sidence is rarely met with in these islands. 2. In the Pelew Islands, as 
proved by Semper, all forms of reefs are met with, and at the same time 
strong evidences of recent upheavals. 3. In no geological formations are 
coral reefs met with of the thickness requisite for a belief in the subsi- 
dence theory ; and finally, the submerged mountains which the atolls, 
&c. , are supposed to crown, are not in all cases to be found.

In Sagartia and Anthea a tryptic enzyma was dissolved out of the 
mesenterial filaments by water ; in Cerianthus a peptic one. The anal 
pore, when present, does not serve for the purpose of the discharge of 
fa3cal matter, but for that of the generative products and the expulsion of 
water.

The form and structure of the two genera Cyclophyllum and Aulo- 
phyllum are so different from all other groups of corals, that the author 
considers it necessary to separate them under a new family, which he 
proposes to call Diplocyathophyllidce . The double cup and septal system 
around the inner margin of the inner cup suggest the probability that 
these septa are the expression of a double circlet of tentacles, and on the 
strength of this the author figures a restoration of the genus Cyclo- 
phyllum.
