family as thus limited extended from Upper Cambrian to Upper 

 Silurian times. The earliest known Graptolites were those of the 

 Skiddaw Slates, which he thought would prove to belong to the 

 Upper Cambrian series. The Skiddaw area he considered to extend 

 into Canada, where the Quebec group belongs to it. Genera of 

 Graptolites belonging to this area are represented in Australia ; and 

 this the author regarded as indicative of migration, but in which 

 direction was uncertain. Having discussed the forms of Graptolites 

 characteristic of tht; deposits in the Skiddaw-Quebec area, the author 

 proceeded to indicate the mode in which the family is represented 

 in the areas of deposition of the great Silurian series — namely, the 

 Llandeilo areas of Wales and Scotland, the Coniston area of the 

 North of England, the Gala area of South Scotland, the Hudson - 

 River area of North America, and the Saxon and Bohemian areas — 

 giving under each of these heads a list of species, with indications of 

 their probable derivation. — Proc. Geol. Soe. Feb. 1872. 



Notice of a neiv Netted Sponge (Meyerella) from the Philippines. 

 By Dr. J. E. Gray, F.R.S. &c. 



The British Museum has just received a very beautiful clavate 

 netted sponge, discovered in the Philippines by Dr. Adolf Bernhard 

 Meyer, which I have proposed to indicate as a new genus under the 

 name of !\[eyeeell\. 



Sponge simple, elongate, clavate, acute at the apex, at which are 

 placed several tufts of short cylindrical fibres. The body of the 

 sponge is elongate- fusiform, with longitudinal ridges irregularly dis- 

 posed, often inosculating together, leaving various-shaped deep con- 

 cavities on the surface. These ridges and the very numerous irre- 

 gularly shaped often confluent elevations in the concavities between 

 thera are furnished with various-shaped large oscules on the upper 

 surface. The sides of the ridges and the tops of the prominences are 

 all united by a very fine cobweb-like netted coat, formed of numerous 

 fibres, and pierced with an immense number of very minute exceed- 

 ingly close perforations. The stem cylindrical, thick, ending in a 

 thick cylindrical tuft of elongated glassy fibres, evidently anchor- 

 ing the sponge in the sand ; numerous cylindrical bunches of fibre 

 are to be seen through the substauce of the sponge extending 

 throughout the greater part of the length of the stem. Species : — 

 Meyerella elaviformis.

Additional Note on Osteocella septentrionalis. 

 By Dr. J. E. Gray, E.R.S. &c. 



I have been informed by Dr. Giinther that this species (see Ann. 

 *fe Mag. Nat. Hist. ser. 4, vol. ix. p. 405) is frequently found in Buz- 

 zard Inlet, near New Westminster, Eraser lliver, British Columbia, 

 which confirms my original supposition that it probably comes from 

 the west coast of America.
