in the venation on the penultimate layer of Millepora alci- 
corns. 
But these views are opposed to those of Drs. Nicholson and 
Murie, in the report of whose paper on the minute “ structure 
of Stromatopora,” read before the Linnean Society on the 
20th Dec. last, we read that the authors “discard the notion 
of its alliance [that of Stromatopora] with the Nullipores, or 
belonging to the corals, Hydrozoa, or Foraminifera ;” while, 
“under negative evidence,” they would constitute for the 
Stromatoporids ‘a new order of calcareous sponges—NStro- 
matoporidea.” Herein, I need hardly state, it is impossible 
for me to acquiesce.

Lastly I must advert to the fossil from the ‘ Lower Chalk” 
of Dover, kindly sent to me by Mr. Woodward of the British 
Museum, last year, and described in the ‘ Annals’ (vol. xix. 
. 64) under the provisional name of “ Bradya tergestina,” 
Stache, MS.”—chiefly for the purpose of giving a figure of 
it, which I then had not the opportunity of doing, as my plate 
of illustrations had been filled up previous to its arrival. 
Having in my private journal, however, accurately sketched 
the upper portion of it, together with the section, of the natu- 
ral size, it is herewith reproduced (figs. 6, 7), as well as a 
magnified view of the fragments of the “ creeping, branched, 
tortuous, dendriform fibre in prominent relief,” mentioned at 
p- 65 (é.c.), that remains on its surface (fig. 8, a), and a 
diagram, to scale, of one of the tubular spaces (fig. 9, a), now 
observed to be septate like that of Millepora alcicornis. To 
the great resemblance of the stelliform systems of venation 
(fig. 6,aa) to, if not identity with, those of Stromatopora I have 
already alluded; I have also likened them to the “creeping, 
branched, tortuous, dendriform fibre in relief ”’ on the surface of 
the chitinous one, Hydractinia echinata ; and now they may be 
identified with the calcareous one on the surface of Mdillepora 
alcicornis. I have also since seen the base of this fossil, which 
presents no stelliform venation, but an irregular surface indi- 
cative of that of attachment, while the upper or sectionized 
polished part shows that the tubes had septa (tabule) like 
those of Stromatopora and Millepora alcicornis ; lastly, I ob- 
serve towards the periphery a great number of minute spheri- 
cal bodies of different sizes below the 3-1800ths inch in 
diameter, which appear to have been ova.
