144 AMERICAN FOSSIL BRYOZOA. [bull. 173. 



* Hall, James, and Simpson, G-eorge B. Paleontology of New York, 



VI, Corals and Bryozoa : Text and plates containing descriptions 



and figures of species from the Lower Helderberg, Upper Helder- 



berg and Hamilton groups. Albany, 1887. xxvi, 298 pp., 67 pis. 



It is to be regretted that this, the most important work of the New York Survey 



upon the bryozoa, should prove on critical examination to be of so little value either 



to the systematist or to the practical paleontologist. As Hall acknowledges that the 



work was practically done by the draftsman, Mr. George B. Simpson, the merits 



and demerits of the volume may be prpperly charged to the latter. The drawings, 



however beautiful, are diagrammatic to an extreme and are of little assistance to the 



student. The descriptions are in many cases vague, and often differ so decidedly from 



previous descriptions of the same form that no reliance can be placed upon them. 



The great number of forms distinguished is confusing. Synonyms, we believe, 



abound. ( See note under Lioclema minutum in the Catalogue of Genera and Species. 



The bryozoa of New York still require study. 



Brief generic diagnoses of the genera and subgenera used, 60 in number, are 

 given in the preliminary pages, prepared by Mr. Charles E. Beecher. Descriptions 

 follow of 83 species and 3 named varieties from the Lower Helderlierg, 153 species 

 and fi named varieties from the Upper Helderberg (a large number of these are from 

 the Falls of the Ohio and are now considered by Ulrich of Hamilton age), and 113 

 species from the Hamilton. A few species (one from the Niagara) have crept into 

 the plates without description.

of the Cincinnati group, with a critical revision of the species. 



(Jour. Cincinnati Soc. Nat. Hist., X,1887, pp. 118-141; X, 1888, 



pp. 158-184; XI, 1888, pp. 15-47. 



The title is sufhciently explanatory of these papers, which are iconoclastic inspirit 



and decry modern methods of research. A few species described by Mr. U. P. James 



are wretchedly illustrated.

 Acad. Nat. Sci. Philadelphia, 1887, p. 11, pi. i.) 

 Gives a description of the exterior appearance of three specimens of a new bryo- 

 zoan discovered in Corniferous drift bowlders of Michigan for which the new generic 

 and specific name Patellipora stellata is proposed.
