98 BRITISH SPONGES: 



Solander should be quoted as a synonyme of Sj). murir.ata in 

 the second edition of Lamarck's great work. 



Esper's Spongia stuposa, tab. 40, is also different from 

 our spong-e. It is said by Lamarck to represent Sp. tupha. 



The Spongia digitata of Templeton in Mag. Nat. Hist. 

 ix. 470, is founded on an old and injured state of Antennula- 

 ria antennina. 



4. H. hispida, " loith long, slender, round dichotomous 

 branches, covered with stiff hairs;'''' " spicula linear, coarse, 

 and obtusely pointed." 



Spongia hispida, Montagu in Wern. Mem. ii. 86, pi. 5, fig. 1, 2. 

 Tupha hispida, Gray, Br. PI. i. 355. 

 Halichondria hispida, Flem. Br. Anim. 522. 



Hab. Coast of Devon, rare, Montagu. 



" This slender branched sponge appears as if it sometimes 

 grew horizontally on each side fi'om the point of adhesion, 

 which is very slight ; in this case, both ends become branched. 

 Others rise perpendicular from the base, which is attached to 

 old shells ; in some instances several stalks originate from the 

 same spreading base, but are rarely connected : the branches 

 are nearly round, except where they divaricate. Three, and 

 sometimes four subdivisions take place in the larger specimens ; 

 the points of the subdivisions are subacute. Length, a foot or 



more. When recent, contains a great deal of gelatinous flesh, 



and is of a yellowish-brown colour, becoming darker as it dries. 

 The only specimens that have occurred, were taken off the coast 

 of Devon by the trawl ; rare. 



" The description given of *S'. tupha would tolerably well 

 accord with this, had not that species been stated to be soft, 

 whereas this is hard, and not composed of so fine a texture as 

 S. oculata, and is thickly muricated with hairs." Montagu.
