Cromer, but both there and at Mundesley the associated testacea all 

 belong to living freshwater species ; even the Paludina minuta (Strick- 

 land), which Mr. Morris has pointed out to the author to be iden- 

 tical with the P. marginata of Michaud, a living French species. 

 It is a question therefore, the author states, whether these unknown 

 fishes may not still inhabit the rivers and lakes of the more northern 

 parts of Europe or America, especially as M. Agassiz is at present 

 unacquainted with the freshwater fishes of Norway, Sweden, Spitz- 

 bergen, Iceland, Greenland, Labrador and Canada, and even of the 

 northernmost parts of Scotland and the Shetland Islands ; and in 

 conclusion Mr. Lyell says, it seems natural to look northward for 

 types analogous to the Mundesley fishes, because the beds in which 

 they occur were deposited contemporaneously with the drift accu- 

 mulated by the agency of floating ice.

Nov. 24, 1840. — William Yarrell, Esq., Vice-President, in the Chair. 



A paper by W. J. Broderip, Esq., was read, in which the author 

 proceeds with his descriptions of the new species of shells collected 

 in the Philippine islands by H. Cuming, Esq. 



Helix (Cochlostyla) Ticaontca. Hel. testa subpyramidali, trun- 

 catd, anfractibus 5 ventricosis, ultimo longe maximo, apice sub- 

 complanato, lineis incrementi subobliquis, levissime striato; aper- 

 turd modicd. 

 Var. a. Brunnea, strigis oblique longitudinalibus latis albis picta; 



apice subpurpureo ; aperturd albidd ; labii limbo subpurpureo. 

 Var. b. Brunnea, strigis oblique longitudinalibus albis creberrimis 



fucata; fascid basali latd obscurd; labii limbo subpurpureo. 

 In this variety the broad white stripes of the body- whorl are so 

 frequent, that they run into each other, leaving only brown inter- 

 stices here and there. 



Var. c. Brunneo -nigricans, strigis latis et maculis irregularibus albis 



rarioribus ornatis; labii limbo subpurpureo. 

 In this variety, the stripes, so far as they go, are very distinct ; 

 but on the last part of the body- whorl they are broken up and inter- 

 rupted so as to form spots. The ground-colour of the body- whorl 

 is very dark chestnut-brown, with a darker, but very obscure, broad 

 basal band. 



Var. d. Flavescens strigis albis fucata, fascid latd basali brunneo- 



nigricante ; labii limbo purpureo-nigricante . 

 Var. e. Ex albido flavescens seu subvirescens ; anfractibus 2 ultimis 

 strigis latis albis ornata ; anfractu basali lineis transversis basa- 

 libus interruptis subobscuris vittato ; aperturd albd ; labii limbo 

 ochraceo-rubro ; apice roseo. 

 Var. /. Ex albido flavescens seu virescens; anfractu ultimo strigis 

 latis albis interdum subangulatis ornato ; fascid basali brunneo- 

 lineatd, latd ; aperturd albd ; labii limbo vix ochraceo-rubescens.
