Abstract

224 mentioned two other specimens which Mr. L. Glauert, the past Director of the Western Australian Museum, identified as H. armata. Only one of these latter two specimens could be located in the Museum collection in March 1965; this dry female (WAM 47.1950 from the Western Bight) was incorrectly identified by him and belongs to the species P.reudocarcinu.r gigas (Lamarck). - In the collection of the Western Australian Museum, there are four specimens of H. armata which have not previously been recorded. One female, 95 mm carapace breadth, between Fremantle and Geraldton, Western Australia, 1912 (WAM 4960); one male 150 mm carapace breadth, 12 miles north of Rottnest Island, Western Australia, in 25 fathoms, 24 January 1961 (WAM 17-65); one male, 145 mm carapace breadth, 10 miles west of Rottnest Island, April 1954, (WAM 315-54); one male 145 mm carapace breadth, no data. Reports by crayfishermen and processors in Western Australia suggest that there may be quantities of this edible crab in deep waters between Geraldton and Rottnest and on present evidence there is a possibility that it is more abundant on the west coast of Australia than on the south or east coasts.
