FISH TEETH AND SPINES FROM BRISTOL DISTRICT. 
43 
matrix shows were derived from the Laminosa-dolomite. Fish 
remains are equally uncommon in the Dibiinophyllum beds 
(horizon D), but the University Collej^e collection contains one 
specimen of CopoduSy three of Psephodus magtms, and one 
of ? Tomodus convexus from these beds, and the Bristol Museum 
contains a specimen of Psephodus magnus from the same beds, 
probably the upper part. 
The University College collection also contains a tooth of Psephodus 
magnus^ and another of Psephodus loevissimus from the Bryozoa 
bed'^ (horizon A) of the Avon section. 
BURRINGTON. 
It is remarkable what a small amount of fish teeth have been found 
in this tine section. The “ Palate bed'' of the Avon section if present 
at all is not exposed, and though the Fish bed" has been recognised 
it is far from rich. The University College collection contains a tooth 
of Helodus sp. and one of Tomodus sp. from the Bryozoa bed" 
(horizon A), and Dr. Vaughan has collected Psammodus rugosus and a 
spine of Ctenacanthus from the “ Fish bed" (horizon Z^). Mr. W. H. 
Wickes has a tooth of Helodus turgidus from the same horizon, and a 
second Helodus tooth from lower beds (Z^). 
SODBURY. 
The “ Palate bed" is well marked, and a fair number of teeth of 
Psephodus Icevissimus have been found in it. 
WICKWAR. 
A spine of Ctenacanthus has been recently found in the more 
southerly of the two quarries, 300 yards W. of the Rectory, the horizon 
being that of the “ Fish bed" of the Avon section. 
WESTON-SUPER-MARE DISTRICT. 
A tooth of Helodus turgidus was found in the Milton road quarry 
(horizon C), and several teeth of Psephodus magnus have occurred in 
the Z^ beds of Swallow cliff. 
PORTISHEAD DISTRICT. 
The upper part of Z^ is exposed in the quarry in Weston big wood, 
and teeth were formerly to be obtained from the quarrymen there. 
Unfortunately no record has been kept of the species found except 
that Prof. Lloyd Morgan records^ finding a spine of Oracanthus h'ere. 
Mr. W. H. Wickes has a tooth of Psephodus from the beds 
exposed on the shore S. of Battery Point.
