Vol. 6^.~\ CRETACEOUS FORMATION OF BAHIA. 131 



This is the farthest point from Bahia at which Cretaceous fossils 

 have been found in the cuttings of this railway. 



San Thome de Paripe. — Cretaceous conglomerates, sand- 

 stones, and shales, with the characteristic fossils, are seen in the 

 small semicircular bay of San Thome, which is reached from Olaria 

 Station (kilom. 13). The series corresponds with that exposed at 

 Setubal. In the sandstone near Toque Toque are thin layers of 

 fossilized wood, with fragments of resin. 



Santo Amaro and road to Alagoinhas. — Highly fossili- 

 ferous Cretaceous rocks occur in the neighbourhood of Santo Amaro, 

 and for nearly 8 miles along the road towards Alagoinhas. Scales 

 of Lepidotus are especially common, and entomostraca are found in 

 a bright-yellow clayey rock. 



The Timbo Railway. — This railway runs north-eastward from 

 Alagoinhas to Timbo, a distance of 83 kilometres. I have found 

 Cretaceous fossils in the cuttings between Kilometres 47 and 51, 

 and again at Kilometre 63 1, beyond which the rocks do not appear 

 to belong to the series under consideration. 



Ilha da Mare and the vicinity. — Entomostraca occur in 

 the yellow sandstone of Mochado, across a small arm of the bay 

 1 mile west of Mapelle. They are also found with fish-remains at 

 Ponta do Matoim. Scales of Lepidotus and crocodilian bones have 

 been obtained from a thick, massive, calcareous, yellow sandstone, 

 which overlies a bluish shale in the Ilha da Mare. 



II. The Vertebrate Fossils. [A. S. W.] 



The collections both of the late Mr. Allport and of Mr. Mawson 

 have been presented to the British Museum (Natural History), 

 where they can now be readily studied with ample material for 

 comparison. The vertebrate fossils, which are the more important 

 in this case for stratigraphical purposes, may be enumerated as 

 follows : —
