Abstract
REPORTS 8 and 9 of the Marine and Biological Survey of the Union of South Africa for 1929-31 include two special reports as well as a large collection of important fishery statistics. The latter is the result of extensive investigation over the 2,500 miles of coast from St. Lucia Bay to Walvis Bay. In a valuable paper on the “Post-Brephalus Development of South African Macrura”, W. von Bonde describes the various phyllosoma and puerulus larvae of the Palinuridae, Panuliridae, and Scyllaridae of this region. The work is well illustrated, and contains interesting notes on the development of the nervous system. It is unfortunate that the method of describing larvae from the plankton samples does not permit of identification of species. Much experimental work on these lines remains to be done. In the second paper, on “Hydrographical Investigations in South African Seas”, J. M. Marchand makes a survey of the variation in temperature and salinity throughout the years 1929-31. He notes the effect of the Mosambique and Benguela currents on the coast of the sub-continent, but it is naturally impossible at present to make more than very broad generalisations when working over such a large area.
