in our figure. Dr. Leach, however, in his description, 

 says, " extremite presque tronquee, echancree." 



The species inhabits the Mediterranean, and is also 

 found not unfrequently on our coasts. 



Specimens from St. Leonards are in the Hopeian 

 collection at Oxford. We have also obtained it by 

 trawling in Plymouth Harbour at the beginning of 

 February, and have received it from the Rev. A. M. 

 Norman, who has taken it on the coast of Durham. 



The Oxford Museum also possesses a small specimen 

 labelled as having been taken at Plymouth, which \vas 

 considered by Mr. Hope as a distinct species (the MS. 

 name of " Spilota, Hope," in the handwriting of the 

 donor himself, being attached to it), it being dotted all 

 over with small brown spots, arranged at equal distances 

 apart, so that there are about a dozen occurring next the 

 posterior margin of each segment.
