 Hah. " A few fathoms beyond low water-mark," common on all our 

 coast. 



Polypidom attached by capillary roots, from 2 to 4 inches long, 

 very bushy, " in cupressi formam elongata," greyish-white, flaccid 

 even when dry ; the branches close, erect, dichotomous, filiform, con- 

 sisting of a series of paired cells divided by a simple joint. Cells 

 adnate, smooth, obliquely truncated, placed back to back, "• so that the 

 pair together resemble a coat of mail, or pair of stays ; and the en- 

 trances of the cells look like the places for the arms to come out at." 

 Ellis. The Polypes have 10 tentacula : they have no gizzard, but 

 in other respects the alimentary canal presents the usual details. 

 Farre. 



2. N. ? BURSARiA, cells compressed, keel-shajjed, " ivith a little 

 tube, sivelling at top like a tobacco-pipe, that appears to come out 

 of them:' Ellis.

 Hah. Parasitical on sea-weeds, very rare. " Mare anglicura, in 

 cujus fucis crescit parasitica," Pallas. 



" This most beautiful pearl-coloured Coralline adheres by small 

 tubes to fucus's, from whence it changes into flat cells; each single 

 cell like the bracket of a shelf, broad at top, and narrow at bottom ; 

 these are placed back to back in pairs, one above another, on an ex- 

 tremely slender tvdie, that seems to run through the middle of the 

 branches of the whole coralline. The cells are open at top. Some 

 of them have black spots in them : And from the top of many of 

 them, a figure seems to issue out like a short tobacco-pipe ; the small 

 end of which seems to be inserted in the tube that passes through the 

 middle of the whole. 



" The cells in pairs are thought by some to have the appearance 

 of the small pods of the Shepherd's Purse : By others, the shape of 

 the seed-vessels of the herb Veronica or Speedwell." Ellis.
