Mr. P. H. Gosse on some new British Sea- Anemones. 195 



Mouth large, protrusile : lip sharp : tliroat evertile, coarsely 

 furrowed. 



Colour. Column a rich orange^ or orange-scarlet, with the 

 warts either paler or darker than the ground-colour. Edge of 

 parapet cream-white, immediately below which the margin is 

 marked alternately with square patches of dark purplish choco- 

 late, and narrower spaces of whitish (twelve marks of each 

 colour in adults, six of each in young) ; these, from the fine 

 contrasts of colour, when the button is not quite closed, have 

 a very striking and characteristic effect, as if the animal were 

 surmounted by an elegant coronet. Hence I have selected the 

 nomen triviale. 



Disk red, varying from pellucid scarlet to a reddish chocolate ; 

 each radius bearing a longitudinal central streak of white, which 

 does not reach either tentacle or lip, and bounded by a very fine 

 white line on each side; thus is produced a pattern of fine 

 radiating lines of white on red. Sometimes the lines are irre- 

 gularly blotched and dilated, -with ragged edges. 



Tentacles pellucid, nearly colourless, crossed by three dim 

 subopake white bars, of which the middle one is most distinct ; 

 near the base are two chocolate bars, generally divided by a 

 central longitudinal line of pellucid white, giving the appearance 

 of four dark spots set in square. Sometimes one bar is nearly 

 or quite obliterated. 



Lip whitish. Throat rich orange- scarlet ; the furrows darker 

 than the ridges. 



Size. Diameter of column in button, one and a quarter inch ; 

 height two inches ; expanse of flower one inch. 



Locality. Off Berry Head, Devon ; in twenty fathoms. 

 Several specimens dredged, adhering to the shells of living 

 Turritella terebra. 



A very fine and showy species. 



Fam. IlyantMdse. 

 Genus Halcampa. 



Sp. 4. Halcampa microps (mihi). Tentacles papillary, without 

 markings. 



General Description. — Form. Column cylindrical ; 8-invected, 

 the tegumental insertions of the septa being the boundaries of 

 the swellings ; hinder extremity inflatable, protrusile, adhesive : 

 skin minutely granular, enveloped in a thin mucus which entan- 

 gles foreign matters ; ordinarily covered with minute, close-set, 

 transverse wrinkles. 



Disk the rounded anterior extremity of the column, around
