Rev. Mr. Wailes exhibited a specimen of the rare insect Psali- 

 dognathus Friendii, concerning which some discussion followed. 



Mr. Gray read a paper on the formation of angular lines o?i the 

 shells of certain Mollusca. 



A paper was read on the wild Cattle of Chillingham Park^ by 

 J. Hindmarsh. There are in this herd, 25 bulls, 40 cows, and 

 15 steers of various ages. They are beautifully shaped ; have 

 short legs, straight backs, horns of a very fine texture, thin skin, 

 so that some of the bulls appear of a cream color. They have a 

 peculiar cry, more like that of a wild beast than that of ordinary 

 cattle. The eyes, eye-lashes, and tips of the horns alone are black, 

 the muzzle is brown, and the inside of the ears red or brown, 

 and all the rest of the animal white. The author was inclined 

 to consider these animals the survivors of the Caledonian cattle, 

 which undoubtedly extended through the northern provinces of 

 England ; and that, under the protection of the owners at Chil- 

 lingham, they had escaped the general destruction dependent on 

 the advance of civilization. 



Next was read a paper on the production of Vanilta in Europe, 

 by Prof Morren, of Liege. 



Dr. Parnell read a paper on some 7iew ajid rare specimens of 

 British Fishes, viz. Gadus cimbrius, Pagellus acarine, Raia cha- 

 grinea, R. intermedia, R. clavata, Cottus scorpicus, Platessa li- 

 mandoides, P. pala, Mugil chelo, Trigla gurnardus. 



The next paper was by Mr. J. Hancock, on the Falco Island- 

 icus of authors. Mr. H. stated that under this name were con- 

 founded two distinct species. For the Iceland species he retained 

 the name of F. Islandicus ; the other he named, from the coun- 

 try in which it is most abundant, F. GrcBnlandicus. 



Col. Sykes read a paper on a rare animal from South America. 

 It was described by Azara, and called Canis jubatus. It differed 

 from the dog tribe in its nocturnal and solitary habits ; its tail 

 was thicker, more bushy, head flatter, eyes smaller, nose sharper, 

 and the whole animal more bulky than the dog tribe. If it dif- 

 fered from the dog, it differed more from the fox and wolf, and he 

 proposed to refer it to the genus Hyeena. 



The next paper was on Vegetable Monstrosities, by Rev. W. 

 Hincks. These he distributed into five classes. 1. Cases of co- 

 herence and adherence of parts not usually united, or of separation 

 of those which are ordinarily connected. 3. Anomalies depend-
