302 BIOLOGICAL SURVEY OF 



reaches the upper part of the stem, it widens rapidly and 

 irregularly between the other tubules. Its exposed portion 

 is distinctly swollen or obese in appearance. The ooeciopore 

 is terminal or nearly so, closely associated with and partly 

 surrounding the base of one of the projecting tubules. It usu- 

 ally appears as a lunate opening at the same level with the 

 ooecial wall, or somewhat indented into the wall of the related 

 zooecial tubule. In only one case of the many examined w^as 

 the ooeciopore separated from a tubule, and in this case the 

 ooeciopore was rounded. The other characters were so simi- 

 lar that I call attention to it for the present merely as a 

 variant form. 



I also have specimens from Georges Bank and from off 

 Cape Sable. The species which Cornish listed as Entalophora 

 ciavata Busk is probably this form. Miss Hastings writes: 

 "I cannot find any specimen of Entalophora agreeing with 

 yours in our collection." There have been many species de- 

 scribed in Entalophora which are unidentifiable, as they were 

 based on zoarial characters. The present species may be one 

 of these, but as it is impossible to know with certainty, it is 

 described and named as new, and may be known from the 

 ooecial characters, upon which w^e must depend for definite 

 identification. 



I take great pleasure in naming this species in honor of 

 Sir Sidney F. Harmer, former Director of the Natural His- 

 tory Departments of the British Museum, who has contributed 

 so greatly to our knowledge of the Bryozoa, and especially to 

 our understanding of the nature of reproduction and the 

 ovicell in the Cyclostomata.
