the two following species being Dublin Bay, I shall here copy some 

 notes upon them ; — their forms have been known to me since 1835, 



Halichondria incrustans, Espcr. (sp.), Johnst. B. S. p. 122. pi. 12. 



fig. 3. and pi. 13. fig. 5. 



Abundant, adherent to rocks between tide-marks on the Down 

 coast. Dr. Johnston calls it an " unattractive species," in which — 

 but it is a matter of mere taste — I cannot agree. Its reddish orange 

 colour on the dark rocks is to my eye most lively and pleasing, and 

 more particularly so, when other sponges are in its immediate prox- 

 imity. At Ballyholme, Belfast Bay, within the space of a very few 

 square feet, this species may be seen in small orange patches on the 

 rock ; Hal. panicea in green masses, and by throwing aside the hang- 

 ing fronds of Fucus nodosus (covered by their parasite Polysiphonia 

 fastigiata), Ptilota plumosa densely clothing the shaded rock is ex- 

 posed to view, and on it the Grantia botryoides and G. foliacea grow 

 plentifully, and the G. ciliata is sparingly seen. 



Although H. incrustans inclines generally to look directly down 

 upon the water, or to grow on the under surface of rocks (see Grant, 

 quoted in Johnst. B. S. p. 124), I find it also attached to their per- 

 pendicular sides, and when so, the " fecal orifices " are elevated, but 

 not very much, above the surface. 



Grantia coriacea, Mont, (sp.), Johnst. Brit. Sponges, p. 183.
