streams, and a peculiar species. Pennant (British Zoology 

 iii. 405.) says that the par abounds in the Wye in September. 

 Now, the gravelling and skegger disappear in the Taw and 

 the Thames before that period; and Walton says that the 

 latter sometimes grows as large as a herring: therefore the 

 gravelling seems a different fish from the par and skegger; 

 never attaining such a size, and disappearing, that is, mi- 

 grating to the sea, long before September. I found the 

 gravelling in two other rivers in Devonshire ; namely, the 

 Yeo, which empties itself into the Taw at Barnstaple ; and 

 the Exe, near Exeter. 



The history of fish is, partly from the element in which 

 they live, and partly from ichthyology having been less 

 ardently pursued than other branches of natural history, 

 very obscure : and I have communicated these remarks to 

 add my mite to the elucidation of what has always been to 

 me an interesting department. 



Clapton, Nov. 7. 1834. 



Art. VI. Remarks on some Barnacles of the Species hepas anali- 

 fera found floating off St. Adhelms Heady on the Coast of Dorset : , 

 on February 7. 1834. By the Rev. W. B. Clarke, M.A. 



James Blagden, Esq., of Poole, brought me, on Feb. 7. 

 1834, a slice of wood, of about 6 in. by 5 in., with a species 

 of iepas (fig. 2. b.) attached to it; in such numbers, that 

 they have defied calculation. The largest is not more than 

 3 in. long, including the pedicle, which takes up about two 

 thirds of the length. The smallest are so minute as to be 

 microscopic. It appears that the people of one of the Poole 

 pilot-boats found two, of what they denominated "posts," 

 floating off St. Adhelm's Head, in the morning of Feb. 7. 1834, 

 just subsequent to the late tremendous west and south-west 

 gales ; and, perceiving them covered all over with barnacles, 

 they towed them into Poole harbour; from which they were 

 taken ashore at the Hamworthey quay, and there laid aside. 

 Mr. Blagden seeing them, and being struck with the singu- 

 larity of their appearance, stripped off two or three slices of 

 the wood ; which, being very soft, and almost pulpy, was not
