stereoplasm, and that the septa are strongly dentated. The typo 

 form is from Eocene strata at Parnes and Grignon, France.

This species has never been figured. The Astrea ramosa, 

 Defrance *, on which it is based by Edwards and Haime, is a very 

 doubtful form, of uncertain origin, and it is not definitely known 

 whether it is fossil or recent. The description given of the species 

 by Edwards and Haime is equally vague, and there is no appreciable 

 difi'erence between it and that of 8. Forbesi. These authors claim 

 that the A. ramosa, Defrance, is synonymous with Septastrcea suh- 

 ramosa, d'Orbigny, but there is not sufficient evidence to support this 

 view. D'Orbigny, on the other hand, whilst holding that the S. 

 ramosa, E. & H., may be included in Septastrcea, denies that it is 

 synonymous with his S. subramosa, which he asserts is the same 

 as S. Forbesi, E. & H. At present it is impossible to determine, in 

 the absence of figures, whether A. ramosa properly belongs to Sep- 

 tastrcea, or if it does, whether it can be separated from S. Forbesi.

Accepting as correct Prof. Duncan's reference to and figures of 

 this species, it is very evident that it does not belong to Septastrcea ; 

 for there is no infilling of stereoplasm, the calicos are deep, and the 

 increase is by fissiparity. The species is from the Lias of Brocastle, 

 S. Wales, and Pont d'Aisy, Cote-d'Or, Erance.

The characters assigned to this form are entirely insufficient to 

 determine the genus to which it belongs. It does not seem to have 

 been figured. It is stated to have been derived from Portland 

 strata at Marcey-sur-Saone, Erance. 



Septastr^a explanata, de Eromentel.

 As in the preceding case, the scant description without a figure is 



altogether valueless to establish either the species or the genus to 



which the form belongs. It is said to come from Bajocian strata at 



Mantz and Voucourt (Haute Marne), Erance.
