A few pass the winter. — (I), svperciliosa, Dresser, Ibis, 1865, 478. — D. 

 dominica albilora, Sennett, B. Rio Grande, 13.) 



31. Dendrceca pennsylvanica, (Linn.) 

 Several seen in April and May. 



32. Dendrceca striata, (Forst.) 



A single specimen taken in August. 



33. Dendrceca castanea, (Wils.) 



Not rare in the spring migration. — (Dresser, Ibis, 1865, 478.) 



34. Dendrceca virens, (Gmel.) 



Taken in May and November.— (Dresser, Ibis, 1865, 477.— Sen-

March 31, 1877.— (Sennett, B. Rio Grande, 13.) 



37. * Geothlypis trichas, (Linn.) 



Found throughout the year. Summer birds approach var. melanops,

38. Geothlypis Philadelphia, (Wils.) 



A female taken within the fort on September 7, 1877. — (Dresser,

39. *Icteria virens, (Linn.) 



A common summer resident, arriving at Fort Brown about March 26. 

 Here it is much more common than higher up the river. Individuals 

 breeding in Southern Texas arc decidedly smaller than those taken in 

 New England, bearing about the same relation to them that Icterus var. 

 affinis does to var. spurius. Thirty- three eggs average .87 x .64. — (Sen- 

 nett, B. Bio Grande, 13.)

Abundant during the migrations, returning in autumn about the 10th 

 of August.— (Dresser, Ibis, L865, 478.)
