(Plate lxxviii., tig. 12.) 



Zoaria erect, with zooecia on all sides. Zooecia flask-shaped, 

 surface minutely granular with a few small perforations. Thy- 

 rostome orbicular with a raised margin in which is sometimes a 

 minute pore, probably avicularian. On the front of some of the 

 zooecia there is a long spatulate avicularium. 



Obs. — This species differs from L. hystrix in that the necks of 

 the flask-shaped zooecia are shorter, the thyrostome has a raised 

 margin and in the presence of the long spatulate avicularia on 

 the front of the zooecia. A single specimen.
