Dr. Sutherland followed the margin of the strait to its north- 

 eastern angle in lat. 7^° 20', and Capt. Stewart continued along the 

 shore until he reached the new Queen's Channel, long. 97°. Along 

 the whole coast the same limestone rocks were visible ; and from its 

 peculiar uniform castellated appearance, it could be traced by the eye 

 to extend still further up the sides of that inlet. In the mean- 

 time Capt. Penny and his crew were exploring the islands which 

 separate this channel from the Wellington Strait ; and both in 

 Hamilton Island and Deans Dundas Island abundance of fossils were 

 seen. The necessity of abandoning their boat prevented their bringing 

 them away ; but one of the seamen, James Knox, contrived to roll 

 up a Trilobite and a Bellerophon in the corner of his shirt, and bring 

 them back to Dr. Sutherland. They were from Dundas Island, in 

 lat. 76° 15', the most northerly point of the New Continent from 

 whence fossils have been brought. One of them is the 



Encrinurus Isevis, before mentioned ; the other, 



46. Bellerophon nautarum, n. sp. (/. c. pi. 5. fig. 20). So named 



in honour of the crews of the ' Lady Franklin ' and ' Sophia.'
