Conversely, with one exception all specimens with an anteriorly opening lamina were collected from south of this latitude. The single exception came from Kanarok Hot Springs, Karamoja, Uganda (' N ' E). Here four specimens had posteriorly opening laminae and one (BM. ) had the anterior type. The distribution of these two lamina types is shown in Fig. 10. The lamina type with two islands was found to be randomly distributed throughout the taxon's range, whilst the first lamina divided into a small anterior island and a large posterior island was found in a single specimen from Sumbawanga, Tanzania (' S ' E). The above findings agree with Petter (1959) and Davis (1966) who found that T. valida from the northern savanna could be separated from those from the south by lamina type. In the present study the two populations, which would appear to be geographically discrete, are considered to be distinct subspecies, although the exact rank in the taxonomic hierarchy of such allopatric populations is difficult to deter- mine. The southern race is the nominate and includes in its synonymy the forms; neavei, liodon and taborae. The northern race is T. v. kempi and includes the forms ruwenzorii, beniensis, l
