9. On some Fossils /rom tlie Menevian Geoup. By J. W. Salter, 

 Esq., A.L.S., F.G.S., and H. Hicks, Esq. 



[The publication of this paper is postponed.] 



(Abstract.) 



The authors, after describing the localities and stratigraphical rela- 

 tions of the Menevian group, proceed to describe the following 

 species : — 



Paradoxides aurora, Salter, represented by a few imperfect heads, 

 unattached pleurae, (fee. Localities, Porth-y-rhaw and St. David's. 



P. Hicksii, Salter. This species presents a singularly interme- 

 diate character, reminding us equally of Paradoxides and Anapo- 

 lenus. 



Conocoryphe bufo, Hicks, represented by a few separate heads, and 

 one with six body-rings attached. Localities, Porth-y-rhaw and 

 St. David's. 



G. applanata, Salter. Young specimens show all the metamor- 

 phoses observed by Barrande. The characters of such genera as Ag- 

 nostus and Microdiscus are as clearly seen in the embryo of Cono- 

 coryphe as in the adult state of those genera. Localities, Porth-y- 

 rhaw, St. David's, Maentwrog, and Dolgelly. 



C (?) numerosa, Salter, Of this species, a part of the head and 

 six thoracic rings have been found. These, however, show charac- 

 ters sufficient to indicate that it is specifically, if not generically, dis- 

 tinct from the others. Localities, Porth-y-rhaw and St. David's. 



10. Report of recent Earthquakes in Northern Formosa. By 

 H. F. Holt, Esq., H.M. Consul at Tamsuy. 



[Communicated by the Secretary of State for Foreign Affairs.] 



(Abstract.) 



The first shock felt in the northern end of the island took place on 

 the morning of the 18th of December, 1867, and lasted about fifteen 

 seconds. Many buildings were destroyed, and many lives lost, in 

 Tamsuy. About fourteen minor shocks were felt during the same 

 day, and on the 20th another violent shock occurred. 



At Kelung the whole harbour was left dry for a few moments ; and 

 the water returning in one vast wave, rushed into the town itself. 

 Large landslips have taken place, and several villages between Ke- 

 lung and Tamsuy have been destroyed.
