29.t Seiurus aurocapillus Swainson. Golden-crowned "Wagtail. 

 Not common. A few were seen in February, as well as later. 



30. t Seiurus noveboracensis NuttaU. "Water Wagtail. 

 Rare. Found at Dummitt's by Mr. Maynard in Februrary. 



31.* Geothlypis triehas Cabanis. Maryland Yellow-throat. 



Abundant. Though somewhat brighter colored throughout, they dif- 

 fer mainly from the northern type in the greater breadth of the black 

 facial band. There is but little difference in general size, that is, so far 

 as I have had an opportunity of observing ; occasionally a Florida 

 example has a bill considerably longer than the average in northern 

 examples, but this does not appear to be a very constant difference 

 between the southern and northern specimens. It would probably be 

 more marked in specimens from South Florida. 



Other species of this family were seen in March that are not to be 

 reckoned as winter residents. Amonsr them are the following : Den- 

 drceca maculosa, D. virens, and D. pennsylvanica, Euthhjpis cana- 

 densis, Setophaga ruticilla, and Hehninthophagg. ruJicapiUa, all of which 

 began to appear on the Upper St. John's, near Enterprise, about the 

 middle of March, and most of them were also seen later at lower points 

 on the river. Helmitherus vermivorus and H. Swainsoni were taken at 

 St. Augustine, by Mr. L. L. Thaxter, in April. 



HIRUNDINID.E. 



32.t Tachycineta bicolor Cabanis. "White-bellied Swallow. 

 More or less numerous, but observed at irregular intervals. Large 

 flocks were seen near the St. John's River in January. It probably 

 does not breed in Florida. 



33.t Cotyle riparia Boie. Bank Swallow. 

 Not observed by either Boardman, Maynard, or myself prior to the 

 last of March, but Mr. Audubon saw it in immense flocks " in winter," 

 first at St. Augustine, and afterwards in other parts of the State.* 



The Stelgidopteryx, serripennis was seen about Jacksonville the first 

 week in April, and specimens of it were obtained. Several pairs were 

 seen flying about some bluffs a few miles below the town, apparently 

 with the intention of selecting breeding-places.
