All the above — except Plagiophthalmus oviformis, the Hemiaster 

 identified as hufo, and the Gyprina — occur in the corresponding 

 beds on the coast. The Holaster alius, Ag., is described in a 

 separate note (see p. 246). 



Some lumps containing remains of silicified sponges were sent to 

 Dr. G. J. Hiade, but they were not in such a state as to allow 

 even of generic identification.

The geotectonic position of the outlier has also some points of 

 interest. From the high ground near Honiton (Honiton Hill, etc.) 

 the general dip of the beds is easterly, till they are cut off by 

 a long and powerful fault which, near Hayne Farm, brings the red 

 Triassic marl up against the Cenomanian sand, and has here a throw 

 of at least 300 feet. Near Wilmington this fault branches into 

 two, and a long narrow strip of Greensand is wedged between the 

 Chalk on the west and the Red Marl on the east; this strip, 

 however, seems to thin out near Sutton Barton, for the well at that 

 place is 108 feet deep, and is said to have traversed some thickness 

 of chalk before reaching sand. 



The surface of the ground is very irregular, and the valley- 

 system has not been influenced in any way by the lines of faulting ;
