NOTES ON AREA. 
Next to Area V, the juveniles found were most abundant 
here. Locality 6 in this area represents a re-juvenating bed 
at the base of Lake Pepin, clammed out years ago, and at 
that time producing many niggerheads. The only living 
specimen of R. granifera taken in the lake was secured at 
this place, although previously large numbers of dead shells 
were seen. At this point there was collected for the first 
time, Pleuwrobema Poyramidatum. Both localities 5 and 6 had 
comparatively few old shells in them. Locality 3 is shunned 
by clammers on account of the rocky bottom at this place, yet 
certain clammers who know the region are able to make good 
hauls here. Juveniles were fairly abundant. Specimens of 
Plagiola lineolata were particularly large. Fresh water 
sponges, and Bryozoa of species to be later given were also 
obtained here.
