Description. — Subplatyleptogyral, latumbilicate, costate. 



Remarks. — Further investigation has shown that the figured example has really 

 a hollow carina — it is septicarinate. Therefore it must be removed from association 

 with Gra,mmoceras toarciense and brought into connection with the Struchnanni 

 series. The term " toarcense-striatulum " was intended to be merely descriptive, 

 not a definite specific title. The jjlacing of " S. Buckman " after it was an editorial 

 " correction " of a supposed omission. 



Locality and Stratum. — Gloucestershire: Little Sodbury, Bed 18, p. 165. 

 (? Batcombe, near Shepton Mallet, Upper Lias, but specimen not yet sufficiently 

 freed from matrix).
