92. Ammodramus savannarum intricatus Hartert. 



Nine specimens, both sexes, Arroyo Savanna. 



This species was found only on a large savanna, twenty-five miles 

 southwestward of Cabrera; here they were not uncommon. 



The Santo Domingan race was described by Hartert (Bull. B. O. C, 

 19) from specimens taken by A. H. Verrill at El Valle, S. D., January 

 16, 1907. All the diflFerences pointed out by Hartert appear to hold 

 good in my series, in fact the difference in color between it and A. s. 

 savannarum is so striking when viewed in a series that the bird might 

 almost be raised to full specific rank. 



In notes and habits the El Valle Grasshopper Sparrow resembles 

 the North American bird. Breeding probably commences late in 

 March. In specimens taken at Arroyo Savanna, March 8 to 10 the 

 sexual organs show signs of activity, moreover the males were con- 

 stantly singing.
