position is unknown. Some of the specimens found in tlie 
Terebratula- bed (C. b, fig. 3) may belong to this species. 
Terebratula trilineata , Y. and B. This species occurs at Blue 
Wyke (C. b, fig. 3). Also in fallen blocks along the coast as 
Casts in a chocolate-coloured matrix. It is found in the shelly 
bed of the Dogger at Crag Hall (D. z, fig. 4). Also at Bose- 
dale, Grrosmont, Grlaizedale, &c. This species appears to be 
closely allied to Terebratula Haresfieldensis, -Day., which occurs 
in the Midford sands of Haresfield and Frocester in Grlostershire. 
Rhynchonella subobsoletci, Day. Occurs in the Dogger proper. 
(D. fig. 3). 
Terebratula submcixillata , Day. There is a fine specimen in 
the York Museum from the Whitwell limestone; we also haye 
found it in this quarry. There are some crushed specimens in 
the York Museum which probably belong to this species, they 
are supposed to have been found in the blue marly shales of 
Grristhorpe, where Mr. Hudleston has obtained a specimen which 
is also crushed. These marly shales belong to the Scarborough 
Limestone series. 
Terebratula bullata, Sow. This is a form intermediate bet'ween 
T. globatci and T. spliceroiclalis. It occurs in the blue sandy 
limestone (6, fig. 7,) a little above the Whitwell Oolite at 
Crambeck. 
Rhynchonella spinosa , Sow., var., occurs in the same blue 
limestone. 
Rhynchonella Crossii , Walk., is common in the Lincolnshire 
Limestones of Brough, near Hull, crushed specimens of a 
Terebratula , probably T. bullata, occur in the same stone. 
Waldheimia lagenalis, Schlot. This species is common in the 
Cornbrasli of Scarborough, it also occurs in the Avicula- shales. 
Waldheimia obovata, Sow. Is very abundant in the Cornbrasli. 
Besides the typical variety, a narrow form occurs which has 
been confounded with W. digona , from which it is quite distinct; 
the curious rhomboidal globose variety also occurs. 
Terebratula intermedia, Sow., as a small variety. 
Terebratula Bentleyi, Dav. This rare species has been found 
by Mr. Leckenby in the Cornbrasli on the north side of Scar¬ 
borough. i
