3. " On a new Genus of Siliceous Sponges from the Lower Cal- 

 careous Grit of Yorkshire." By Dr. G. J. Hinde, F.G.S. 



The following specimens were exhibited : — 



Specimens and microscopic sections of RJiaxella perforata, ISinde^ 

 gen. et sp. nov.,from the Lower Calcareous Grit of Scarborough (the 

 specimens belonging to the Natural-History Museums of York and 

 Scarborough), exhibited by Dr. G. J. Hinde, F.G.S., in illustration 

 of his paper. 



Specimens of Herpetocy^iniis Fletclieri^ Salter, from the Wenlock 

 .Limestone of Dudley, exhibited by P. A. leather, Esq., E.G.S. 



With regard to these specimens Mr. Bather said that Herpeto- 

 crinus of Salter { = Mydodaciylus, Hall) was described in Cat. Eoss. 

 "Woodwardian Mus. as possessing a coiled cirriferous stem, and 

 a small crown with dichotomous arms. American authorities, 

 however, had maintained Hall's view that the coiled structure was 

 an arm with pinnules. The two specimens belonging to Mr. E. 

 Hollier, of Dudley, which were on the table, conclusively proved 

 the correctness of Salter's position ; one of them was very fine, and 

 showed the structure of the dorsal cup. A specimen in the British 

 Museum had quite recently been discovered to possess a crown. 

 The drawings of stem-ossicles and of sections exhibited showed 

 that there were strong muscles on the outer curvature of the stem, 

 which could uncoil it.
