Tayloria (Colpanostoma) leroyi ( Bourguignat, 1889)

Fig. 31

Colpanostoma leroyi: Bourguignat 1889: 43 , 48, pl. 1, figs 1–3 (Nguru Mountains, eastern Tanzania; 20× 25 mm).

A common species found at 12 stations inland, previously known only from eastern Tanzania. The sculpture below the periphery is much less pronounced. Some of the shells are practically smooth basally. The shell illustrated here has a 0.69 h/w ratio. However, some other shells collected in the region are proportionally higher. An unfigured shell from station 17, for example, has similar proportions (17.0× 21.5 mm, h/ w 0.79) to the type (h/ w 0.80). Another two similar Tanzanian species: T. usambarica Craven, 1880 and T. helicoides ( Boettger, 1913) do not have a sinuous lip.
