 again to the east of Algoa Bay. 1 Plate XXV. is from a

 dorp coast. 



In addition to the usually fragmentary remains of 

 marine shells the dune limestones contain many fossils 

 of animals that lived upon land, and these are in a much 

 more perfect condition than the former. Snail shells, 

 especially a large species of Helix that is commonly 

 found living near the coast, are abundant in the lime- 

 stones of Saldanha Bay and the south coast. Mamma- 

 lian remains are frequently found, and they include 

 species such as the elephant, rhinoceros and eland, that 

 are no longer living in the neighbourhood. In the loose, 

 scarcely consolidated calcareous sand of the Darling 

 coast the remains of Bubalus baini and an extinct species 

 of Equus have been found together with the remains of 

 the rhinoceros and eland. 



In the Bredasdorp Division there is a prominent range 

 of dune limestone hills stretching from near the village 

 to Cape Infanta. 2 In their western part the hills lie 

 some twelve miles from the coast, and are separated 

 from it by a tract of low ground ; near the coast the 

 country again becomes hilly owing to the modern dunes. 

 The inland range must be of considerable antiquity, and 

 it is now being destroyed by the weather and rivers 

 without receiving any fresh material to compensate for 

 this loss. A bore-hole 262 feet deep at Victoria Dale
