Vol. i. p. 439. Genus ANATOMUS. 



The animal of Anatomus or Scisurella has been made known 

 to us by Mr. Lucas Barrett, and its position among the Trochida:. 

 is thus confirmed. The following is his description : " Ten- 

 tacles long, serrate, at the base of which are placed the eyes ; 

 foot furnished with two pointed lappets, and two long, slender, 

 serrated cirrhi on each side. Operculum very thin, ovate, with 

 an obscure, sub-spiral nucleus. No part of the animal was 

 external to the shell. The only living specimen occurred at 

 Hammerfest in forty to sixty fathoms of water. When it was 

 placed in a glass of sea- water it crawled up the side and 

 scraped the glass with its tongue. After immersion in spirit it 

 became inky black." 



Ex. A. crispatus, Fleming, pi. 137, fig. 19.
