more closely with that of Duchassaing and Michelotti. How- 

 ever the earlier descriptions are all too indefinite to make the 

 identification certain and it will perhaps lessen the chances of 

 confusion in the future to accept Mr. Duerden's separation of 

 the present species under the specific name he has chosen.

The base was evidently adherent, but though its ectoderm 

 was preserved no signs of a horny secretion were present. The 

 column was practically cylindrical, tapering slightly above and 

 measured 2.7 cm. in height, the diameter near the base being 

 about 2 cm., or rather since the column was flattened slightly 

 the diameter in one direction was 2.5 cm. and in the other 1.5 

 cm.; near the margin it was 1.6 cm. and 0.9 cm. 



The column wall was of a firm coriaceous texture and was 

 marked by fine longitudinal and transverse lines probably due 

 to contraction. The ectoderm was almost completely mace- 

 rated away, the few fragments of it which persisted being of 

 a dirty cream white color. A short distance above the base 

 there were a number of purple brown spots or tubercles ar- 

 ranged in two horizontal rows; both rows were somewhat 

 incomplete, some of the tubercles probably not being evident 

 on account of the loss of the ectoderm. In the upper row I 

 counted only four tubercles and in the lower only 6 (7?), the 

 lower tubercles being considerably smaller than the upper ones. 



The tentacles were marginal and were small and numerous, 

 being too crowded to count accurately. Those of the inner-
