Ascidians were collected in Tanzania in January 1996 by SCUBA diving. Among 31 species reported here, nine are new. Several species were also recently collected in Mozambique. Full descriptions are given with figures and colour plates. The present collection of Tanzanian ascidians significantly increases the number of species known in the tropical western Indian Ocean, and enlarges the range of other ascidians previously unrecorded from the Indian Ocean.

Working on the flora and vegetation of Mt Kilimanjaro, Tanzania, 17 ferns in 10 families were found that had not yet been recorded for the floral region T2. The altitudinal range, localities and habitat description are given for Adiantum raddiancm, Asplenium bugoiense, Blechnum ivohibense, Blotiella stipitata, Dryopteris antarctica, D. fadenii, Sticherus flagellaris, Hymenophyllum splendidum, Trichomanes borbonicum, T. chevalieri, T. ramitrichum, T. rigidum, Elaphoglossum spathulatum, Lomariopsis warneckei, Pneumatopteris unita, Sphaerostephanos unitus and Xiphopteris spec. A.

This paper reports on the occurrence of Syrphidae in East Africa (Kenya, Tanzania, Uganda), based on 5,600 specimen records incorporated in the biodiversity database of the National Museums of Kenya. In total, 219 species are reported from the region with 171 in Kenya, 123 in Tanzania and 127 in Uganda. The similarities between the faunal composition of the three countries, as well as the endemicity are discussed. Based on GIS mapping of the database records, distribution patterns and zoogeographical relationships are discussed.

A survey in medium altitude primary forest yielded eleven species of termites in three families. At least three species are mainly West African. Low levels of termite consumption were observed in woody litter on the forest floor, but relatively high levels of attack on standing wood in the canopy were inferred. The chimpanzees are not known to eat termites at Kibale, but this is probably because no suitable species are present. Land that had been cleared of forest had a very different termite fauna.

This checklist records the 99 species of lizards known at present from Kenya, and which are divided amongst eight families: Gekkonidae 33 species, Agamidae seven, Chamaeleonidae 17, Scincidae 22, Lacertidae 12, Cordylidae five, Varanidae two, Amphisbaenidae one. Brief data on the distribution of all species is given, with some localities, details of habitat and (in some cases) status of subspecies. Some taxonomic notes on certain problematic species/genera are included, plus a brief discussion of the zoogeography of Kenya's lizards, and a gazetteer of localities.
