摘要:

The most recent evaluation of morphological variation inTyphlosaurus caecuswas based on only six specimens, including one from Port Nolloth here referred toT. vermis.We report on morphological variation in 25T. caecusand 33 T.vermisfrom several localities within their known ranges. The two species are allopatric and distinguishable on the basis of differences in head shield arrangement, numbers of scale rows round body, tail length/total length ratios, snout-vent length/body diameter ratios, numbers of subcaudals, and the position of the eye relative to the proximal end of the longitudinal groove in the rostral. All known locality records for the two species, including several new records, are documented and mapped.Typhlosaurus caecusis restricted to the coastal regions of the Western Cape province, whileT. vermisoccurs in the coastal regions of Namaqualand district, Northern Cape province. Although we confirm the identification of aT. vermiscollected about 400 km to the east of the nearest other record for the species, further collecting is needed to confirm this locality.

摘要:

Much of the available material of theMabuya quinquetaeniatacomplex from south of Latitude 5°N and east of Longitude 25°E has been examined.Mabuya margaritifera(peters) is reinstated as a full species, which is sympatric withM. quinquetaeniata(Lichtenstein) in southeastern Kenya.Mabuya pulcherrimaDe Witte is recognised as a full species in the Shaba Province of the Democratic Republic of the Congo.

摘要:

A new species of the Tanzanian ovoviviparous dwarf toadNectophrynoidesis described from the Kihansi River Gorge in the Udzungwa Mountains, and a key to the genus provided. The new species, currently known only from small patches of spray-dependent wetland vegetation associated with Kihansi Gorge waterfalls, is probably the most vulnerable member of this genus on account of the Lower Kihansi Hydropower Project which is due to go on-line in 1999. This project will significantly reduce the river flow into the gorge and consequently the amount of spray that maintains a unique plant and animal community. Measures are suggested for improving chances of long-term survival of the species.

摘要:

The recent collection of 13 specimens of the Tanzanian endemicAdenorhinos barbourimore than doubles the number of known specimens of this rare viper. Internal and external characters were examined in the older and the more recently collected specimens and character variation has been summarized. Based on limited information from collectors' notes and dissection of the alimentary canal,A. barbouriappears to be a species of the forest floor; both juveniles and adults prey on earth-worms and adults may also feed on anurans.
