above, the suggestion can hardly be avoided that if environment 

 and cHmate be considered as affecting markings, it may lead to a 

 reconsideration of the value of such a basis for specific distinctions. 



An interesting illustration of regeneration was found in one of the 

 specimens taken (No. 6,339) in which the tail had been injured 

 75 mm. from the vent and a new tail 65 mm. long regenerated. The 

 old tail, however, still persisted, and projected at almost right angles 

 to a distance of 10 mm. with a small shriveled stump on the end 

 suggestive of a spine or barb. 



Several of the specimens of Plestiodon quinquelineatus were infested 

 with red mites (Acarina), which appeared attached under the fore 

 legs. One individual had eight of these parasites under one fore 

 leg and twelve under the other.

The alligator was found to be extremely common throughout the 

 Okefinokee, and after the novelty of watching their interesting 

 habits had worn off, no particular attention was paid to them by 

 members of the party. Alligators were constantly being seen in all 

 parts of the swamp, and a short trip in any direction from Billy's 

 Island usually resulted in the noting of several specimens. Outside 

 of a few shot for their skins and those killed for food, no adults were 

 collected, as it would have been entirely impracticable to have 

 transported their heavy bodies out of the swamp. A number of 

 young were taken, and of these a half dozen or more were preserved. 



A trip down Billy's Lake, from Billy's Island to Mixon's Hammock, 

 was always the occasion for more or less sport in endeavoring to 

 approach the alligators as they lay on the banks, in following their 

 courses as they swam across the placid stretch of water, leaving 

 broad ripples in their wake, or in listening to the interesting vocal 

 gymnastics of the Lees as they endeavored by ''grunting" to induce 

 a specimen to rise to the surface. The reptiles were often seen 

 sunning themselves in the rank masses of vegetation, which lined 

 the shores and were not infrequently surprised at very close quarters 

 while they were swimming. 



Whoever has heard the bellowing of ''gators" on Big Water or on 

 Floyd's Island Prairie will ever remember it as one of his most distinct 

 memories of the swamp and need ask for little else more blood 

 stirring or thrilling upon first acquaintance. The Lees claim the 

 young ones can bellow nearly as loud as the older ones and that they
