THE OKNATE ANEMONE. 



Sagartia ornata. 



Plate II. Figs. 9, 10. 



Specific Character. Basal region of the tentacles, and the outer region of 

 the radii blackish : a white bar across the former, and a white cordate spot 

 on the latter.

GENERAL DESCRIPTION. 



Form, 



.Base. Adherent to the roots of Laminaria : slightly exceeding the 

 column. 



Column. Minutely corrugated ; studded on the upper half with suckers, 

 more numerous as they approach the summit. Form in expansion elon- 

 gate, cylindrical. 



Tentacles. Moderately numerous, in five rows ; those of the first row 

 rather stoutly conical, comparatively short ; the rest diminishing rapidly 

 as they approach the margin. 



Mouth. Not raised on an obvious cone. Lip tumid. 



Aconlia. Emitted freely. 



Colour. 



Column. Dark orange-brown, paler at the base. Suckers pale. 



Dish. Central moiety pale orange, changing to a rich purplish brown on 

 the outer moiety. The radii of the first and second rows of tentacles 

 separated by narrow yellow bands slightly diverging " as they proceed 

 outwards, and at their extremities partially surrounding the bases of the 

 tentacles, accoz'ding to the following arrangement. The first tentacle may 

 be said to arise from the space between two pairs of bands, tbe second being 

 situated within the pair ;* the band bifurcates near its extremity, and 

 incloses the third tentacle : these branches again divide and form a similar 

 inclosure for the tentacles of the fourth row :+ beyond these is a set of 



* The apparent distribution of the bands in pairs is merely a necessary 

 result of the fact that the secondary radii are narrower than the primaiy. 



t Hence the yellow bands are doubtless the united radii of the tertian 

 and quartan series.
