the water, and has convenient hiding-places amongst the 

 aquatic plants, and especially amongst and under the ample 

 leaves of the water lilies (iVymphge a alba L, and 2S/'ilphar 

 advena H, K.), and occasionally it floats stationary on the sur- 

 face of the water, as it were in the manner in which fishes, in 

 slow streams, are, in hot sunny weather, said to sleep. It has 

 increased in size considerably, arta appears very healthy. 

 Mr. Scott has told me, that once [in April or May, 1832] it 

 travelled to near the Free School Lane entrance to the 

 garden; a distance of, perhaps, 150 yards from the water, 

 — possibly in search of a mate. 



These facts prove that this species of tortoise will live in 

 any reservoir of water, like that in the Cambridge Botanic 

 Garden ; and they may, especially if the amount of them is not 

 already well known, promote endeavours to naturalise many 

 individuals of this and other species of aquatic tortoises in 

 similar situations, where they could not fail to be interesting 

 objects to lovers of nature. — X D, sen. 



A young hand ToHoise.^ once kept in a cool green-house in 

 a private garden at Bury St. Edmunds, lost its life by 

 attempting to ascend a tall stone step placed at the threshold 

 inside the entrance door. It fell backwards ; and the con- 

 vexity of its shell was such, or the animal's weakness (for I 

 suspect that it had been but very negligently fed) was such, 

 that it could not apply its feet to the floor to lever itself into 

 its natural position. It was found lying on its back, dead, 

 and with froth at its mouth. — J". Z). 



Fishes. — The Goldfish, mth a double Tail-fin, (VI. 529.)— 

 Another instance of this variation is now living at Mr. Hope's, 

 of Deepdene. — W. Fowler, Dec, 17. 1833. 



Molluscous Animals. — A List of the more rare Species of 

 Shells, which were collected in August, 1833, at Aberdovey, in 

 Merionethshire, — This part of the coast has, I believe, been 

 but little explored by the conchologist. The following species 

 of shells were all found on the sand at Aberdovey, or between 

 that place and Borth. v, r, mean very rare ; r, rare ; f, fre-
