| Plate tectonics gave a great stimulus to marine geology and geophysics; in the years since its enunciation there have been major drilling programmes, a new science of global palaeoenvironmental oceunography and much more detailed oceanographic surveYs. The pace shows no sign of slackening-in the next few years the passive continental margins will be muchstudied. [NOT CONTROLLED OCR] |

The problem has also become more complex as more and more natural resources are subjected to more intensive multiple uses.

| A Harbour Porpoise, Phocoena phocoena, taken from near Shallow Bay, Mackenzie River Delta, Northwest Territories (68°48’ N 136°35’ W) in July 1973 represents a range extension 800 km eastwards from the previous extreme northeastern record on the north Alaskan coast. All 12 Harbour Porpoises so far examined from either the extreme north of the range of the species in the eastern North Pacific Ocean, or from the extreme south of the range in the eastern North Pacific and eastern North Atlantic Oceans, are large animals. |

| A key is provided covering only those species of Mortierella of which living cultures are available and which are recognized as specifically distinct. Two subgenera, Micromucor subgen. nov. and Mortierella, and nine sections in the latter are distinguished. The recognized species are listed with some new synonymies and bibliographic documentation. Three species which were invalidly published by Linnemann in 1936 are validated. |
