 pp. 460—463, pis. lxx, figs. 13—15 ; lxxii, fig. 11 ; lxxiv, fig. 11. Fig- 

 ures 13 and 15 of plate lxx are of macerated specimens somewhat 

 restored in drawing. Abrasion has modified the form of the sutures. 

 Those shown in the specimen represented in fig. 14 are immature 

 septa of (ton. Pattersorvi.

(G. sinuosus Clarke, p. 94 : "Specimens of Gon. intumescens which 

 have been exposed to weathering since fossilization or maceration 

 before it, often exhibit peculiar modifications of the septa. The 

 specimens found in the thin sandy layers or flags are usually thus 

 modified and in some of their conditions are similar both in exterior 

 and septum to those which have been described as G. sinuosus and 

 G. nundaius. I am at present inclined to believe that G. sinuosus 

 is only a condition of G. intumescens resulting from modification by 

 mechanical and post-vital influences.")
