 Doubtful species. 



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

 Gray's- genus Fidenaa, 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 

 as " not good state, lost the pedunculated arms. Shell ? or 

 none." I copy an original figure in H. A. Adams' Genera.
