Buck man. A long globose Terebratula , belonging to the 
sjjhoer old alls group, from the Dogger of Beak, Yorkshire coast, 
where it was found by S. Chadwick, F.G.S. 
(15) Terebrafula trilineata , Young and Bird. Several 
specimens, with the test preserved, have been found by Mr. 
S. Chadwick, in the Dogger of the Peak, Yorkshire coast. This 
shell requires careful study. 
(16) Mr. E. T. Newton, F.Gr.S., sent me for determination 
a terebratula, which had been found by the Geological Survey 
at Silpho near Hackness, Scarbro’, from the Middle Calcareous 
Grit. The specimen is a crushed internal cast, but I have been 
able to determine it as Terebrafula bisuffarcinata , Zieten. 
This species is very variable in shape. It has a large foramen, 
and the internal cast shows that if had a short loop, the front 
had a wide fold, which in this specimen has been nearly 
obliterated by pressure. It is new to Yorkshire, but has been 
found in the zone of Ammonites perarmatus at Braambury 
Hill, Sutherlandshire, Scotland. It is a common fossil in the 
Weisser Jura of Germany. 
Mr. Fox-Strangways. F.G.S., sent me the following note■ 
“ The Terebratula mentioned was from the Middle Calcareous 
Grit , and consequently I should be inclined to refer it to the 
zone of Ammonites plicatilis , although these sandy beds contain 
so poor a fauna that there is not much evidence as to what 
they should be referred, Mr. Hudleston is inclined to place the 
topmost band of the Lower Limestones in this zone, and 
consequently these beds which lie above it must also be referred 
there.’ ’ 
The total number of species and named varieties of Oolitic 
Brachiopoda, which occur in Yorkshire, is 43; of which 9 
occur in the Dogger beds of the Inferior Oolite; 4 in the 
Millepore series and its inland equivalents ; 2 in the Scarbro’ 
Limestone; 7 in the Cornbrash and Avicula shales; 3 in the 
Kelloway Bock; 2 in the Oxford clay; 8 in the Lower 
Calcareous grit and Passage beds ; 1 in the Coralline Oolite ; 
5 in the Coral rag ; and 5 in the Kimmeridge clay. The 
number of species in each genus is : Lingula , 2 species ; Discina , 
3; Thecidtum , 1; Terebratula , 10; Waldheimia , 15 ; Rhynchonella ,
