352 APPENDIX. 



a ring a little deeper than the general hue ; the region below the warts 

 studded with much more minute aud more crowded whitish specks. 



Disk. Pale buff or drab, unspotted ; pellucid. 



Tentacles. Pellucid white ; a broad scarlet ring, bounded below by a 

 narrower one of opaque white, surrounds the middle of each tentacle. 



Mouth. Lip as the disk. Gonidial tubercles white. Stomach-wall 

 marked with alternate lines of pellucid and opaque white. 



Size. 



Height of column, when distended, four inches, diameter nearly the 

 same ; expanse of flower about seven inches. 



Locality. 

 North Sea : deep water. 



The acquisition of the magnificent animal above de- 

 scribed, for which I am indebted to the kindness of Mr. 

 D. Ferguson, of Coutham, not only enables me to augment 

 the genus Bolocera, and at the same time the British Fauna, 

 with another species, but also makes me better satisfied 

 with the establishment of such a genus. Equal in dimen- 

 sions to B. Tucdicc, and presenting much in common with 

 that species, there are peculiarities in this specimen which 

 compel me to consider it specifically distinct. These are 

 the brilliant hue of the column, its striate surface, the 

 thinness of the integuments, the much feebler sulcation 

 and constriction of the tentacles, and the rings of positive 

 colour which adorn them, together with their power of 

 complete retractation. All these characters make the pre- 

 sent species a decidedly nearer approximation to Tealia. 

 Indeed, when fully expanded, so remarkable is the resem- 

 blance in form, size, and colour, to a fine T. crassicornis, that 

 I have little doubt the reason of its having been hitherto 

 overlooked, is that it has been passed over as that familiar 

 species. Yet the minute warts, the (really though slightly) 

 constricted and furrowed tentacles, and the non-retractility 

 of the margin, determine its place in this genus. 



The nobleness of its tout ensemble, and especially the
