tion for information concerning this, and some 

 other species in this intricate class, which are 

 found in that most northern part of Great Bri- 

 tain. 



Is not this the younger specimen of foUascens 

 described by Pallas ? 



29. Pulchella. Composed of fine reticulations, 

 smooth and soft in appearance, and gene- 

 rally compressed and broad.

This species is described to be extremely irre- 

 gular in shape, sometimes approaching to fan- 

 shaped, sometimes rather palmated or digitated, 

 its fibres are delicately reticulated : like the com- 

 mon officinal sponge in colour, it varies from pa- 

 lish-brown to yellowish or reddish brown ; from 

 which it is, however, readily distinguished by its 

 less coarse appearance ; and its texture may be 

 somewhat more rigid. 



Mr Sowerby, who first publicly noticed this 



sponge, received specimens from Ireland, and from 



the north of Wales. 



Professor Jameson remarks, that Dr Walker 



first noticed it on ^the shores of several of the 



Western Isles.
