H. ?nacularis. (See Dr. Johnston, in Bei'w. Club Proc, vol. ii. p. 196.) 



This sponge incrusts the inside of an old valve of Pecten opercularis 

 dredged in Strangford Lough. 



When dredging in Strangford Lough on the 22nd of June, 1846, with 

 Mr. Hyndman, we were singularly fortunate in the number of sponges ob- 

 tained ; there were as many species as all our former dredgings com- 

 bined produced : — the depth was from fifteen to twenty fathoms, the bot- 

 tom soft and rather oozy. Among them was this new species. 



H. hirsnta, Flem. 



Strangford Lough, W. T. 



H. suberia, Mont. 



This species, as represented by Dr. Coldstream, has occurred to me in- 

 vesting univalve shells dredged in the Loughs of Strangford and Belfast. 

 In the former locality I, in 1835, obtained the Spongia ? suberia, which in 

 the Magazine of Natural History, vol. vii. p. 491, is described and figured 

 by Dr. Johnston, who considered it the " perfect state of the H. suberica." 



Sept. 21th, 1847. — Dredged from 20 fathoms, entrance Belfast Bay. 

 When recent, this species is often on the upper side {i. e. upper as to the 

 motions of the Pagurus inhabiting the Turritella terebra, on which the 

 sponge is based) bright orange, much paler on the under side, or that from 

 the light. The shell on which this sponge grows is almost invariably 

 tenanted by a Pagurus of some species : species various, AV. T. Carling- 

 ford, Mr. Hyndman. 



H. mammillaris, MiiU. 

 A specimen of this sponge, which I have not seen referred to as identi- 

 cal with any British species, was dredged in Strangford Lough, in 1835, 

 by Mr. Hyndman and myself. 



H. carnosa, Johnst. 

 The only locality for this species given in Dr. Johnston's work is 

 Roundstone Bay, Connemara. The author omitted noticing the species 

 as from Strangford Lough, where I dredged it in July, 1838, and sent it
