Mr. J. Lycett on a new species of Pteroceras. 119 



known example. /\ If'rif/htii in its perfect state would seem to 

 have had five encircling itrise ; theRe are partially visible upon the 

 inferior surface of our specimen, the coarseness of the oolitic de- 

 posit in which they occur being unfavourable to the preservation 

 of any delicate sculpture. The surface of the body-whorl near 

 to the labial expansion n much covered up by adherent oysters, 

 but it appears to have been destitute of any encircling carina?. 



The general figure has some resemblance to the Pteroceras 

 ponti of D'Orbigny, but that species has upwards of six digita- 

 tions and as many costse upon the body-whorl. The cast figured 

 by Gold fuss under the name of Buccinum antiquorum from the 

 doloinitic oolite of Bavaria, may possibly belong to our species, or 

 otherwise to an allied form of the same genus. The remarkable 

 specimen here described is in the collection of Dr. Wright of 

 Cheltenham, to whom it is respectfully dedicated. 



Locality. Minchinhampton : common to the varied fossil fauna, 

 to which it is an important addition.
