Genus Heteropora. p. 539. 



A species of this genus from the Tertiary of Petersburg, N. C., is described by Lons- 

 dale, as having no transverse septa in the cells within the coral lum, which character would 

 remove the group from the neighbourhood of the Helioporas.

Poriles : Appendix. p. 568. 



Poriles cervina. (Lamarck.) " P. pumila, gracilis, dichotomo-ramulosa ; stellis dis- 

 tinctis ; margine prominulo, ciliato." This species is referred to the genus Seriatopora, 

 by Blainville. (Lamk., ii. 438, No. 11 ; Deslongch., Encyc., 653. Seriatopora cervina, 

 Blainv., Man., 397.) 



Forties angulata. (Lamarck.) " P. ramis contortis, lobatis, compressis, angulatis ; 

 stellis in fbssulis immersis ; margine denticulis scabro." (Lamk., ii. 438, No. 9 ; Des-

GLOSSAKY. 



It has been found necessary to apply more definite significations to some terms than 

 they have hitherto received in this department of zoological science, or to use them in a 

 modified sense; and a short glossary is here added for the convenience of reference. 



1. General Terms. 



Zoophyte. An individual in this order of animals, whether a solitary polyp, or a com- 

 pound group. 



Segregate. The polyps of a group, disunited except at base. 



Aggregate. The polyps united throughout laterally, as well as at base.
