BEroRT — 1884. 



all that concerns us in the present Report — are placed after the numbers 

 14, 15, 16, and 20 in his cosmopolite list. It is useless to reproduce the 

 definitions of these genera as given by Goldfuss, for the very simple 

 reason that these names now used are much more restricted, and, com- 

 paratively speaking, have a different meaning. With regard to the use 

 of the generic name Ceriopora, I may say that authors differ in opinion 

 as to the necessity of its further retention. Generally speaking I agree 

 with those who desire the suppression of the word ; still, there are some 

 forms given by Hagenow, which will be referred to further on, that may 

 conveniently retain the name, but the genus Ceeiopoea, Goldfuss, embraces 

 many typical forms that have been handed over to at least five distinct 

 genera. The Cretaceous Retepora of Goldfuss, and also the Cellepora 

 and Eschaea, are also placed in hostile relationship, which will be more 

 apparent when I review the labours of Hagenow. I cannot attempt any 

 suggestive arrangement of Goldfuss's genera and species, because by so 

 doing I should anticipate work that will be done further on. I merely 

 take the lists given by him as found in the Maestricht beds, and the 

 Cretaceous rocks of Essen.
