 Exterior aspect: The pedal disc is wide. The body is, according to the state of contraction, 

 cylindrical, conical or flattened, in contracted specimens the height of the column is commonly shorter than 

 the diameter of the base. The column is furnished with lines of verrucae which appear more or less distinctly, 

 according to the state of contraction. In a part of the specimens I have not been able to verify with certainty 

 the presence of verrucae, it may be possible that such ones are sometimes lacking, which is very difficult 

 to determine in contracted and badly preserved material, above all as the verrucae are rather small. I have, 

 however, obser\-ed that the verrucae become inconspicuous by a strong contraction of the column. As an 

 instance I can adduce that a specimen with very distinct, though small verrucae on a great part of its circum- 

 ference shows no trace of verrucae in the remaining, strongly contracted part. If the specimen had been strong- 

 ly contracted in all places, it would have been considered to be devoid of verrucae. On most specimens there 

 were however distinct verrucae. How far they expand on the column I cannot with certainty decide. On some 

 specimens I have observed them only in the distal part, on others the distribution of them was considerably 

 more extensive, the most proximal part is, however, probably always devoid of such. There is a well marked 

 fossa. Acrorhagi and pseudo-acrorhagi are wanting. The tentacles variate a little in number in the examined 

 specimens. Excepting a small, not adult specimen with only 45 tentacles, the others had from 64 to 90 tentacles
