wholly of granite, like that of Liu Ng. Not far below the pass 

 there had been a landslide from one of the mountains, and it gave 

 a fine chance to see the original constitution of the slope. I 

 suppose this sandstone may be Triassic, because it appears to be 

 unfossiliferous. The Chinese do not make vast excavations, but 

 they use stone for bridges, etc. In one place I crossed a new 

 bridge, made of red sandstone, and I examined the quarry from 

 which the stone came. If there were fossils found they would, 

 without doubt, be used as fetiches, and I should hear of them. 

 The natives said no queer thing had been found or seen in the 

 stones. There was no sign or speck of a fossil to be found about 

 the Cjuarry." 



The specimens of stone accompanying the notes were com- 

 mented upon by Prof Heilprin, who stated that they would be 

 the subject of further study and rejDort. The district here 

 described is an interesting one to geologists, inasmuch as it had 

 hitherto received but little attention upon the part of the travel- 

 ers. Much of the rock surface is probably identical with that 

 observed by Eichthofen in the region to the west and north, the 

 details of which have not yet been published in his work on 

 China. The red sandstone (Nos. 4 and 5) described by Miss 

 Fielde as a possible representative of the Ti'ias, is apparently a 

 member of the series referred by Richthofen to the Jurassic 

 period so identified by the plant remains. 



Chinese Rhizopods. Miss Fielde also announced that during 

 her study of the fresh-water Rhizopods found in the streams 

 around Swatow, she had collected several forms identical with 

 those described by Dr. Leidy, from the neighborhood of Phila- 

 delphia (Difflugia urceolata, D. pyriformis, Arcella vulgaris).
