Stacheoceras Romanowskyi Karp. 

 Thalassoceras sp. ind. 



This list does not leave any doubt that the fauna really corresponds 

 in age to that of the Artinsk sandstone. If our conclusions are right, 

 the Darwas fauna would correspond to that of our Hess limestone or 

 zone of Prothalassoceras. 



A very similar fauna seems to have been found by Wanner^ at 

 Bitaunu in the district Maubesi on the island of Timor. These strata 

 contain hundreds of Agathiceras, large Gastrioceras, Popanoceras, 

 Propinacoceras, and Parapronorites aff. Konincki Gemm. The fauna 

 is apparently very similar to that of the Sosio beds and probably 

 synchronous v/ith it. 



The Chinese localities which carry ammonoids seem to belong mostly 

 to the Permo-Carboniferous, but the few cephalopods so far found 

 do not allow the exact determination of the horizon. 



The famous fossil-bearing strata of Lo Ping only yielded Gastrio- 

 ceras (?) Richthofeni Freeh, a not very characteristic form, on which 

 a conclusion as to the age of the beds cannot be based. 



In the lower part of his section of Ta-Pa-Shan, near Tshau-Tien, 

 province of Sz'-Tshwan, Richthofen discovered a number of spiral 

 tests which have been determined by Freeh as Agathiceras cf. Suessi 

 Gemm. and Gastrioceras cfr. Zitteli Gemm. These fossils do not 

 leave much room for doubt that those strata correspond either to the 

 Sosio beds or the Artinsk sandstone. 



Some very peculiar ammonoids have been found by Richthofen nea*- 

 Ning-Kwo-hsein, province of Nyan-hwei. Freeh has described one 

 of them as Paraceltites pseudo-opalinus Freeh and thinks that iht. 

 other form is a new genus similar to Gastrioceras. He supposes that 

 the strata are more or less of Artinskian age. 



A very interesting fauna from the Himalayas has been described 

 by Diener. The fossils were collected in the Productus shales near 

 Lilinthi by F. H. Smith. Diener describes the following species: 



Hyattoceras nov. sp. ex. aff. H. Cumminsi, White. 



Adrianites {Hofmannia) sp. ind. 



Gastrioceras sp. ind. ex aff. G. Marianum, Vern. 



Pericyclus sp. ind. 



LilintJiiceras nov. gen. sp. ind.
