440 J. F. Walker — Liassic Sections near Bridporf. 



From the lower part of the hard limestone : 



Rhynchonclla Bouchardi. I Ammonites [Hildoceras) hifrons. 



Waldheimia Lycetti \ Ammonites [Harpoceras) falciferum. 



And from the Upper part ^wmo?n7es (ITarpoceras) striatulum. Mr. II. 

 B. Woodward also records the occurrence of this Ammonite at 

 Allington. It will be observed that the thickness of the bed B, 

 including the marlstone, is only 1 foot 8 inches ; in the section on 

 the other side of the road it was 2 feet 4 inches, but the bed was 

 probably thicker in some parts of this field, as I was informed that 

 large quantities of stone were formerly obtained from it. The 

 ]\Iailstone fossils in this quarry were not found mixed with Upper 

 Lias species in the same blocks of stone. 



There is an indication of the presence of the Jurense zone in the 

 upper part of the stone band. 



Some peculiar forms of Brachiopoda occur in this quarry which 

 require careful study. 



III. — A deep cutting in Shoots Lane, Symondsbury, which was 

 overgrown with vegetation, appeared to show the following sections : 



ft. in. 



(1) Sandy clay, overgrown, about... ... ... ... 10 



(2) Dark ferruginous rock containing nodules and worn 



small specimens of Ammonites [Hildoceras) bifrons 5 



(3) Light coloured stone 1 2 



(4) Stone band (in three divisions) 1 6 



(5) Marlstone 2 11 



(6) Soft brown sandy stone 4 



(7) Clay , 6 



(8) Overgrown ... ... ... ... ... ... 3 4 



This section was again carefull}' measured by the Rev. J. L. 

 Templer and myself in 189L The chief peculiarities are — the 

 occurrences of a conglomerate bed above the junction bed containing 

 worn specimens of Ilildoceras hifrons. Mr. S. S. Buckman kindly 

 examined these specimens and agreed with my determination of 

 them ; this indicates that while this bed was being deposited in 

 this section, denudation of the bifrons zone was taking place else- 

 whei-e. The junction bed appears to be represented by the three 

 stone bands. 



The marlstone contains Rhynchoiiella serrata in its upper, and 

 JUnjnchonella tetrahedra in its lowest part. Shoukl this lane ever 

 have to be widened no doubt many fossils will be found. 



IV. — In the year 1887, the supply of stone from the Forest 

 Marble having fallen short, a hole was made on the roadside of 

 Shipton Long Lane, Bothenhampton, for road metal ; unfortunately 

 the police ordered this hole to be filled up before it had time to 

 weather. It was about 5^ yds. long, o yds. wide, and 65 ft. deep, 

 which is equal to between 30 and 40 cubic yards of solid stone. It was 

 all in one block and required 11 lbs. of gunpowder to blast it. From 

 information obtained from the workman, by measurement of the 

 blocks and many days' work at breaking them and carefully collect- 

 ing the fossils, the following appeared to have been the section : —
