were well preserved ; otherwise the beautifully crenulated wall surround- 

 in^ the orifice was sufficiently indicative of the normal type. 



°In the ' Catalogue of Tertiary Fossils in the School of Mines (18/8), 

 the only species indicated from different horizons are as follows :—

6 ',', crassa, „ London Clay, Highgate, p. 14. 



7. Poiazoon, „ ,, Sydenham, p. 14. 



In Morris' ' Catalogue of British Fossils,' and also in the Palaeon- 

 tological part of Jukes' ' Students' Manual of Geology,' the following 

 species are indicated : — 



8 Eschara Brongniaeti, Lonsd., London Clay, Bracklesham Bay. 



9. Flustra ceassa, Desm., „ „ Primrose Hill. 



10. Cellepora petiolus, Lonsd., Mid-Eocene, Bracklesham.

= Coscinoporis pileolus, Phill. and Wood. 

 - 12. Idjionea coroxofls, Defr., Mid-Eocene, Bracklesham Bay. 



Besides the above I have no further record, but I have some few 

 fragments by me of undescribed forms from the Middle Eocene, British 

 series It may be possible that there are still in the cabinets of collectors 

 specimens of Polyzoa that are awaiting description ; if so, I shall be glad 

 to hear of such. 



' Tertiary, Eocene and Miocene Polyzoa,' Professor A. E. Reuss. 



I In dealing with the following three works of Dr. Reuss I have 

 been' careful to present his text with his own indications of synonymy. 

 In the earlier work, published in 1847, the author described and figured 

 no fewer than 120 species of Cheilostomata aud 49 species of Cyclosto- 

 mata This work of course was published before Mr. George Bask issued 

 bis ' British Museum Catalogue,' and also before Professor Smitt gave 

 to the scientific world his principal writings on ' Classification, &c. ; yet 

 in it we are surprised to find how this careful investigator was working 

 towards a natural classification. ,„„„„. -d i a +i 



II In the second work, published in 18b9, Professor Reuss had the 

 advantage of correcting much of his previous labours, and m the ' Palav 

 ontological Studies' many of the species of < Fossil Polyparia were re- 

 duced to synonyms. In this work, too, Reuss evident y had carefully 

 studied both the classification formulated in the ' British Museum Cata- 

 logue ' and also the ' Crag Polyzoa ' of Mr. Busk. Nearly every species 

 described in this work I have carefully studied from the material supplied 

 by Professor Roemer. . 



III In the third work— ' Miocene Fossil Bryozoa of Austria and 

 Hungary ' 1884-5, which the author did not live to complete— we have 

 such°a piece of work of which no author who has taken up the study of 

 Fossil Polyzoa need to be ashamed. In this we have full revisions of former 

 identifications— more species are reduced to synonyms— but, what I regret 

 most the Cyclostomata are not touched. Dr. Manzoni completed the 

 second part of this grand work, but, as would be expected, he did not 

 give so many synonyms as Reuss would have done, had the work lett his 

 hands in a complete form.
