THE NAUTILUS. 71 



The doctor is a delicate man of 60 whose health is none the 

 best, and when he first proposed to go tramping with me I felt 

 very doubtful whether he would be able to endure the hardships 

 of such a rough-and-tumble life. Instead of lying down and 

 resting that evening he took a long walk through the pine 

 woods apparently for mere relaxation. In our various excur- 

 sions I found him always ready to lead, and he never gave any 

 intimation that he felt the slightest fatigue. 



We pitched our tent on a growth of sedges (Eleocharis), so 

 dense and tall that we could walk on it without pressing it to 

 the ground an admirable bed. Then we crawled in and after 

 driving out the mosquitos carefully closed, as we thought, every 

 aperture and congratulated ourselves on the prospect of a fine 

 sleep. I did sleep but uneasily and was vaguely conscious that 

 the doctor was much disturbed. When daylight came we could 

 see that the inside of the walls and roof of the tent were so 

 covered with mosquitos gorged with our blood that in places 

 one could not have put his finger on them without touching an 

 insect. We discovered a minute opening, just large enough to 

 admit them in single file, and they had been industriously pass- 

 ing in all night. 



We searched some small hammocks which lay to the north- 

 west of us without results and then turned southward along the 

 shore, finally reaching the great Watson's Hammock. Form- 

 erly this covered a considerable area and consisted of a magnifi- 

 cent growth of tall, closely-set tropical trees. Much of it has 

 been cut out; but there still remains a splendid remnant, and 

 this we diligently searched but found only a few faded bones. 

 I first visited this forest in 1885, arriving just before sundown. 

 My boatman who was anxious to get on only consented to 

 allowing me a few minutes on shore, but during that brief time 

 I could see that the trees were full of splendid Liguus. Had I 

 been allowed a little time I could have actually gotten "a hat- 

 ful. " As it was I found the type of my Liguus solidus crassus, 

 a form with a very solid shell and truncate columella, ivory 

 white with a narrow bronze-green peripheral line, also a couple 

 of specimens of the form graphicus. 



We struck off down the island in a general southeast direc-
