at an hour of daylight when he was free from business he would 
decline, with his regrets that he could not accept, as “the tide did 
not come just right for it that day,” and he would start again for his 
favorite shore or stream. 
In the present publication the record will not be in chronological 
order, but by species; the marine and fresh water forms from Con- 
necticut localities being in separate lists. Under each species (or 
variety) will be given the numbers, the localities and the dates; and 
where specimens of the number in question were distributed in the 
Phycotheca Boreali-Americana, this will be indicated by the initials 
P. B.-A., with number. Notes made by Mr, Holden on special 
points of habit, structure, etc., will be given in quotation marks. 
After the Connecticut lists a short list will be given, representing 
collections made in Newfoundland, in July, 1897. Collections made 
during short visits to Mount Desert, Maine, Wood's Hole, Massachu- 
setts, etc., have been already utilized in other publications. Published 
lists of algae are too often restricted to mere names; where a locality 
is given it is often only a town name; and any indication of time of 
occurrence is rather exceptional. The more recent European works 
give fuller details in these matters, as well as in regard to the envi- 
ronment favorable to a particular species; but in American publica- 
tions little of this is to be found; a beginning, at least, can be made 
in this case. The month will always be given, but not the year; 
where there are notes as to fruit, the month for that will also be indi- 
cated, and the locality will be given with the utmost exactness pos- 
sible. That so few exact localities are on record for algae seems 
strange, as there are no plants for which exact details are so desir- 
able; a flowering plant in bloom is a conspicuous object, easily noted 
as one walks or even rides along; ferns are much the same, and even 
small Botrychiums can be found by getting down on one's knees; the 
larger fungi stand out plainly, the micro-fungi are associated with 
definite hosts; but with algae, especially with fresh water algae, the 
case is different. The stream in which they grow may be invisible 
to one walking a few rods away; in the pond there may be many spe- 
cies, sometimes mingled, sometimes in zones of depth, sometimes one 
at one point, another at another; often a species is persistent year 
after year in a very limited locality, and not elsewhere. The flower- 
ing plant or the fern is at once recognizable, or at most the question 
is between two or three critical species ; but it is different with fresh
