While it is feasible that some of the introduced species recorded now might have become established as a result of contacts made by whalers and sealers earlier than the advent of the German expedition, it is unlikely that all would have done so. Unfavourable climatic factors and the absence of specialised breeding conditions would preclude survival of those listed except possibly Necrobia rufipes Fab. Krone mentions Dryophthorus tuberculatus Fab. taken on the “Alexandrine” and states that the species might have been brought either from Melbourne or New Zealand; this is evidently the New Zealand Mitra. stethus bituberculatus Feb. and as it has not yet been recorded as occurring on the islands, it is excluded in the faunal representation. All the other species concerned are associates of stores of ships of those times, and as the “Alexandrine” must have landed stores in considerable quantity, the species would be present in the vicinity of the camp. Those mentioned by Krone are given, along with his remarks.
Trogosita mauritanica Linnaeus
“Beside some remains which are found here and there in humus between mosses etc. I collected only one living specimen out of the damp swamp soil of the main highland towards the end of December.”
Necrobia rufipes Fabricius
“At the height of Pig Point between low damp scrub and grass tufts caught in a butterfly net, in January. In this place there was a settlement of N.Z. whale hunters in 1848–50. Animal remains, for instance, dolphin skulls and bones are still lying about between the ruins of some dilapidated huts.”
Calandra oryzae Linnaeus (Sitophilus)
“One specimen collected in our house on Auckland Island, probably accidentally introduced from Melbourne with rice husks, which were used as packing for provisions, or with our rice provisions themselves. Nov. 1874.”
