INVERTEBRATES OTHER THAN
INSECTS AND MOLLUSKS.

IN the following account I have tried to bring together the records for the district around Toronto. They are in most groups utterly inadequate to give a proper idea of the forms that are to be found here. I have included a few forms (indicated by an asterisk) which from their known distribution may be expected to occur here. When not otherwise indicated the identifications are my own. It is hoped that this may be of use as a basis for future records.
The well-known crayfishes occur abundantly and form an efficient corps of scavengers in all our streams and lakes. They form no inconsiderable element in the food of many of the fishes, frogs and birds.
