EeTEPOEA SPATULIFEEA, Sp. DOV. (PL 29. figs. 4, 5.) 



The specimen from Station No. 4 has narrow strap-shaped 

 branches, which anastomose irregularly ; but other specimens, 

 with very similar zocecia, have the zoarium regularl}^ reticulate. 

 On the anterior surface, below the aperture, there is a round 

 avicularium close to the oral slit, also there are round avicularia 

 on the front of the zooecium, usually one or two to each zooecium. 

 The pair of oral spines are articulated, and usually, in the 

 specimen from Station 4, become very wide towards the end, 

 having the same shape as the club-shaped spines of Microporella 

 spatulifera, Smitt, as figured in my paper* on "Bryozoa from 

 Franz-Josef Land," and the specific name is chosen on account 

 of this similarity. 



The ovicell, which is but slightly raised, has a fissure down the 

 middle. I am not aware that the ovicell of typical H. magellensis, 

 Busk, has been described; but it occurs with a fissure in speci- 

 mens from the Straits of Magellan shortly to be described by 

 Calvetf. In JR. spatulifera the dorsal surface is divided by 

 vibices, has numerous small openings and round avicularia. 

 There are 13-14 tentacles. 



This is very similar to R. magellensis, Busk, in most particulars, 

 but in the specimen from Station 4 differs in the shape of the 

 branches and in their irregularly anastomosing ; though in the 

 specimen from Station 167 the zoarium is reticulate, as in 

 B. magellensis, and the articulate spine is more delicate, being 

 seldom club-shaped.
