around the head of Lake Michigan. The lake itself contains a Mysis, 
a marine crustacean!, And I have it upon the authority of Mr. T. H. 
Hubbell of the University of Michigan, that the dune grasshopper, 
Trimerotropsis maritima interior is an endemic offshoot of the coastal 
plain true species. A similar endemic offshoot is another member of 
the Orthoptera, Neoconocephalus robustus crepitans, and still another 
grasshopper, Psinidia fenestralis is found not only along the Atlantic, 
but on the shores of the Great Lakes and also west of the Mississippi 
where the soil is sufficiently sandy. And Mr. R. F. Hussey, who has 
collected animals in Berrien County, Michigan, informs me that one 
snake which is, in a general way, of the coastal plain, shows the same 
discontinuous range; it is the pilot snake, Heterdon contortrix. 
A TABULAR VIEW OF INLAND EXTENSIONS OF THE 
CoasTAL PLAIN FLORA. 
In conclusion, and in order to give a summary of the inland exten- 
sions of the coastal plain flora, I append a tabular view of the stations 
for each coastal plain species which is found along the Great Lakes 
and connected waters, so far as I am able to discover. Beside my 
work in herbaria, I have relied upon a large number of published 
floras?. I have tried to use discrimination with this second- and third- 
hand information, omitting species of great improbability and using 
question marks in the case of plants which have, since being reported, 
been demonstrated by systematists to embrace more than one distinct 
species, so that it has become impossible to tell just what older writers 
had in hand when reporting such a species. Thus Lilium superbum is 
really a coastal plain species, but so many things have in the past 
gone under that name, that I have thought it best to leave it out 
altogether, despite persistent reports of its occurence inland. So
