Nothing of the habits of this species is known, nor even its 
original home. It is generally understood to have been introduced 
with plants from abroad. Specimens have generally been found 
in hothouses of low temperature, and Professor Moseley, basing 
on temperature, suggests Japan or China as the country of its 
origin. 
The specimens which I have the pleasure to place before you 
were taken at Woodside Gardens, Paisley, where this species has 
been noticed less or more plentifully during the last three or four 
years. This, I believe, is the first record of its appearance in 
Scotland. 
T have been able to take the following observations, hitherto 
unrecorded, regarding this species :—It is of nocturnal habits ; 
any captures that are made during the day seem to be of animals 
in a dormant condition, as they are curled up in what seems a 
resting position. Hitherto heat has been looked upon as essential 
’ to its existence. but that is not, or at least does not seem, necessary, 
as specimens have been taken in an open border when the ground 
was frost-bound and the temperature considerably below freezing 
point. At the same time they are generally taken in a house 
the temperature of which ranges between 40° and 45° Fahr. They 
are not injurious to plants as far as known, and are lovers of 
moist places. It is certain, I believe, that they breed at Woodside, 
specimens having been taken from two inches upwards, but as yet 
I have been unable to gather any particulars regarding their food 
or the production of their young. 
With regard to the original home of this species, I may state 
that a large consignment of plants was received direct from Algiers 
in the year 1890—previous to the appearance of this planarian. 
One, if not more, of the places recorded in England received 
plants from Kew, and it is thought that it may have been trans- 
ferred with these consignments ; but that is not the case with the 
Scottish record, no plants having been received from that source.
