cerviue species, are now re]3resented in south-eastern Asia and the 

 Sunda islands. The occurrence of these animals in tropical countries 

 at the present day does not, however, necessarily imply a tropical 

 climate iu Pliocene Italy. Some instances in modern geographical 

 distribution are quoted in illustration of this ojjinion. It is probable 

 that the Pliocene fauna of Europe extended as far as Celebes, and 

 has been preserved in the Indian archi])elago by isolation. 



In conclusion it was shown that the preservation of a Miocene form; 

 Mi/ohu/us surdonis, iu the Pleistocene bone-brecciaa of Corsica and 

 Sardinia, and the occurrence of Eleplias meridionalis and Mastodon 

 arverneiisis in beds of different age on opposite sides of the Alps, are 

 instances in support of the view that a single mammalian species or 

 even a few species cannot be sufficient to determine the age of 

 beds. 



In a note appended to the paper. Prof. Boyd Dawkins contested 

 the opinion that no species pass from Miocene to Pleistocene beds, 

 especially in the case of Hippopotq,mus major of the former and 

 H. amphibius of the latter, 



9. " Xotes on some Cretaceous Lichenoporidae." By G. R. Vine, 

 Esq. Communicated by Prof. P. Martin Duncan, F.E.S., E.G.S. 



In this paper the author referred to the views of Mr. Hincks on 

 the genera belonging to the family Lichenoporidae, and especially to 

 his suppression of the genus Radiopora of D'Orbigny, the species of 

 which are placed by Mr. Hincks in the genus Lichenopora. The 

 author remarked that the type species of the division of the latter 

 genus identified by Mr. Hincks with Radiopora^ D'Orb., the Lower 

 Greensand Radiopora pustulosa, D'Orb., and other fossil species show 

 structural peculiarities which would seem to distinguish them, 

 although perhaps not generically. He described in some detail the 

 characters of the above-mentioned species under the name of LicJieno- 

 pora p>ustidosa ; and further described what he believed to be a new 

 species from the Greensand of an unknown locality under that of 

 Lichenopora paucipora.

On Paludicella erecta. 

 Mk. Edwarr Poits desired to have a preliminary record made of 

 his recent discovery or identification of a new species of Paludicella 

 for which he proposes the name of Paludicelhi erecta. 



This genus of freshwater Polyzoa has heretofore contained only 

 the single clearly defined species P. Ehrenhergi, Van Beneden 

 {Alcyonella articulata, Ehrenberg), the other two names, P. pro- 

 cumhens and P. elougata, suggested by Mr. Albany Hancock and 

 Prof. Leidy, being considered by Prof. Allman as identical with the 

 original type. The present form is strikingly diftereut from the old 

 one, both in the number of its ciliated tentacles and in the character 

 of the coeuoecial cells. The doubt which has lingered in the mind
