GEOLOGY. 369 



Dr. Marshall A. Howe, of the New York Botanical Garden, has 

 completed his manuscript on the calcareous algse. One new species 

 of Archosolithothamnium from Antigua is most nearly related to a living 

 species from Sulu Archipelago, Borneo, and Celebes, while another 

 species from Antigua, though probably distinct specifically, is appar- 

 ently related to Lithothamnium vaughani from the Ohgocene of the 

 Panama Canal Zone. 



Professor E. W. Berry, of Johns Hopkins University and of the 

 U. S. Geological Survey, reports that he has recognized in Antiguan fossil 

 woods several forms which also occur on the Isthmus of Panama. 

 They are sufficient to indicate an Ohgocene age, and when the large 

 collections of similar remains from the Ohgocene Catahoula and Vicks- 

 burg formations of the southern United States have been studied it 

 may be possible to make some definite correlations. This statement 

 is based on a prehminary examination of the material. 



Dr. Joseph A. Cushman, of the U. S. Geological Survey, who has 

 completed monographs of the Pliocene and Miocene foraminifera of 

 the Coastal Plain of the United States and of all the fossil foraminifera 

 contained in the collections from the Canal Zone, is studying the fossil 

 foraminifera of the West Indies. He is at present engaged on a mono- 

 graph of the genus Orhitoides, which is largely represented in the upper 

 Eocene and Ohgocene deposits of the southern United States, Central 

 America, and the West Indies. As soon as practicable, in addition to 

 the one on Orhitoides, he will submit a general report on the other fossil 

 foraminifera from the West Indies. The collections have already been 

 sorted according to the different species. 



Previous to my expedition, I had described and figured, with very 

 few exceptions, all known fossil West Indian corals. The additional 

 material has been prepared and sorted into species, and most of those 

 already described have been identified. A few months wiU suffice to 

 incorporate descriptions of the new material in my manuscript and to 

 have the monograph ready for press. Deductions as to the geologic 

 ages indicated by these organisms were published in the Year Book for 

 1914, pp. 359-360, and other notes appeared in the Journal of the Wash- 

 ington Academy of Sciences.^ 



Dr. R. T. Jackson has identified the fossil echinoids collected in 

 Antigua, St. Bartholomew, and Anguilla, and has in preparation a gen- 

 eral report on the fossil echinoids of the West Indies and Central Amer- 

 ica. Photographic illustrations of the types of the species described 

 by Guppy and Cotteau from the Lesser Antilles, all of which are the 

 property of the U. S. National Museum, have been made. It was 

 noted in the last Year Book, p. 360, that Echinolampas semiorbis Guppy 

 is conmion to the Emperador limestone, Panama, and to the argilla- 

 ceous hmestone of Anguilla. The type is from the latter locahty.
