 This paper is devoted to the bryozoan fauna of the Lower Helderberg group. 

 Descriptions only are given. Figures and fuller descriptions are later given in the 

 Paleontology of New York, VI. Thirty-four new species are described, referred to 

 the genera Fenestella, Polypora, Hemitrypa, Ichthyorachis, Escharopora, Callopora, 

 Treniatopora, Ceramopora, Chastetes, and Paleschara, the last a new genus whose 

 systematic position is still somewhat doubtful.

Chsetetes. - (Cincinnati Quarterly Journal of Science, 1, 1874, 



pp. 368-375.) 

 After a general discussion the writer gives descriptions of Stenopora Lonsdale, 

 Stenopora fibrosa Goldfuss 1826 from Lexington, Kentucky, Stenopora lycoperdon 

 Say, Chsetetes Fischer, Chfetetes petropolitanus (Pander). These are all incorrect 

 identifications.

Paleontolog}^ of the Province of Ontario, with brief descriptions 

 of some new genera. (Canadian Journal, new ser., XIV, 1871, 



pp. 125-136.) 

 The new genera Cryptopora, Carinopora, Tgeniopora, and Botryllopora are 

 described. 



* Nicholson, H. AUeyne. Descriptions of two new genera and species 



of Polyzoa from the Devonian rocks. (Ann. Mag. Nat. Hist., 



ser. 1,"XI1I, 1871, pp. 77-85.) 

 The author describes Cryptopora n. g. with the new species C. mirabilis and Cari- 

 nopora n. g. with the species Hindei n. sp. Both genera have proved untenable, 

 being founded upon imperfect material in a peculiar state of preservation.
