Williani Yarrellj Es.q. in tne Chair. 



A letter was read, adtlressed to the Society by W. WilIiamson, 

 Esq., dated Scarborougli, July 2, 1833. It contained a full de- 

 scription of a specimen of the garrulous Roller, Coracias garrula, 

 Linn., which vvas sliot in the previous week in a limestone quarry 

 near that place. The des>cription was that of a female in nearly adult 

 plumage. 



A specimen wa8 exhibited of the Irish Ilare, recently presented 

 to the Society by Mr. Yanell, who pointed out tbe characters by 

 which itis distinguished fiom the commori Hare of England and the 

 Continent of Europe. Its head is shorter and more rounded; its 

 ears stiil shorter than its head; and its linibs less Icngthened. 

 The fur also ditfers essentially from that of the common Hare, and 

 is useless as an article of trade. Mr. Yarrell added, that he had 

 lately brought a specimen of it under the notice of the Linnean 

 Society. 



At the reąuestof the Chairman, Dr. Stark exhibited the skeleton 

 of the edible Fi-og, Ratia escideuta, Linn., and stated that this spe- 

 cies is found in the ncighbourhood of Edinburgh, vvhence his speci- 

 men vvas obtained. He pointed out some of the differences between 

 its osseous structure and that of the common Frog, Rana tempo- 

 raria, Linn. 



Dr. Stark also stated that he had obtained in the neighbourhood 

 of Edinburgh specimens of a species of Sticklebaik, Gasterosteus, 

 Linn., not previously knovvn to exi5t in Great Britain. 



In ansvver to a question on the subject, Dr. Stark described the 

 changes produced in the colour of various Fishes, both of fresh and 

 salt water, but especially in Mimioįvs, Leuciscus Phoxinus, Cuv., in 

 consequence of their being kept in vvater contained in vessels of dif- 

 ferent colours ; the tendency of the fish being to assume the colour 

 of the vessel in which it is kept. 



The stomach and ccecum of a Sq7iirrel Monhey, Callithrix xciureus, 

 GeofF., which recently died at the Society 's Gardens, were exhibited. 

 At the request of the Chairman, Mr. Martin read his notes of the 

 dissection of the animal. 



" The length of the body in this individual vvas 10 inches; that of 

 its tail, II-. 



" On opening the (thdomen, the viscera vvere obscrved to occupy 

 theusual situation, and presented nothing remarkable in their gene- 

 ral aspect.
