jecting. There is a broad low median tooth, tlie corners of which 

 are sometimes a Httle pointed. The well-developed oral arch, the 

 height of which is contained 10—12 times in that of the whole 

 zooecium, is more or less sharply divided into a larger median por- 

 tion, provided with a more or less convex margin, and two much 

 lower lateral portions. The small fragments described above have 

 no ooecia, but I have examined colonies from several other localities, 

 the ooecia of which are developed from kenozooecia. The punctures 

 in the margin of the ooecia of E. laqueata mentioned by Norman and 

 HiNCKS belong really to the surrounding kenozooecia. In the de- 

 scription of E. abijssicola they are not mentioned. 



Two small fragments of old injured colonies on a stone.

This species is subject to great variation, and colonies from 

 different localities show diversities in the form of the ooecia, the 

 median tooth and the vestibular arch.

A number of small colonies on stones and on algæ. The ro- 

 strum and an unpaired avicularum are rarely developed, and in 

 some of the colonies the zooecia are provided with two widely se- 

 paratçd oral spines.
