especially if the collections were extended over other months of 
the year. Some records of Hemiptera have been made, but they 
cannot be considered as in any way exhaustive at the present 
time. Extensive collections have been made of the Diptera by 
Prof. J. S. Hine, but no record as yet is published. 
It will be seen from this that scarcely anything has been done 
in the way of exhaustive study of any one of the groups of 
worms, crustaceans, mollusks, and a great majority of the groups 
of insects, in all of which we may be sure that there is an enor- 
mous aggregate of species represented. 
It appears to me that a systematic survey of the locality is not 
only possible but that with the large number of students visiting 
the locality each year we may hope for rapid progress, provided 
there is definite cooperation to that end. With regard to the 
value of such studies, we may say that the locality possesses some 
very unique features and is an exceptionally fine locality for flora, 
as has been shown by Professors Moseley, Kellerman and others. 
Many peculiar occurrences of animal groups have been noted that 
will greatly extend the main distribution of many of the species. 
To those familiar with the region it is unnecessary to speak of 
the peculiar and varied conditions presented, but for those who 
have never visited the locality it will be proper to state that the 
remarkable conditions are due largely to the presence of an 
extended stretch of sand — Cedar Point, which extends from six 
to seven miles and encloses the east arm of Sandusky Bay. This 
Point is virtually an extended sand dune, or series of dunes, with 
a flora entirely characteristic of sand dune formations ; that the 
arm of the Bay it encloses is to a considerable part an extended 
marsh so closely enclosed by islands, points and vegetable growth 
that the waters are very largely undisturbed. 
Within the other arm of the Bay we have the outflow of San- 
dusky River and a more or less rocky shore with limestone soil, 
which contrasts strikingly with the sand formations of Cedar 
Point. Another striking condition is offered in the level prairies 
in the vicinity of Castalia. On the whole there is, within a radi- 
us of five miles of the city of Sandusky, a variety of condi- 
tions which it would be hardly possible to duplicate anywhere in 
the interior of the United States, and which makes possible a 
great variety of biological studies. 
I may add that it is the purpose of the University to develop 
the biological station, and to this end it desires to make the sta- 
tion accessible and useful to every biological student and espe- 
cially those who are connected with the colleges and schools of 
Ohio. 
The members of this academy particularly should feel a sense 
of proprietorship in the station and are most cordially invited to 
take advantage of its opportunity.
