and rough with minute scales. The feet or suckers are, as usual, 

 arranged in five double rows, becoming single occasionally to- 

 wards each end of the body. They are rigid and non-retractile. 

 The tentacles are rather small and plumose. 



This species is more worm-like than most of its congeners. 

 The scales that cover the body, Avhen highly magnified, are seen 

 to be beautifully perforated. (PI. II., Fig. 4.)

In company with my friend, W. H. Brown, of North Shields, 

 I enjoyed, in the past summer, a very pleasant ramble through 

 the wilder parts of Northumberland. All who have been in- 

 terested in our local flora have felt that the hilly tract bounding 

 our county to the west northwards to Cheviot proper had been 

 very imperfectly explored, if indeed ever visited by the botanist. 

 Our attention was to a considerable extent devoted to the 

 Phoenogamous vegetation, and the Alg^e of the route which we 

 traversed. On the present occasion I shall confine myself to 

 notices of some of the more interesting flowering plants which 

 we met with. The genus Hieraciwn was especially kept in view 

 in the upper glens and valleys of our rivers, and, with the as- 

 sistance of my kind friend, the author of the " Monograph of the 

 British Hieracia," I think I am able to record some species as 

 members of our flora, which had not been previously satisfactorily 

 ascertained to be included therein. Another visit to the remote 

 corners of our county is yet required, in order to ascertain the 

 altitudinal range of the commoner species of plants — an object 

 better attained on a second visit than a first, when the general 

 aspect and topography of the country and the peculiarities of its
