sider the huudred foot contour as the line marking in general the 

 boundary between the cypress swamps and the pine barrens, and 

 conseejuently the boundary of the present distribution of the 

 I , ory-billed Woodpecker. 



As before stated, the species is confined almost entirely to 

 country below the hundred foot line, but there ai^e a few extra- 

 limital records that are worth considering ; these are the Missis- 

 sippi Valley records for Newport, Arkansas, (elevation from one 

 hundred to five hundred feet above the sea), and Fayette and Kan- 

 sas City, Missouri, (altitude six hundred and fifty and seven hun- 

 dred and fifty feet respectively) which are explained by the fact that 

 in this vast river basin the slope is so gradual that the cypress 

 swamps in which the bird delights extend farther into the in- 

 terior of the country. 



Beginning now in North Carolina, with Fort Macon and 

 Wilmington, we pass into the pine barrens* of upper South 

 Carolina where Dr. Burnettf mentions it as being resident in 

 1S51. In the collection of Mr. G. N. Lawrence, is a pair taken 

 near Charleston about forty years ago by Mr. John G. Bell. Mr. 

 Lawrence writes that at the time they were procured the species 

 was quite abundant, but that few, if any, are to be found there 

 at the present time. J Coues mentions it as "Resident but ex- 

 ceedingly rare," and "chiefiy confined to the lower country." 

 Mr. Walter Hoxie writes that prior to 1870 it was common un 

 the Hunting Islands, but is now an exceedingly rare visitor; one 

 specimen was taken on Johnson's Island in March, 1879 or iSSo, 

 and two years ago (1888) one was seen on Fritchard's Island. 



In Georgia the records are extremely scarce, the only one at 

 hand being the nest found by Maurice Thompson, already cited ; 

 his was in the southeastern part of the State in the Okefinokee 

 swamp, but lacks the important item, th,- date. 



Next in line comes Florida. In no other State is the pine 

 line § so well marked or so closely connected with the distribu- 



* The pine barrens of upper South Carolina consist for the most part of the follow- 

 ing counties: Burnwell, Darlington, Marion, Marlborough, Orangeburg, and Sumter.

^ It may be well to state specifically what is termed the pine line. To begin with? 

 such a line is extremely difficult, if not next to impossible, to locate, as pine penetrates 

 he cypress in the low lands for a gi eater or le^s distance at every point ; while, on the 

 other hand, cypress ceases entirely as soon as higher ground is reached, and it is this 

 line marking the limit of the cypress that I have attempted to show and to define.
