Prof. H. Alleyne Nicholson ha« made one new genus for the corals 

 of this Group and described nineteen new species. The new genus 

 Columnopora includes but one species. The now species are as follows: 

 Columnopora cribriformis, Chetetes appro.thnatus, C. attritus C. snbpid- 

 ehelbis, C. gracilig, C. delicatuhi^, C. noduhsus, C. Jamm, C. rhombicua, 

 C. briareus, C. sigillaroides, C. discoidcm, C. chthratidu>i, C. corticans, 

 C. Ortoiii, C. Neivberryi, C. petechialis, Constellaria polystomella and 

 Pheophyllum divaricam. Of these, four species had been pointed out 

 and named by Mr. James, and one, attritus, we have elsewhere shown 

 to be, probably, merely a peculiarly worn form of Monticidipora fibrosa. 

 The reason given by Prof. Nicholson for using Chetetes instead of Mon- 

 tieaUpora does not seem to have been very convincing to himself and we 

 have no doubt, Avill be sufficient to convince nearly every one, that if 

 such is the best argument, that can be adduced in favor of c;illing our 

 corals Chetetes, the sooner it is wliolly abandoned and J/ouiicu//'jpyra sub- 

 stituted the better it will be for our nomenclature. 



Mr. Aug. R. Grote and W. H. Pitt of Buffalo, New York, have 

 described a new Crustacean, from the water-lime group, allied to the 

 Eurypterm, for which, they have proposed the name Eusarctis Seor- 

 pionis. 



Prof. James Hall, of Albany, New York, has disposed of his large 

 and unequalled collection of fossils, to the Central Park Museum of 

 New York city. It is reported that the sale was effected in considera- 

 tion of sixtv-five thousand dollars. 



OBITUARY. 



Sir William Logan, the distinguished Geologist, died at London, in 

 June last, in his TDtli year. Ho was at the head of the Geological 

 Survey of Canada from 1843 to 1871, and his work is an everliving 

 monument of original investigation, extreme care, and profomn 

 knowledge of Stratigraphical Geology. He never dealt in far fetched 

 suppositions, and extravagant theories, but sought the facts, and ilem- 

 onstrated his discoveries, in the plainest, most forcible and clear langu- 

 age to be found, in American Geological Reports. 



G. P. Deshaves, the distinguished paleontologist, died, at Paris, on 

 the 9th of June last, in his 79th year. 



Dr. L A Laphain of Milwaukee, Wisconsin, died on the 14th of 

 September. He was best known for his labors in arclurology though 

 he was also a good geologist. He wrote up the^ Monnd-builders 

 of his State under the title of "Antiquities of Wisconsni, which 

 was published, with numerous plates and illustrations, by the bmitu- 

 sonian Institution.
