Hymeraphia verticillata Bk. 



Laothoe verticillata (Gray). Proc. Zool. Soc Lond. 1867, p. 543. 



''This species was brought up from a depth of 100 fathoms by the 

 sounding line, by the officers of H. M. S. Porcupine" (Prof. "W. 

 King). Prof. 0. Schmidt observes that Dr. Bowerbank's genus Hy- 

 meraphia is without doubt closely connected to Microciona. Per- 

 haps this is less true of the present than of any of the other species 

 of the genus — the presence of verticellately spined spicula, and the 

 primary skeleton spicula being surrounded by a fasciculus of second- 

 ary skeleton spicula, are characters, with others, that forbid this 

 species to be placed in Schmidt's genus Scopalina. 



Hymeniacidon caruncula Bk. 

 Bantry Bay. Rev. A. M. Norman. Schmidt (I. c, p. 19) states this to 

 be a Reniera (Nardo). 



H. sanguinea (Grant). 



Dublin Bay ; Lambay Island (W. T.) ; Bertraghboy Bay and Arran (Dr. 

 Bowerbank and self) ; Connemara and Clew Bay (W. T.) Indeed it 

 is to be met with all round the coast. 



H. viridans Bk. 

 Glengariff (Rev. A. Merle Norman) ; Berehaven. 



H. aurea (Montagu). 

 Bantry Bay (Rev. A. Merle Norman). 



H. armatura Bk. 

 Strangford Lough (Prof. Dickie). 



H. floreum Bk. 



Carmia florea (Gray). Proc. Zool. Soc. Lond. 1867, p. 537. 

 Strangford Lough (Prof. Dickie). 



H. suberea (Mont.) 

 Suberites suberea, Nardo. fide Gray. Proc. Zool. Soc. Lond. 1867, p. 523. 



H. carnosa (Johnst.) 



Tethya carnosa Scouler. Ann. & Mag. Nat. Hist. 1846, xvii., p. 176. 



Suberites carnosa Gray. Proc. Zool. Soc. Lond. 1867, p. 523. 



These two latter species are common everywhere in suitable locali- 

 ties around our coast. It is often very difficult to distinguish between 

 them. 



Cliona celata Grant. 



I here record only one species of this genus, though I doubt not but 

 that I have specimens belonging to several others, which I reserve for 

 future study. The genus Cliona (Grant) should give place to Vioa
