the beaches near Abermennyferry in the isle, Gnaphalium 

 marinum [Diotis maritima, Cass.,] and a kind of Leu- 

 cojum [MattJdola sinuata, R. Br.,] both elegant plants. 

 We found on the sea-shores, near Llandwyn, a pretty 

 shell covered with prickles or bristles,* which the Welch 

 call mermaids heads ; abundance of them are thrown up 

 there, all along the sands towards the /return. Upon the 

 coasts of Llandwyn are found a pretty small kind of 

 Concha venerece striatce ; on all the shores hereabout are 

 cast up elegant small CocUece neatly coloured. We 

 lodged at Carnarvon Saturday and Sunday, May the 

 24th and 25th. Here also I found that species of gera- 

 nium [JEr odium 7naritimum, Sw.] mentioned in Prest- 

 holm. Near Carnarvon remain still some ruins of an old 

 town, which the Welch call Caer-Segon, i. e. Segontium 

 of the ancients ; there is a little chapel, with a well close 

 by it, dedicated both to St. Elyn, as is also the river fast 

 by, called the Saint's River ; these are about a quarter of 

 a mile south of the town. There is a chapel of ease in 

 Carnarvon, close to the town wall; the parish church is 

 half a mile out of town, whereabout old Segontium 

 stood. We were told a legend of one St. Byno, who 

 lived at Clenogvaur, and was wont to foot it four miles in 

 the night to Llaynhayrne, and there, on a stone in the 

 midst of a river, to say his prayers ; whereon they show 

 you still the prints of his knees ; his man, out of 

 curiosity, followed him once to the place, to see and 

 observe what he did. The saint coming from his prayers 

 and espying a man, not knowing who it was, prayed that 

 if he came with a good intent, he might receive the good 

 he came for, and might suffer no damage ; but if he had 

 any ill design, that some example might be shown upon 

 him ; whereupon presently there came forth wild beasts 

 and tore him in pieces. Afterwards, the saint perceiving 

 it was his own servant, was very sorry, gathering up his 

 bones, and praying, he set bone to bone, and hmb to 



* Now well known to be the Echinus.
