Reviews — Brief Notices. 379 



year cannot be included in the report for 1914. A considerable amount 

 of work has been done within the year, in spite of the serious hindrance 

 to development due to the lack of cases and room. In addition 

 to arranging and classifying the present collections and additions 

 received during the year, much of Mr. Macgregor's time has been 

 absorbed in making determinations for the public. Fifty-seven such 

 determinations were carried out, including twenty-three rock-slides, 

 besides a number of determinations at sight. Two collecting trips were 

 made by Mr. Macgregor — one to Shiloh, for the purpose of searching 

 for fossils of the Forest Sandstone formation, the other to theBembesi 

 Diamond Field and Somabula and Victoria districts. Although no 

 success attended the first of these journeys, the second resulted in the 

 acquisition of many valuable mineral and rock specimens. 



8. Anticosti Island. — This island consists of a part of a cuesta on 

 an ancient coastal plain which probably began to develop in the 

 Devonian and existed until the time of the post-glacial submergence. 

 It will be called the Anticosti cuesta. About 20 miles to the north 

 the Mingan Islands fringe the Quebec shore and consist of the 

 remnants of a parallel cuesta. This will be named the Mingan 

 cuesta. Between the two cuestas lay an inner lowland which near 

 the west end of Anticosti was crossed by a north-south divide from 

 which streams drained east and west, the former being the larger. 

 North of the Mingan cuesta is another lowland. The latter will be 

 called the Laurentide lowland and the former the Channel lowland. 

 In these words Mr. Twenhofel (Canada, Dept. Mines, Mus. Bull., 

 No. 3, 1914) describes the structure of Anticosti Island, and then 

 proceeds to give faunal summaries of the various formations for the 

 Ordovician and Silurian systems. He describes a few new species 

 of fossils, and promises an exhaustive memoir on the geology and 

 palaeontology later. 



9. Leeds. — The activity of the Leeds Geological Association may 

 be gathered from the last number of the Transactions (part xvii, 

 191 1—13. November, 1914). Miss S. E. Chapman writes on "Some 

 Petrological Characteristics of Underclays " ; Mr. C. Thompson, 

 "Ammonites of the Lias"; P. F. Kendall, "Evidences of Climatic 

 Changes in Geological Times"; Burnet & Everett, "Sections in 

 a Quarry at Robin Hood, near Leeds ", in the Middle Coal-measures. 

 Many excellent photographs and quite a good list of plants accompany 

 this last paper. 



/^10. Beatricea. — This very old friend and puzzle to the palaeonto- 

 logist has turned up in the Middle Ordovician of South Pennsylvania. 

 It was first noticed there by TJlrich in 1908, and P. E. Raymond has 

 seen the specimens and described them in detail in Canada, Dept. 

 Mines, Mus. Bull., No. 5, 1914. Raymond gives very fine photographic 

 sections, and though he inclines to the Stromatoporoid view of their 

 relationships he cautiously refers to them as "early Palaeozoic 

 organisms". Moreover, he does not consider that TJlrich's specimens 

 are true Beatricea, and proposes for them the new generic and 

 specific name of Cryptophragmus antiguatus. Mr. Raymond has 

 done good service in presenting us with such excellent figures 

 for study.
