTES GRAMMACUS STRIGATUS Swainson: Western Lark Sparrow 



Chondestes strigatus Swainson, Phil. Mag., June 1827, p. 435 (Temascaltepec, 

 Tableland of Mexico). 



On February 10, 1940, at El Conejo, Carriker found a small flock 

 and shot two, male and female. They were wild and difficult to 

 approach. On subsequent trips here they were not found.
