of Temminck's Manual ; and a new species of Phaleris^ Temm. 

 The Prince of Musignano made some observations on these birds, 

 and signified his intention of describing them in the Zoological 

 Journal, in a supplementary paper to his '^Synopsis''' of the 

 birds of the United States. He proposed to call tlie new species 

 of Phalerisy P. cerorhynca.^ 



GEOLOGICAL SOCIETY. 



May 5, 1826. The reading of a paper, by Dr. Bigsby, On the 

 Geology of the Valley of the St. Lawrence^ was concluded. 



June 2. A paper was read, entitled, On the fresh-water strata 

 of Ilordwell^ Beacon^ and Barton Cliffs^ Hants. ; by C. Lyell, 

 Esq. F.R.S. F.L.S. F.G.S. 



Nov. 3. A paper was read, entitled, Additional remarks on 

 the nature and character of the Limestone and Slate^ principally 

 composing the rocks and hills round Plymouth ; by the Rev. R. 

 Hennah, F.G.S. The authour refers to a former paper on this 

 subject, in which he confined his field of observation to the narrow 

 tract between the Plym and the Tamar ; he now extends its limits 

 to Mount Batten and Statten heights, in a southerly direction. 

 In this tract, which forms the eastern side of Plymouth Sound, as 

 well as the western side from Mount Edgcumbe to Pudding Point, 

 animal-remains are imbedded in the slate. On the eastern side 

 the superior beds are occasionally of an ochreous clay slate, con- 

 taining thin ferruginous veins with trochites and stems of encri- 

 nites : these are associated with some other fossil remains, the ' 

 characters of which are indistinct. The lower beds consist of 

 compact light gray slate inclosing remains like those found in the 

 limestone and clay-slate. An ironstone bed occurs here which 

 is used for pavements ; and fragments of animal-relics are disco- 

 verable in it. From these facts the authour infers, that the slate 

 which is prolonged beyond the Plymouth limestone, even as far 

 southward as Whitesand Bay, is not primitive : but he remarks, 

 that he has never perceived animal-remains in the slate north of 

 that limestone.
