siderably stouter than the fibula. The foot is crushed laterally, 

 but the bones of the tarsus can be fairly satisfactorilj' made out. 

 There is a large broad bone which articulates with both the tibia 

 and fibula, and which is probably composed of the anchjdosed 

 tibiale, intermedium and centrale. To the oxTter side of this large 

 tarsal bone is a smaller bone, which is probably the fibulare. The 

 distal row of tarsal bones is made up of a small first tarsale, a 

 somewhat larger second tarsale, a third small tarsale, and a fourth 

 very large tarsale. There is no evidence in the specimen of a fifth 

 tarsale. All the five metatarsals are well preserved. The fourth 

 is the longest ; the third a little shorter, and the second shorter 

 than the third. The first is much shorter than the second, and 

 the fifth considerably shorter than the first. The fourth toe has 

 five phalanges. There is no specialisation of the fifth metatarsal 

 such as is seen in SpJienodon, and the tarsus differs from that of 

 Sphenodon in having the fibulare distinct and in having the first 

 and second tarsalia well developed. It would thus appear that 

 whatever be the position of Saurosternon it is not closely allied 

 to Sphenodon, and as far as the tarsus is concerned it is distinctly 

 more primitive. 



On a new South African Labyrinthodont ( Gyclotosaurus 

 Alhertyni). By R. Beoom, M.D., &c. 



In the collection of Mr. Alfred Brown of Aliwal North, there 

 are numerous teeth, small skull fragments and portions of 

 vertebrae of a Lahyrinthodont of much larger size than 

 Rhytidosteus. In the neighbourhood of Burghersdorp I discovered 

 a large interclavicle and other fragments of probably the same
