THE STOKES COLLECTION OF ANTARCTIC FOSSILS. 



Mr. F. W. Stokes, artist to the late Belgian Antarctic expe- 

 dition, collected in February, ig02, a few specimens of fossils 

 upon the Antarctic continent at Admiralty Inlet, Louis Philippe 

 Land, south of South America. These fossils are the first which 

 have ever been brought back by any of the expeditions to the far 

 south, and great praise is due Mr. Stokes for affording this 

 means of identification for the first time, of the age of sedi- 

 mentary strata upon Antarctica. The collection is not large, 

 containing scarcely more than a dozen specimens, but a suffi- 

 cient number of species have been recognized to determine 

 somewhat definitely the age of the strata containing them, and 

 to permit of important conclusions as to the faunal geography 

 of Upper Cretaceous time. In the study of the collection the 

 writer is indebted to Dr. T. W. Stanton, of Washington, for 

 valuable suggestions. 



The specimens were all collected from a talus slope. Most 

 of them occur in concretionary nodules of a very dense, fine- 

 grained brown sandstone, but the two specimens of Hamites are 

 from a coarser- grained glauconitic sandstone which is reddish in 

 color upon its weathered surfaces. The most perfect specimens 

 of Tubulostium callosiim occur completely weathered out, but the 

 same species also occurs in the brown sandstone nodules. The 

 original stratigraphic position of all the specimens was probably 

 approximately at the same horizon. 



As might be expected, several of the species prove to be unde- 

 scribed forms and are here described for the first time. The 

 species recognized are as follows : 



Lucinaf towtisendi White. 

 Lagena ? antarctica, n. sp. 

 Tubulosthnn callosuni Stol. 

 Olcostephaniis antarctica, n. sp. 

 Haploceras? sp. undet.
