ASTRJiACEA. SAGABTIAD^. 



THE EYELET. 



Gregoria fenestrata. 



(Sp. nov.) 



Plate VII. fig. 3 ; XII. fig. 7 (magn.). 



Specific Character. Column green, with purple lines ; tentacles red. 



GENERAL DESCRIPTION. 

 Form. 



In addition to the characters giTen on the preceding page, I may add, 

 that in my specimen, (which may be immature,) the perforations are very 

 visible, with a lens : there are about six in an mtersept, of which five 

 are placed in quick succession near the summit, and one remote near 

 the base : they are not found in all the intercepts, from two to four im- 

 perforate ones intervening between those which are pierced. Under mag- 

 nification the perforations are rounder, and less eyelid-shaped than in the 

 Sagartia; they have a distinct granular layer exterior to them, though 

 their outline is in some cases very clearly defined, and even thickened. 



The tentacles are about forty-eight, arranged in three rows; all sub- 

 marginal : their form is nearly cylindrical, with very obtuse tips. 



Colour. 



Column. Translucent glaucous green, very pale; each longitudinal 

 furrow marked by a line of deep reddish-purple, decided but not well- 

 defined ; the loop-holes are each surrounded by a ring of the same colour. 



Dish and tentacles. Dull red, pellucid; exactly as in the common 

 varieties of A. mesemoryanihemum. 



Mouth. More decidedly lake-red. Throat glaucous. 



Size. 



Column about one-sixth of an inch in height, and one-fifth in diameter : 

 expanse of tentacles one-third. 



Locality. 

 The Scottish coast near Banff; half-tide level. 



Mr. Walter Gregor, of Banff, (after whom I have named 

 the genus,) has just favoured me with this little Anemone,
