ANGUINARIA. 



attracted my attention, were not distinct polypidoms, but 

 little tubular pores, springing from a fistular fibre, which 

 ran in an irregular line along the frond, adhering closely to 

 it. This creeping fibre, at pretty regular intervals, spread 

 out into cells in the form of Hippothoa; and from the blunt 

 end of the enlargement the tubular spores arose, of the 

 same texture as the creeping fibre, and showing the reddish- 

 coloured remains of the polype that had inhabited them. 

 It was unlike anything I had seen before. In reading 

 Mr. Couch's description of his Hippothoa sica, I found 

 that he said, " the apertures are rather small, and as usually 

 seen are round, even, and unarmed; but, in recent and 

 living specimens, they are long and tubular, frequently as 

 long as the cell. In this state it may be taken for a species 

 of Tubulipora" This description in part suited my little 

 creeper, but it was deficient in the regular symmetry of 

 Hippothoa. Could it then be Anguinaria on a flat frond ? 

 The upright pores were not bent like A. spathulata, and 

 showed nothing of the serpent-like head. They were 

 Kke a small quill cut across, and then a longitudinal slice 

 cut off towards the top, as the first step in the process of 

 making the quill a writing-pen, so that it was open so far 

 like A. spathulata, but unbent ; and truncated instead of
