The little crab Hymenosoma lacusiris was previously known to occur in New Zealand only in a small freshwater lake near the coast, but it has also been recorded from streams in Victoria and in Norfolk Island. In the following list I have given only the most important references under each species. B r a c h y u r a . H ymenosoma lacustris (Chilton). Elamena (?) lacustris Chilton, Trans. N. Z. Inst. xiv. p. 172. Hymenosoma lacustris Chilton, I. c. xv. p. 69, pi. i. fig. 2. Hymenosoma lacustris Fulton & Grant, Proc. R. S. Viet. xv. (new series) p. 60, pi. viii. One male and one female specimen from Lake Waikare, the male taken on the stony shore, the female in 5 feet of water. These resemble the typical specimens from Lake Pupuke Auckland, except that the posterior tooth of the carapace is quite absent and the anterior one forms a slight projection ol the Outline of the carapace rather than a definite tooth. This species has been found in freshwater streams in Norfolk Island and in Lake Colac in Victoria. A full account of the slight differences observed between the specimens from different localities will be found in the paper by Messrs. Fulton and Grant mentioned above. M a c r u r a .

Numerous specimens from Lake Waikare, from nettings among reeds *, This species is common in freshwater streams throughout the main islands of the Colony ; I have specimens also from the Chatham Islands.

Mr. Thomson records it from the Kaikorai lagoon (brackish water), estuary of Waikouaiti River, and rock-pools at Brighton-all * In the tube with this specimen was a single example of a terrestrial Isopod, Porcellio scaler Latr., an introduced species which must have got among the collections from the lakes b}r some accident.
