The other stem mea- sures about cm in length and bears full-grown zooids. The interval between the base and the lowermost full-grown zooid is 30 mm, and the intervals between the zooids varv from .ibout 5 to 9 mm. The stem in the lower i>art a diameter of about mm, having about 25 mm above the base two small zooi(b buds, less than mm high, ]ilaced 2 mm a]xirt. The verrucae measure about 3x1 mm. The colonies from the ''Ingolf" St. tu are of much varving size, the smallest measures about cm and the largest mav, when alive, have measured niori' than 50 cm in length. The interval between the and the lowermost zooid is about (10 mm in a 45 cm high colony, in a 3!t cm high colonv abont MO mm, in a 25 cm high cohniy about 75 mm, and in a lOcni high colony about 45 mm. The largest interval between the base and the lowermost zooid is found in the colonv 31 em high, from ""Ingolf" St. 68, and measures aliout '.15 mm. Tliicula- tion of the stem, as will be mentioneil below, differs somewhat from the typical. The colonies are erect, slightlv sjiuallv turned, and the larger s])ecimens are rigid, only towards rhe tip somewhat flexil)le. The axis is roundish, having the .surface ])rovided with short longi- tudinal .scratidies. In the smaller colonies the colour of a.\is is whitish and light-blue irridescent, in the lower ]iart of the medium- sized colonies more yellow anil in the larger colonies slightly light-brown.
