INFERIOR OOLITE : CHIPPING NORTON LIMESTONE. 151 
obtained Ammonites Parkinsoni ; and from higher beds, species 
identified as A. arbustigerus and A. bullatus ; but the occurrence 
of the two last-named species is not accepted by Messrs. Sharman 
and Newton, who have recently examined the specimens. They 
recognize only the species noted below. 
The following fossils have been obtained by Mr. Windoes from 
the Chipping Norton Limestone* : 
Strophodus. 
Ammonites (near to) Bakeriae. 
fuscus. 
Parkinsoni. 
var. dorsetensis, 
Actaeonina. 
Ceritella. 
Cerithium limasforme ? 
Littorina Phillipsi. 
Monodonta. 
Natica canaliculata. 
Nerinaea. 
Nerita rugosa ? 
Patella. 
Pleurotomaria. 
Trochotonaa. 
Astarte. 
Avicula. 
Ceromya undulata. 
Corbis. 
Gervillia pernoides. 
Leda lachryma. 
Lima cardiiformis. 
Modiola furcata. 
*- imbricata. 
Myacites. 
Nucula. 
Opis similis. 
Pecten retiferus. 
So-werbya Woodwardi. 
Trigonia Painci. 
producta. 
v-costata. 
Terebratula maxillata. 
. Phillipsi. 
Holectypus depressus. 
Pseudodiadema depressum. 
In places near Langton Bridge, as remarked by Mr. Beesley, 
the upper part of the Chipping Norton Limestone had the 
appearance of "old weathered mortar," and this mortar-like 
limestone has yielded obscure plant-remains, and portions of 
Chara ; an identification confirmed by Mr. James Groves, from 
specimens obtained by Mr. Windoes. Mr. Walford has procured 
from the same peculiar bed, Ncrincea Eudesi, &c. 
Stratigraphically we must include the Chipping Norton Lime- 
stone with the Inferior Oolite, although it exhibits evidence that 
would lead us to regard it as forming a passage from that 
formation into the Great Oolite Series. Perhaps we may be 
contented with the view that Inferior Oolite conditions endured 
somewhat longer in this area than was the case elsewhere in the 
south-western counties ; or, in other words, it may be a case, such 
as not unfrequently occurs, where a stratigraphical formation 
trangresses the limits of a zone. 
The Chipping Norton Limestone has been well exposed in 
quarries between Chipping Norton and Churchill ; in the railway- 
cutting west of Langton Bridge, about If miles north of Chipping 
Norton church, and in a quarry to the north of the cutting ; in 
another (Padley's) quarry, east of Chipping Norton, an opening 
known as the " Cetiosaurus quarry " (see p. 327) ; and on the 
Burford Road, south-east of the Toll Gate near Chipping Norton. 
At Langton Bridge, the top-bed of the Limestone, winch contains 
fragments of shells and Echini, and quartz grains, is considered 
by Mr. Beesley to exactly resemble the material of the so-called
