186 REPORTS ON THE STATE OF SCIENCE. 
H.S.E. End of Section. 
From a measurement given me by Professor Lapworth, it appears that his 
specimens of Orthis Christianie, Kjerulf (?), were found at about 310 feet 
on the above section. 
Excavation No. 22.—50 yards North-West of the Comley Quarry. 
There is a prominent boss in the field lying north-west of the quarry, 
which proved on excavation to contain a quartzite agreeing very closely 
with beds b, and b. of Excavation No. 4, 1907, in the northern spur of 
Little Caradoc (see previous report). The rock is much fractured, but 
exhibits a north-easterly dip of 60° to 70°. 
Further trials were made in the field between this excavation and the 
quarry, but failed to reach solid rock. 
REMARKS. 
From a consideration of the fossils found in the Shoot Rough Road 
excavations it seems probable that a local shaley representative of the 
Lingula Flags has been touched, and that the upper limit of the Para- 
doxides division has been reached. Shale with Dictyonema,’ which 
may be of Tremadoc age, is known to occur within a horizontal distance 
of 200 yards north of the sections, and may be nearer, and in 1901 the 
Upper Lingula Flags species, Orthis lenticularis, Wahl, was collected by 
the Rev. W. M. D. La Touche and myself from a calcareous nodule in 
shale within 70 yards in the same direction.” 
It therefore seems very desirable to extend the excavations across the 
intervening ground, so as to establish, if possible, the local sequence of 
the middle ‘and upper divisions of the Cambrian rocks. 
The lower limit of the middle division and the upper surface (probably 
eroded) of the lower division have already been fixed within a few inches 
(see previous report *). It is anticipated that further excavations at other 
spots in the Comley area may throw additional light upon the details of 
the zones of the middle and lower divisions and upon the nature of the 
base of the latter, which was only approximately indicated in Excavation 
No. 4 of 1907. 
I have to acknowledge the very kind response made by Dr. C. A. 
Matley to my request for help with the brachiopods, who tells me that 
his determinations must be regarded as provisional. In the lists of 
fossils I have placed his identifications and remarks within quotation 
marks. 
I am also again indebted to Mr. Philip Lake for assistance in the 
determinations of the trilobités.
