Remarks. This species was established by Morton upon three 

 fragments, one of which gives the characters of one lobe of the 

 septa with small portions of others. In regard to the species 

 Hyatt says, "After examining the fragments of this species in 

 the collection of the Academy of Sciences, Philadelphia, I am 

 unable to determine with certainty whether this is a species of 

 this genus or not, and the details of the sutures, so far as my 

 hasty examination went, were too imperfect to enable me to 

 make a reasonable guess with regard to their affinities." 



Formation and locality. Cretaceous, New Jersey (Morton). 



Geographic distribution. New Jersey.
