Genus VERTICILLITES, Defrance, 1829. 



From the descriptions and figures of the type of this genus, Verticillites cretaceus, 

 Def., given by the author *, and more recently by Steinmann f , it would appear that 

 its minute structure is quite unknown ; and the peculiar circumstance of its occur- 

 rence as merely empty moulds, leads me greatly to doubt whether it really is a 

 Calcareous sponge. Steinmann places it with the Pharetrones solely on account of 

 its outer form. Unfortunately the Museum does not possess an example of the type 

 species, so that I have not had an opportunity of seeing it ; but until its minute 

 structure is known, it will be necessary to exclude from the genus other species with 

 a definite spicular structure hitherto placed under it by different authors. The genus 

 Verticillites, and its synonym Verticillojwra applied by BlainvilleJ to the same 

 sponge, will therefore be restricted to its type species V. cretaceus.
