Exterior aspect. The column is strongly elongated, in the 
undermost part with 16 distinet longitudinal furrows probably cor- 
responding to the insertions of the mesenteries. Above this region 
an area with very small papillae only perspieuous with a strong 
magnifying glass. The cylindrical tentacles are certainly not more 
than 10. The actinopharynx is evaginated owing to a strong con- 
traction of the distal part of the body and provided with numerous 
longitudinal folds. The siphonoglyphe is broad and furnished with 
a small tentacle-like conchula (textfig. 6). 
Anatomical description. For the anatomical examination 
I have sectioned a piece transversally rather below the actino¬ 
pharynx and a piece of the evaginated actinopharynx region and 
made maceration preparations of the ectoderrn in the column, ten¬ 
tacles and actinopharynx. The maceration preparations of the column 
are taken from its undermost part as the ectoderrn was lost in the 
other regions. Concerning the size of the nematocysts and spiro- 
cysts I refer to the diagnosis. The smaller nematocysts of the 
actinopharynx were rib-like, the larger broader at the basal end 
which is sometimes square, the basal part of the spiral thread and 
the thread itself perspieuous. The actinopharynx as also the siphono¬ 
glyphe agree in structure with other Peachia species. Not having 
sectioned the upper part of the actinopharynx I cannot, however, 
decide if a strongly ciliated boundary zone is present between the 
actinopharynx and the siphonoglyphe (compare Carlgren 1921, 
p. 102). 
The mesenteries were only 16. Of the 6 pairs of the first order 
only the 5 first couples were perfeet and provided with pennons, the 
sixth couple (the ventral mesenteries of the ventrolateral pairs) is 
imperfeet and devoid of pennons but furnished with filaments as
