the lower surface of another. The smallest anthocyathus found free 
is represented in fig. 17. It has an obvious scar oF detachment. 
This species is easily disiinguishable from all other ones of 
this group by its extremely irregularly dentated and fenestrated 
septa. It has some resemblance with F. patelliformis. but its septa 
have a quite different form. Moreover in F. patelliformis the costae 
are visible from the periphery to the centre, whilst in F. laciniosa 
the central part of the costae is less distinet. From F. erosa Do- 
derlein F. laciniosa also differs by having mueh less prominent 
costae and especially by its peculiar thick, spongy septa. 
The smallest specimen is a short stalked anthoblast (fig. 23), 
the anthocyathus of which has a greater diameter of 6, a lesser 
diameter of 5,5 mm. The measurements of a number of larger 
specimens are given in mm in the table below:

The largest specimen in the collection has six complete cycles 
of septa and some members of the seventh cycle. 
One specimen has apparently regenerated from about one half 
of a broken corallum. The outeome is a nearly circular form with 
only few irregularities in the arrangement of the septa. Its lower 
surface presents only indistinet traces of the former incompleteness.

In the various stages of growth this species is always easily 
to be distinguished from the other ones of the patella-gvoup by
