292 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



except that they have thus far found none of the latter asso- 

 ciated with brackish -water forms. Geophila were obtained 

 from the Green River and Bridger Groups only. These com- 

 prise three or four genera of Helicedm. 



The Green River Group has furnished several species of 

 insects. 



Of vertebrate remains, some massive fragments of bones 

 of a very large saurian, found in Jurassic strata five miles 

 west of Vermilion Caiion, are worthy of remark. Scales and 

 detached bones of teliost fishes were found in considerable 

 abundance in dark shales at the very base of the Cretaceous 

 group at Vermilion Canon, and also at various other points 

 on the same horizon. Teliost fish remains, mostly very per- 

 fect, were obtained from the Green River Group, and also 

 some from other Tertiary strata. Throughout the whole 

 Tertiary series more or less vertebrate remains have been 

 found ; but it is the Bridger Group that has furnished the 

 greatest profusion of mammalian, besides many reptilian and 

 a few ganoid remains. 



Part of a skeleton of a Passerine bird has been obtained 

 from the Green River Group. 



Large collections of plants have been made at numerous 

 localities. Besides samples of silicified exogenous wood 

 from numerous horizons throughout the Mesozoic and Ter- 

 tiary series, leaves, fruits, etc., have been collected from the 

 upper Cretaceous and Tertiary strata. These are mostly 

 exogens, but both ferns and palms were found associated 

 with them in the upper Green River Group at Alkali Stage 

 Station, twenty miles northward from Green River City. 



Ethnography. Professor Thompson's party discovered the 

 ruins of many prehistoric dwellings similar to those found in 

 former years, and their position will be indicated on the eth- 

 nographic map. He also discovered on the caiion walls and 

 rock escarpments of the country many Shi-nu-mo etchings, 

 which were copied to scale. They will make a valuable ad- 

 dition to the collection of former years. 



While on his travels Major Powell met with certain tribes 

 of Shoshoni Indians, whose arts were unrepresented in the 

 National Museum, and the opportunity was seized upon to 

 make collections of their implements, clothing, etc. In all 

 departments, except that of food -plants, these Indians are
