which indicate the existence of a ventral plate in this genus. The 

 evidence in favour of this interpretation is given at length, and the 

 fossil originally described as P. hitnmcata is maintained to be the 

 Scaphaspid plate of F. americana. 



The existence of lateral plates and of lateral organs (' fins ') is 

 also discussed, and a comparison made between Pakeaspis and other 

 Pteraspids. The Author attempts a restoration of Palceaspis, and 

 gives an amended definition of the genus. 



4. " Notes on some New and Little-known Species of Carboni- 

 ferous MarcJiisonia." By Miss Jane Donald. 



In a previous paper, the various sections into which it has been 

 considered advisable to group different species of Aliirchisonia have 

 been noticed. Of the species described in the present communi- 

 cation, two only can be undoubtedly referred to Goniostropha of 

 (Ehlert. Others have the sinus situate above the angle ; and if this 

 ])osition of the sinual band be considered sufficiently distinctive, the 

 Authoress suggests the name fft/pergonia for this section, and takes 

 MurcMsonia quadricannata as the type. 



The following new forms are described: — Murcliisonia {Gonio- 

 stro_pha) hibernica, M. {G.) Tatei, M.{Hypergonia) quinquecarinata, 

 De Kon., var, jJulcheUa, M. (B.) conula, De Kon., var. convexa, 

 M. (H.) pentoiiensis, M. (H.) Kh-Tchyi, M. {H.) plana, M. {Coda- 

 caxdus^.^ tuedia. 



A fuller description is also given of a species previously described 

 by Prof. Haughton under the name of Cerithoides telescopium. 



5. "Microzoa from the Phosphatic Chalk of Taplow." By F. 

 Chapman, Esq., F.R.M.S. 



Ninety-eight species and varieties of foraminifera, and five species 

 and varieties of ostracoda have been found in this deposit. All the 

 forms of ostracoda have been previously found in the Chalk. Of 

 the 98 varieties of foraminifera 5 ajipear to be new, whilst alto- 

 gether 30 are new to the Chalk fauna. 



The following new forms are described: — Nahecxdaria Jonesiana,

Additional Note on the Occurrence of Lichia vadigo on the Oornish 

 Coast. By Dr. A. Gunther, F.R.S. 



In the Ann. & Mag. Nat. Hist. 1889, iii. p. 107, I reported the 

 capture of a specimen of Lichia vadigo off the Isle of Skye, noticing 

 it again in the Proc. Zool. Soc. 188U, p. 50, and accompanying that 

 note with a figure of the fish. I have now the pleasure of 

 recording the capture of a second specimen on the south-west coast
