M. py7^amidcdis in its shorter hydroecium, and from liis other 

 species in the toothing. 



In addition to the foregoing there are a number of specimens, 

 not in a condition for definite identification or description. So 

 far as can be determined they seem to belong to the following 

 species: — 



Sarsia eximia. Two specimens 



Sarsia 7^osario. One specimen. 



Atollia hairclii. One specimen. 



Ohelia polystyla. One poorly preserved specimen. 



Vanhoeffen (33) gives a good figure of Atollia bairdii, with 

 which our specimen seems to closely correspond.
