 Forh. 1867, Bihang, 29 and 179. 



Zoarium yellowish white, shining, dichotomously branched ; 

 branches slender, compressed, of nearly equal width 

 throughout, blunt and generally bifid at the extre- 

 mities, disposed nearly in the same plane, occasionally 

 anastomosing, given off from a slender compressed 

 stem. Zooecia prominent, distinct, ovate-elongate, 

 finely granulated, quincuncially arranged ; orifice arched 

 above, slightly curved inwards below ; wall of the cell 

 raised and thickened round it; a circular avicularium 

 within the lower lip, and immediately below it a short, 

 blunt rostrum ; small circular avicularia scattered 

 irregularly over the cells. Ocecia small, globose, 

 closely united to the cell above, and inconspicuous, 

 slightly granulated; surface entire. 



Height 1 inch to 1^ inch. 



HABITAT. In deep water. 



LOCALITIES. Shetland (Barlee) : 20-25 miles north of
