140 Dr. Scouler on some fossil Crustacea [Feb. 



inferior in size to the species which formerly existed in the 

 same places ; and the same remark applies to the fishes. 



Besides the remains already described, the examination 

 of other places afforded different specimens. Although 

 unsuccessful in the search for the teeth of fishes, others 

 were more fortunate. Two teeth of Sauroid fishes were 

 found by my young friends the Masters Brown, in shale 

 at the sandstone quarry near Woodside. The sandstone is 

 covered by alternate beds of sandstone, coal, and shale, and 

 it is in the last named substance that the teeth are found. 

 Encouraged by the success of the gentlemen I have men- 

 tioned, I repeatedly examined the shale of this place, but 

 unsuccessfully, for the only specimen which I procured was 

 the spine of the fin of some fish resembling the bony spine 

 of the dorsal and pectoral fins of some Siluri. It was about 

 4 inches in length. A sauroid tooth was also found in the 

 neighbourhood of Campsie, and presented to the Ander- 

 sonian Museum at Glasgow by Mr. Graham. 



Remains of fishes also occur in the parish of East Kilbride, 

 as had long ago been indicated by Ure in his interesting 

 work. In that parish the upper part of the limestone is 

 extremely rich in the remains of marine animals, such as 

 entrochi, ammonites, productae, reteporae, turbinoliae, Sfc. In 

 one place whose name I do not know, there are a number 

 of beds of clay and shale resting upon the carboniferous 

 limestone, which afford a different kind of organic remains. 

 In this situation we find the remains of fishes, coprolites, 

 and Crustacea. The coprolites are as distinct as those 

 figured by Mr. Mantel from specimens found in the chalk, 

 and are spirally twisted as is the case in those which are 

 observed in more recent formations. 



No teeth were found, but one bone of a fish was procured 

 which I have communicated to M. Agassiz, whose labours 

 have so much illustrated this branch of natural history.
