arrondie, polypierites unis par leurs murailles ; planchers infundibuli- 

 fornies." In the description of the only species of the genus the 

 authors further add, " Nous ne savons pas, s'il existe reellement des 

 trous aux murailles." The above generic description is of so wide 

 and general a character that it would certainly include rny new 

 form, and at first disposed me to refer it to Bcemeria ; but having had 

 the opportunity (for which I am indebted to the obliging courtesy 

 of Professor Andrea, of Bonn) of making a close examination of the 

 original specimens, upon which Goldfuss and Edwards & Haime 

 based their descriptions, I find that the differences are too great to allow 

 the forms in question to be placed in the same genus. Thus in Bcemeria 

 [Calamopora) infundibulifera, the corallites have unusually thick 

 walls, and are not in contact at their summits, which are circular. 

 There is, further, the very important fact, that no mural pores can be 

 distinguished in the specimens, notwithstanding the statement of 

 Goldfuss that such existed ; and the character of the corallite walls, 

 and their separation from each other at the surface of the 

 corallum, tends to negative the probability of their presence. Again, 

 there is no appearance in the type specimens of the open central 

 tube as shown in Goldfuss' figure (plate xxxii. fig. 1 b), but there are, 

 instead, funnel-shaped tabulas resembling those present in the genus 

 Syringopora, consisting of a series of elongated closed cones closely 

 fitting into each other. The specimens of B. infundibulifera may, 

 indeed, be compared to a Syringopora, in which the connecting pro- 

 cesses are absent, and the corallites are in contact with each other. 

 There are, besides, no indications in Bcemeria of septal spines. It is 

 thus apparent that there is sufficient divergence in the characters of 

 Bcemeria, as shown in the only known examples of the genus, and 

 Syringolites, to justify the separation of these forms into distinct 

 genera. 



Syringolites Huronensis, Hinde. 

 A. Fragment of a colony of the natural size. B. A single calice of the same, 

 enlarged eight times, showing the central tuhe and radiating lines of septal tubercles. 

 C. Part of a corallite of the same, split open and enlarged six times, showing the 

 composition of the central tube out of invaginated tabula?. D. Part of a corallite of 

 the same viewed from the exterior, and enlarged six times, showing the mural pores. 



The only difference between Syringolites and Favosites (Lamarck) 

 (= Calamopora, Goldfuss) consists in the central tube and the rows 

 of septal spines on the tabular surfaces and in the tube of the coral-
