the suture between the whorls, and 
this determines it to be the species 
Hyalina radiatula. The third is still 
smaller, scarcely an eighth of an inch 
across, but we can easily tell it from 
the others by its white color, and the 
thick white rim round the mouth of 
the shell, called the lip. This is He- 
lix pulchella: in Canada, this snail is 
found smooth and shiny, but our 
specimens are delicately ribbed all 
over, and are therefore called variety 
costata. There are still two kinds to 
be examined, which are dark brown, 
and cylindrical, at a glance you would 
think they were seeds. They belong 
to the genus Pupa, but are not in 
good condition, and we will not try 
to name them until we have found 
better specimens. 
So much for the refuse thrown up 
by Grape creek. Now v^e will cross 
over the creek, and walk down the 
lane until we get near Joan Burke’s. 
*Now if we are not terrified by the fe* 
rocious locking animals he keeps to 
guard his mansion, we search in the 
ditch on the left hand side of the 
road. Soon we find some water snails, 
and they are Plivsse, too, because 
their shells twist to the Irft; but they 
are narrow and tapering, and a live- 
lier brown, evidently not the same as 
the species from the water barrel. In 
fact, they are Physa hypnorum, and 
rather larger and longer than is usual 
with specimens of that species. Now 
we have collected enough for to day. 
We have not been two miles from 
town, and yet we have found twelve 
kinds of snails. So there are some 
snails in Colorado after all! 
NOTES. 
With regard to the Colorado cab- 
bage flea beetle, of which we gave an 
account in our fifth report, Dr. Horn 
writes that although this has been 
called P’nvllotreta albionica, it is not 
the true species of that name, but an= 
other which he calls P. pusilla. Dr. 
Hor > does not think the true P. albi- 
onica is found in Colorado. 
Mr. Vernon Bailey, writing in the 
report of the Commissioner of Agri- 
culture for 1887, says he believes 
skunks to be beneficial, because they 
feed almost entirely upon insects. 
In our first report we gave the de- 
scription of a new beetle (Longitarsus 
nitidellus,) in which we stated that 
the antennae, were nine-jointed. We 
have now sent the specimen to Dr. 
Horn, and he reports that they are 
really eleven jointed. We have only 
ourselves to blame for the mistake, 
which arose through our using too low 
a magnifying power. 
We found a large puff-ball in Wet 
Mountain valley last year, and sdnt 
the specimen to Mr. J. B. Ellis, who 
replies that it “must be Mycenastrum 
corium. Your specimen is more 
pointed than others I have seen from 
your region, but the capillilium and 
spores are the same, only the threads 
of the capillitium are not quite as 
spiny.”
