slit-like mouth are folded. The sagittal tentacles are inserted at a greater distance from the 
oral cone than the lateral ones. Some parts of the polyps are rather transparent; the tentacles 
are transversally striped or wrinkled, perhaps caused by muscular contraction (?) since this species 
has rather well developed muscles, also in the tentacles. The polyps are separated by broad 
cross-grooves in the coenenchyma, but next to these there are also numerous finer grooves, 
much narrower, which diverge and converge alternately as in Eucirripathes angtdna (Dana), 
around the base of the polyps. Only a few spines can be seen through the coenenchyma. 
Diagnosis : 
Colony: irregularly curved and twisted into a loose ball, at first regularly 
increasing and alter wards diminishing diameter; unbranched; top slender 
without increase of diameter. 
Spines: triangular, blunt or acute, both sides concave (the short spines) 
or only the distal side (the long spines); no p. and 155/2. on opposite sides of
