The morphological characters separating these two species are not very striking. They differ in the degree of hooking of the beak, serration of the margin, development of the femoral tubercle, etc., characters which may be entirely valid but which it is easy to imagine being bridged by intermediates. Coloration also differs, but not so impressively as between si gnat us and Atlantic Ocean ^ signatus â boulengeri â¢^ femoralis O areolotus Fig. 38. Distribution of the species of Homopus in South Africa. (P. Washer del.) We have not seen the specimens from Cradock district identi- fied as areolatus; it is somewhat astonishing to find areolatus in- vading the highlands at well over 2000 feet, entering an unusual ecology at just the point where its closest relative occurs! We suggest that the alleged coexistence of femoralis and areolatus in the district be re-investigated. Cradock specimens (seen by one of us) in the British Museum are clearly femoralis but lack the serrate margin mentioned hj Boulenger in his original de-.
