GENERAL HISTORY. 27 



In the summer of 1878, Mr U. P. James commenced the 

 publication of a palseontological serial, entitled ' The Palaeon- 

 tologist,' of which, so far as I know, only four num- 

 bers appeared, the last being dated July 1879. In it 

 were given short descriptions of various fossils, unfortunately 

 not accompanied by any figures. Amongst these Mr James 

 described the following new species of MonticiUipora (referring 

 these to the genus Ch<^teles) : viz., C. ci'itsttilatus, C. Mceki, C. 

 varians, C. szibrotuiidiLs, and C mimttus. I have no means of 

 judging of the affinities of the three last of these ; but I have 

 examined the two species first mentioned, both macroscopically 

 and microscopically. The first of these i^M.? criistulata, James) 

 is certainly a new form, but I am not prepared to assert posi- 

 tively that it is a Monticiilipora, as it has some curious points 

 of resemblance to some of the types which are usually placed 

 under the genus Ceramopora, Hall. Of the latter, of which I 

 have ample material, I am able to say that the name of M. 

 Mceki, which Mr James only proposed provisionally, must be 

 abandoned, as it is a mere variety of the previously described 

 AI. gracilis, James. 



In 1878, Mr E. O. Ulrich published (Journ. Cincinnati Soc. 

 Nat. Hist., PI. IV. figs. 7, 7^) a description of a new species of 

 Alonticulipora, under the name of Chcstctes vemistus. 



In the following year (1879) the same excellent observer pub- 

 lished two further papers in the same Journal, in which 

 various species of Montictdipora and allied types were 

 described. In the first of these {loc. cii., PI. VII. figs. 25, 25^), 

 the author described a new species of MouticiLlipora under the 

 name of Chcctctes cojupressus, but the form is one with which 

 I am unacquainted. In the second paper in question (PI. XII. 

 figs. 9-12), entitled " Description of a New Genus and some 

 New Species of Bryozoans from the Cincinnati Group," Mr 

 Ulrich described as new species of Monticulipot'-a the follow- 

 ing types (placed under Chcctcics) : C. granuli/erus, C. irregu- 

 laris, C. sttbglobosus, and C. clcgaus. With regard to the first
