MISCELLANEOUS NOTES AND OBSERVATIONS. 
and Suffolk ; but while finding occasional tubes of Melicerta 
upon it have rarely met with the Floscule. My own experience 
is that it prefers the decidedly brackish and almost salt water 
to be found in ditches at the mouths of rivers. This, of 
course, does not apply to Lound Run and the lake at Fritton, 
but in these fresh-water situations the forms are not nearly 
so numerous or so fine as those found at Southtown which is 
a sure ground for them. In some recent gatherings I have 
simply taken a handful of Myriophyllum from a ditch and 
having separated two or three of the multiple leaves and 
placed them in a watch-glass or micro-tank, simply revelled 
in their beauties. I counted as many as 47 Floscules on one 
“ Frond ” (pinnate leaf), and as there are scores of these 
“ Fronds ” on one stem, the gregariousness of the animal can 
be better appreciated than stated. Under a Rousselet 
compressorium (the best way to examine the fixed Rotifers) 
and using a one inch objective I have frequently had as many 
as ten or twelve Floscules in the field at one time. This 
affords a unique and exceedingly fine opportunity of studying 
the animal as, if supplied with a fresh drop of water occasion- 
ally, it can be kept alive and under continuous observation 
for several days. 
April and May are the best months to find the Floscule in 
the above waters. — H. E. Hurrell. 
Lophopus Crystallinus. — Mr. H. E. Hurrell reports that he 
has found the Polyzoon in the river Yare in greater abundance 
than ever, and has taken it at both earlier and later periods 
than formerly. The statoblasts appear to be formed as early 
as the month of August, but are found more fully developed 
at the present period of the year (late October), and are 
probably at their best in mid-winter when the animal is slowly 
sloughing off the weed and the statoblasts are liberated.
