Revision of Indigenous Freshwater Fishes of Cape Region. 183 It is possible that the early colonists transported the white-fish from the Berg into the Breede Kiver, but the suggestion does not seem altogether plausible and is not based on any historical record. At the present day the lowest and least accentuated watershed between the Berg and Breede systems lies between the sources of the Little Berg River and the main Breede Eiver in the Tulbagh-Wolseley area (fig. 1, x ). Heavy flooding might have made intercommunica- tion possible. But, on the other hand, the topographic evidence. Fig. 17.—Barbus andrewi. Juvenile, 14 mm. Berg River. Dorsal spines of specimens 40 mm. and 70 mm. in length (length of spines 8 and 13 mm. respectively). (Only one row of serrations on the spines is shown.) shows that in former times the Little Berg River captured the true headwaters of the Breede River. Aberrations.—Two specimens have been examined which agree in nearly all respects with typical specimens; but if submitted to a systematist without any data, or long series of typical specimens for comparison, they would probably be regarded as a distinct, un- described species. One of 85 mm. length was caught in the Witte River valley (a tributary of the Breede River). The last dorsal spine is slender, flexible, and non-serrated. There are only 2 + 5 gill-rakers on the anterior arch. One of 95 mm. length was caught among a shoal of typical andrewi Berg River, but was captured by the energetic tributary of the Breede River cutting up through Bain's Kloof.
