Note. — A number of contributions have appeared during the progress of this report through the press, the results 

 of which can not be fully incorporated in the following pages, although footnotes concerning some of them have been 

 insetted. Among the more important of these publications are: 



Jackson, R. T., Phylogeny of the Echini, with a revision of Paleozoic species: Boston Soc. Nat. Hist. Mem., vol. 7, 

 491 pp., 76 pis., 258 figs., 1912. 



Jackson proposes the generic name Centrechinus to replace Diadema, thus changing the names of family and 

 order to which the genus belongs. 

 Smith, J. P., The Middle Triassic marine invertebrate faunas of North America: U. S. Geol. Survey Prof. Paper 83, 

 254 pp., 99 pis., 1914. 



Smith refers to Pentacrinus cf. P. asteriscus Meek and Hayden, in material from the Pit shale of California.
