OBSERVATIONS 
The original specimen cannot be identified ; or it has been lost. The example now depic- 
ted is a topotype — one of the specimens obtained by my father from the same place as the 
type, and probably it is one of the specimens which be had before him when he founded 
the species — so that it may almost be regarded as a metatype. 
Properly speaking no description of the species was given in the text. That may be stated 
thus : 
Numerous nearly quadrate whorls, barely in contact. Periphery bears a strong carina, 
bordered by narrow furrows. Smooth stage (miserabilis-slage) in youth, to about 16mm 
diameter. Then the costæ gradually increase in strength, are slightly reclinate, straight, 
narrow, sharp ; they are parvi-tuberculate on outer edge, and sharply turned forwards on 
periphery. 
Genus. Arnioceras, vide Hyatt (1889. — Gen. Arietidæ ; Smiths. Contrib., No 673, p. 169). 
Locality and Horizon. The records may be thus interpreted : — Railway cuttings in the Vale 
of Gloucester, perhaps Coldpool about midway between Cheltenham and Churchdown, 
Lower Lias (Sinemurian), semicostatus-zone. So far as is known the localities Bredon, and 
Lansdown (Cheltenham) contain only beds higher than those to which Arniocerata belong. 
These records, like that of Am. crenata (J. Buckman, loc. cit, p. 43) the name first thought 
of for À. Bodleyi, probably refer to species which really belong to another genus. 
My thanks are due to Mr. J. W. Tutcher, a Bristol geologist, for the excellent photo- 
graphs of the specimen now reproduced.
