COCHLICELLA VENTRICOSA Drap., NEAR CHARLESTON, S. C. 



BY WM. G. MAZYCK. 



On the afternoon of October 27, last, I found a small colony of 

 this species living under a fallen fence post on a lot in the rear of 

 the United States Life Saving Station, in the town of Moultrieville, 

 on Sullivan's Island, at the entrance to Charleston Harbor, S. C. 



The discovery is one of peculiar interest, presenting a problem of 

 somewhat difficult solution. The island is quite small, being only 

 about four miles long, with an average width of some 300 yards 

 and an average height above mean high water of only about six 

 feet. The only natural growth of shrubbery is on the end, where 

 there is a dense growth of stunted myrtles. Moultrieville covers 

 about one-half of the Island. The lot upon which the specimens 

 were found is destitute of any vegetation, except a stunted growth of 

 a coarse low grass, somewhat similar in appearance to the ordinary 

 lawn grass ; there is no garden nearer than half a mile, and that 

 contains no plants of foreign importation. There is absolutely 

 nothing in the environment to suggest congeniality, and the spot is
