392 'fames on Monticulipora. 
Alontlculipora^ "since if it were a character of real importance, 
such as the 'septa' of Ccelenterata it would be developed in all 
the species, which our present knowledge of these forms justi- 
fies us in saying, is not the case." (Jour. C. S, N. H. v, p. 147.) 
But the septa are not developed in all forms of Ccelenterata {^e.g. 
J^avositidce) and there are certain ?,-pecie%oi Monticuliporidcein 
which there are found projections from the wall of the cell into 
the cavity, {^ortoni and septosa for example,) which may or may 
not have been in the nature of septa. And further it should be 
remembered that in Heliopora^ certainly a true coral, the septa 
are but poorly developed, these being produced merely by the 
foldings of the walls of the corallites as may well have been the 
case with J\I. ortofii and others. 
Fifth; spiniform tubuli are stated to be developed in the 
majority of Mont iculipor idee as they are also in Heteropora. 
But these are 7wt found in briarea^ septosa and possibly others, 
for in the descriptions of many species no mention is made of 
them, and they are few to numerous in many species. 
Sixth, and lastly, in weighing the points of resemblance he.- 
Xv^^QwHeteropora -AwiS. Alojiticulipora^ Mr. Ulrich says, (Ibid, 
p. 146): (i) The colony is composed of two sets of tubes: 
(so also is the corallum of HelioUtes and other undoubted 
polyps); (2) both have their tubes crossed by diaphragms; (it 
is so also in Hcliolifes, Favosites^ etc.); (3) in certain types of 
Alonticulipora the interstitial tubes are in no way structurally 
different from the proper ones: (but so is it also in Ueliolites') ; 
while (4) in relation to the mural pores these are present or 
absent in the Aporosa (corals), and so can scarcely be considered 
as a sufficient character to depend upon. 
From all these things we fail to see why it would not be just 
as wise a course, if indeed not a wiser one, to place the Alonti- 
cuUporida: close to the Hcl/'oporidcv, as to remoAe them to the 
Polyzoa. Individually, and we are not alone in the belief, we 
believe that the Aloiificuliporida: constitute a family closely al- 
lied to the Hclloporidie^ and that they belong to the order Al- 
cyonaria of the class Anthozoa of the Coelenterata.

Britaniiica, written by Dr. H. A. Nicholson, and to that of Polyzoa, by 
Prof. Lankester, in the same work, for much of the information relating 
to the features of these two groups embodied in the above article. — ]. F.J.
