Moseley makes some remarks about this unpublished species of Brüggemann, comparing 

 it with B. cornu and B. socialis. I am quite sure that 1 have before me representatives of the 

 same specii 



The following is a description of nn specimens: 



The conical corallum is very slender near the attached base, increasing in diameter 

 rapidly topwards. I h< ■ figured specimen has a diameter near the base of 9 mm., whereas the 

 elliptical calicular opening measures v> 24 mm.. The other specimens are even more slender. 

 The corallum is bent in some direction, it may be parallel to the long axis or parallel to 

 the short axis <>t the calicle. or intermediate between them. The wal! is covered by a dense 

 epithi from the base to about 1 cm. from the margin; sometimes the ribs are 



wholly concealed by this epitheca, though they are lor the must part still visible. 



In the upper part the ribs are apparent; they are broader or narrower independently 

 of the arrangement of the corresponding septa. The ribs are flat, roughly granulated, perforate 

 or not, separated Ia narrow, much perforated furrows. 



The septa are typically arranged in five cycles. The septa of the first and second cycle
