S. PENARES, Gray. PI. 67, fig. 244. This species is the type of 

 Gray's genus Fidenas. which does not seem to possess any dis- 

 tinctive characters to separate it generically from Sepiola, except 

 that the suckers are long-peduncled, and the peduncles are con- 

 stricted on the upper part. The specimen, in spirits, is described 

 u not good state 1 , lost the pedunculated arms. Shell ? or
