interest those who remember Dr. Hanitsch's researches 

 regarding the pineal eye. Mr. Newton writes, describing 

 the skull of Gordonia Traquari — " Between the anterior 

 " part of the parietal crests is the large pineal fossa which, 

 " as can be seen in the right half of the skull, forms a very 

 " distinct cup opening below into the brain cavity. The 

 " deep cup-like form of the pineal fossa is probably an 

 " indication that it lodged a well-developed eye." The 

 Labyrinthodons have a well-marked pineal fossa ; the 

 pineal eye is present in Sphenodon, but it has not been 

 detected in Hyperodapedon. 



Of the form of the limbs something is known, though 

 not of the extremities. I do not know whether I am right 

 in my conjecture, but I should suppose that the broad 

 humerus would very likely be accompanied by a short-toed 

 broad foot. 



Another very remarkable form has been figured from 

 Elgin, to which Mr. Newton has given the name Elginia 

 Mirabilis ; * this he considers is more allied to Pareiosaurus 

 than to Dicynodon. Of none of the species of Grordonia, 

 nor of Elginia, have the bones of the feet been preserved, 

 and to form an idea of the foot we must refer to their 

 South African relations. The national collection con- 

 tains a nearly complete skeleton, finely mounted, of 

 Pareiosaurus bombidens described by Professor Seeley, 

 and the short broad feet are clearly shown ; and it is quite 

 possible that a rather common form of footprint here may 

 represent an allied animal. The Dicynodon remains at 

 Elgin would represent an animal about the size of a terrier 

 dog. Some years ago I had the honour of reading to this 

 Society a short paper f on a small footprint with short toes 

 bearing strong claws which has been frequently found at
