 Helopora lineata, formosa, concava, strigosa, nodosa, lineopora, armata, bellula, 

 striatopora, irregularis, Circe, varipora.

* Prout, Hiram A. Descriptions of new species of Bryozoa. (Trans. 



St. Louis Acad. Sci., II, 1866, pp. 410-113.) 

 The species described are Fenestella nodosa, dilata, bifurcata, Polypora imbricata, 

 rigida, Eetepora hamiltonensis, Ptilodictya (Stictopora) variabilis. 



* Prout, Hiram A. Descriptions of Pol3^zoa from the Paleozoic rocks. 



(Geological Survey of Illinois, II, 1866, pp. 412-423, pis. xxi, 



xxii.) 



Gives descriptions with figures of Coscinium Wortheni, elegans, plumosum, Mich- 



elinia, saganella, tuberculatum, asteria, Cyclopora, C. fungia, discoidea, polymorpha, 



Polypora Halliana, gracilis, Hamiltonensis. These had all but the last previously 



appeared in the Trans. St. Louis Acad. Sci., I, 1860. 



*Rominger, Carl. Observations on Chtetetes and some related gen- 

 era, in regard to their systematic position, with an appended 

 description of some new species. (Proc. Acad. Nat. Sci. Phila- 

 delphia, 1866, pp. 113-123.) 

 After a general discussion descriptions are given of a number of species, including, 

 besides the Stellipora antheloidea Hall, Trematopora tubulosa Hall, Ceramopora 

 foliacea Hall, the following new species: Chietetes quadratus, decipiens, Callopora 

 missouriensis, Fistulipora neglecta, Halli, lunata, heiios, stellifera, sulcata, minuta, 

 acervulosa, spinulifera, Eriensis, utriculus, crassa, elegans, Spergenensis, flabellum, 

 trifolia, compressa, peculiaris. The descriptions are unaccompanied by figures, but 

 are usually sufficient for identification — a decided merit in a work of that date.
