writer found a few scarcely determinable fossils, among 

 them a Halobia resembling H. suferha, which is common 

 in the Karnic beds of Shasta County, California. 



Above the Star Peak limestone there is a series of shales 

 and shaly limestones aggregating about eight hundred feet 

 in thickness. These are best exposed in the Muttleberry 

 Mountains, in Muttleberry Canon, about eight miles south- 

 east of Lovelock, Nevada.^ At this locaHty the writer found 

 Arcestes sp. nov., Rhabdoceras 7'iisselli Hyatt, Placites sp. 

 indet., Halorites sp. indet., and Pseudoinonotissuh circular is, 

 the last very abundant. 



These beds are overlain uncomformably by impure lime- 

 stones of the Lower Jura, or Lias, with Arietites (Calo- 

 ceras) conf. nodotiamis d'Orbigny. It is therefore more 

 than a probabihty that the Star Peak limestone corresponds 

 in part, at least, to the Hosselkus limestone of the Upper 

 Trias of California, and that in both regions the Pseudo- 

 monotis beds mark the highest horizon of the marine Trias. 



The Uffer Trias of British Columbia and Alaska. The 

 Geological Survey of Canada has discovered Triassic fos- 

 sils at a number of localities in western British Columbia, 

 Stikine River, Peace River, Nicola Lake, Liard River, 

 about twenty-five miles below Devil's Portage, lat. 59° 16' 

 N., long. 125° 35' W., Vancouver Island, and Queen Char- 

 lotte Islands. Most of the fossils known from that region 

 came from the two last localities, and they all seem to belong 

 to the Upper Trias; but it is not likely that they all came 

 from the same horizon, for Halobia lommeli belongs to the 

 Longobardic substage, while Pseudomonotis subcircularis 

 Gabb belongs to the Noric stage, and both are cited from 

 Queen Charlotte Islands, along with Acrochordiceras? 

 carlottense Whiteaves, Arniotites vancouverensis Whiteaves, 

 Badiotites ? carlottensis Whiteaves, Arcestes gabbi Meek, 

 and Aiilacoceras carlottense Whiteaves. From the Liard 

 River locality are listed : Halobia lommeli Wissmann, H. 

 occidentalis Whiteaves, Monotis ovalis Whiteaves, Trigono- 



iThe writer is indebted to Mr. Frank M. Anderson of Berkeley, California, for the dis- 

 covery of this locality.
