IX. On the Genus Peripatus of Guilding. 
The Rev. Mr. Guilding has described this animal as a genus of Mol- 
lusca. Having lately examined a specimen which formed part of Sir 
Hans Sloan’s collection, I am satisfied that it is an Annelide^ as Dr. 
Shaw appears to have considered it. In the Zoological Journal, IV., 278, 
Mr. MacLeay, since the above observations were made, has remarked that 
it is an annulose animal, connecting the Julidae with the Worms amongst 
the Amelalolia. What are the Worms of Mr. MacLeay } It appears rather 
to be the genus which unites the family of Nereidae with the Lumbrici or 
Earth-worms.
