Plate XX. Fig. 2, 3. 



Grantia lacunosa, Bean MSS. 



Hah. On rocks at low-water near Scarborough, very rare, 

 Mr Bean. 



Sponge half an inch in height, flabellate, pedicled, entire or 

 undivided, white, greatly compressed, the sides perforated with 

 numerous irregularly elliptical holes or vents, so as to give a 

 lacunose appearance to the dried specimen : structure compact, 

 friable when dry ; spicula all triradiate. The remarkable cha- 

 racter afforded by the numerous large holes in the sides, so un- 

 like the fecal orifices of the other species, distinguishes this at 

 once, and removes the suspicion of its being a variety of any 

 other. 



3. G. CI LI ATA, sponge elliptical or tid)idar, rough and 

 villous, the vent terminal and surrounded with a fringe of 

 erect asbestine spicula.
