142 AMERICAN FOSSIL BRYOZOA. [bull. 173. 



Spencer, J. W. Niagara fossils. Part III. Fifteen new species of 



Niagara fossils. (Trans. St. Louis Acad. Sci., IV, 1881, pp. 602- 

 610, pis. vii-ix.) Also in (Bulletin of the Museum of the Univer- 

 sity of the State of Missouri, I, No. 1, 1881, pp. 52-61, pis. vii-ix). 

 Describes Rhinopora venosa n. sp., Clathropora? gracilis n. sp., Fenestella bicornis 

 n. sp., Polypora (Fenestella?) Albionensis n. sp. The fossils themselves are very 

 poorly preserved, the descriptions given are inadequate, and the illustrations are 

 almost worthless. It is doubtful if any can be recognized. The first two are almost 

 certainly synonyms for other species. 



1885. 



Davis, William J. Kentucky fossil Corals. Part II, 1885. (Kentucky 

 Geological Survey, John R. Proctor, director.) 139 pis., no text. 



Of this work only the plates have appeared. In the explanation sheets of plates 

 51, 73, 78, and 80 occurs a new generic term, Nicholsonia, with three species — cana- 

 densis (= Hederella canadensis (Nicholson)), adnata, and angulata. The last is not 

 a bryozoan nor even a fossil, while the second, though too poorly figured to be 

 determined with certainty, is probably the same as Hederalla filiformis (Billings). 



* Hall, James. On the mode of growth and relations of the Fenestell idse, 



(Report of the State Geologist of New York for the year 1884, 



Albany, 1885, pp. 35-46, pis. i, ii.) 

 The author defines various genera referred to the Fenestellidse and gives two plates 

 to illustrate generic structure. The work was in large part later incorporated in the 

 Paleontology of New York, YI, 1887. New genera, mostly called subgenera by the 

 author, are Fenestrellina [d'Orbigny?], Fenestropora, Ptyloporina, Ptyloporella, 

 Unitrypa, Isotrypa. 



* Nicholson, H. AUeyne, and Foord, Arthur H. On the genus Fistu- 



lipora M'Coy, with descriptions of several species. (Ann. Mag. 

 Nat. Hist., ser. 5, XVI, 1885, pp. 496-517, pis. xv-xviii.) 



An admirable study of the genus Fistulipora and a number of its species. The 

 structure of a number of previously recorded species is well worked out and the fol- 

 lowing new species fully described: Fistulipora muscosa (Lower Carboniferous — 

 Scotland), nummilina (Wenlock — England), dobunica (Wenlock — England), corna- 

 vica (Wenlock — England). American species described are F. utri cuius Rominger, 

 eriensis Rominger. 



1886. 



*Hall, James. Bryozoa of the Upper Helderberg group. Plates and 

 explanations. (Fifth Ann. Rep. State Geologist, New York, for 

 the year 1885, Albany, 1886, 14 pis.) Twelve plates bound in 

 quarto form were sent out in 1886 under the above title in brochure 

 form. 

 These plates appeared subsequently in the Paleontology of New York, YI, 1887. 



Ringueberg, Eugene N. S. New genera and species of fossils from the 



Niagara shales. (Bulletin Buffalo Soc. Nat. Sci., V, 1886, pp. 5- 



22, pis. i, ii.) 

 Describes the following new species: Ceramopora orbiculata, Rhinopora curvata, 

 Stomatopora recta, parva, Chsetetes expansus. The illustrations are very poor.
