CORNCERES QUARRY. 49 



quest of its president, Sir D. Brewster, furnished a 

 paper on Cilia. If he commenced with Leeuwenhoek's 

 " Continued io Arcanorum Natures," and traced the 

 history of his subject down to the discoveries of 

 Sharpey and Grant, supplementing them with his own 

 work and illustrations, he could not fail to please and 

 deeply interest a body of men who lived on the shores 

 of a bay rich in ciliated organisms. 



On November 30, 1838, Goodsir described certain 

 fossil fishes from the limestone and slates of Corn- 

 ceres quarry near to Anstruther. He stated that in 

 addition to teeth of the Megalichihys and spiral Cop- 

 rolites, he had found a number of entire specimens and 

 detached scales of fishes referable to the Lepidoides 

 of the Ganoid order of Agassiz ; these latter speci- 

 mens contained five species referable to two genera- 

 one of these genera was closely allied to Palceoniscus, 

 lull differed from it in wanting the scaling or false 

 rays along the anterior rays of the anal and dorsal fins, 

 and on the upper and lower rays of the caudal, and 

 also in the anal and dorsal fins being almost opposite 

 to one another near the tail, as in Dipterus. To this 

 genus Goodsir gave the provisional name Catopterus, 

 at one time applied by Agassi/ to the Dipterus of 

 Sedgwick and Murcliison, but afterwards rejected by 

 himself; be considered three of the quarry specimens 

 to belong to it. The second genus he viewed as inter- 

 mediate between Ambh/pterus and Eurynotus, ap- 

 proaching the former in the form of the body, and the 

 latter in the character of the dorsal fin, and differing
