 This jmblication, designed as a serial, ended with its first number. The author 

 discusses (.'ritically the families Fenestellidee and Acanthocladiidji3 and diagnoses their 

 {jenera. Two m-w <:enera are defined, Buskoj)ora and Lichenotrypa, and sixteen new 

 sjiecies from the Falls oi the Ohio, referred to the genera Fenestella, Semicoscinium, 

 Unitrypa, Polypora, Fistulipora, Eridopora, Buskopora, Lichenotrypa, and Discotrypa.

 nary descriptions of some of the new species. (Fourteenth Ann. 

 Rep. Geol. Nat. Hist. Sur. Minnesota, 1886, pp. 57-103.) 

 One new genus is established, Honiotrypella, and 37 new species descril)ed from 



the Trenton strata of Minnesota, which are later fully described and figured in 



Geology of Minnesota, III. 



1887.

tific Laboratories of the Denison University, II, 1887, pp. 71-88, 



pi. vii.) 

 This paper, following the lines of work laid down by Mr. Ulrich, deals fairly well 

 with the Coal Measures fauna of Flint Ridge in central Ohio. One new genus, 

 Chainodictyon, is proposed, and the following new species are described : Rhombo- 

 l)ora multipora, Glanconome whitii, Chainodictyon laxum, Fenestella limbatus and 

 var. remotus, Stenopora Ohioensis. 



* Foerste, August F. The Clinton group of Ohio, Part III. (Bulle- 



tin of the Scientific Laboratories of the Denison University, II, 

 1887, pp. 119-176, pis. xv-xvii.) [The plates were, however, 

 omitted from this volume, but pis. xv and xvi appear in the suc- 

 ceeding volume, III, 1888.] 

 This paper contains the best account which has yet appeared of the bryozoan faiina 

 of the Clinton group in Ohio. The new species are Hemitrypa ulrichi, Pachydictya 

 emaciata, bifurcata-instabilis, turgida, obesa, Prasopora parmula, Monotrypella con- 

 fiuens, Callopora magnopora, Ohioensis.

 ence, XI, 1888, p. 22.) 

 These two articles, written in reply to earlier communications in Science by Joseph 

 F. James decrying the newer methods of investigating Paleozoic bryozoa, set forth 

 admirably the spirit and method of modern studies on the Paleozoic bryozoa.

Contains descriptions of twenty-tw^o species of Fenestella, of which four are called 

 n. sp., from the Hamilton group, illustrate<l by thirteen plates, of whi(;h seven appear
