Figure 1. A large fragment representing the upper part of a frond of great 

 size. Fragments of this character abound at the locality from which 

 this was obtained, but so large and fragile was the sponge that no 

 entire individual has been obtained and but very few specimens 

 which aiford a clew to the original form of the species. Elsewhere 

 is given a drawing of the apical portion of one of these sponges 

 ^vhich shows that it was doubtless a Dictyospongia. 

 Chemung group. In a bed of grey mndsbone, at Almond, New York.
