Type. Adult female. B.M. no. 8. 10. 6. 8. Collected 27th 

 July, 1908. 



There is no doubt that this Nigerian form must be recog- 

 nized as distinct from the Gambian species both on account 

 of its smaller size and larger upper anterior premolars. 



I propose to call it Chcerephon websteri, after the donor of 

 the collection.

The following communication was read : — 



' On some Fossil Fishes discovered by Prof. Enues de Souza 

 in the Cretaceous Formation at Ilheos, State of Bahia (Brazil).' 

 By Arthur Smith Woodward, LL.D., F.R.S., F.L.S., V.P.G.S. 



This paper proves that the Lower Cretaceous formation of 

 Bahia extends along the coast, to a point at least 130 miles south 

 of the area previously described. The fish-remains are referable to 

 new species of the genera Maivsonia, Lejjidotus, and Scomhrodupea. 

 Maivsonia seems to have been scaleless, and differs from all known 

 Jurassic and Cretaceous Coelacanth fishes in lacking denticles on 

 the fins. The Lepiclotus closely resembles the European Wealden 

 L, ManteUi in proportions, but is more strongly ornamented. The 

 Scomhroclnpea is peculiar, in exhibiting only scales where the anal 

 finlets usually occur.
