Abstract The Collembola collected in Kerguelen Island comprised three forms. One was a species of Isotoma, apparently, but the examples were not in a condition to be determinable with certainly. One was a Smynthurus. In this genus the forms of the feet and of the saltatory apparatus afford good specific characters. There being only one specimen in the collection, this was sent to a professional mounter of microscopic preparations. Unfortunately it was put up with the legs bent under the body so much as to prevent the feet being examined; and in attempting to rearrange the specimen so as to show them, he destroyed it. Under any circumstances, however, it would have been unsatisfactory to describe a new species of Smynthurus from a single specimen, and without knowing the true colour. The only example was obtained under a stone near a lake not far from the chief English Observatory, in January.
