Judging from his description and figure the Lobopsammia robusta of Bourne is synonymous 

 with this species. Thai fissiparity does not occur is very apparent; Bourne thought it did.

1 am not quite sure about the identity of this specimen; it differs from the typical /> 



willeyi by the by far lar^er calicles; the biggest calicle in my specimen has a diameter of 



14 mm.. The ribs of my specimen are covered with one row of spines on the edge; these 



spines are clearly visible with the naked eye, there are about 25 in 1 cm.. 



In the typical specimen that prof. Gardiner kindly sent me there are no 



spines on the ribs. 



The arrangement of the septa deviates markedly from the common type 



as is shown in the accompanying diagram (fig. 8). This is the case in my specimen 



a-> well as in the typical one. The septa <>t the higher cycles are sometimes 



interrupted. 1 In different cycles are not always recognizable. but the formation of new septa

I li in this species are much shorter than in the preceding two species; the 



est one in my specimen is only 12 mm. high.
