Quensfedft. The pelvis is described and restored. Zanclodon has 

 the cervical vertebree relatively long, as compared with Megnlosaurus, 

 and small as compared with the dorsal vertebrfe, which have the 

 same Teleosauroid mode of union with the neural arch as is seen in 

 Streptospondylus and Massospondijhis. The sternum, of Pleininger, 

 is the right and left pubic bones ; but there is much the same 

 difference in the proximal articular ends of those bones in the fossils 

 at Stuttgart and Tubingen, as distinguishes corresponding parts of 

 the pubes in Megalosaurus and Streptospondijlus. The ilium is more 

 like that of PaIa;osaurus and Dimodosmirus. The limb-bones and 

 digits are most like those of Dimodosatirns, but the teeth resemble 

 Falceosaums, Eiiskelesaiirus, Megalosaurus, and Streptospondylus. 



Part 5 discusses Tliecodontosaurus and Palavsaurvs upon evidence 

 from the Dolomitic Conglomerate in the Bristol Museum. An 

 attempt is made to separate the remains into those referable to 

 Tliecodontosaurus and those belonging to Pnlaosaurus. The latter is 

 represented by dorsal and caudal vertebras, a scapular arch, humerus, 

 ulna (?), metacarpals, ilium, femur, tibia, fibula, metatarsals, and 

 pliiilanges. These portions of the skeleton are described. There is 

 throughout a strong resemblance to Zanclodon and other Triassic 

 types. A new type of ilium, and the humerus originally figured 

 are referred to Thecodontosaiirus. 



Part 6 gives an account of the South African genus Massospon- 

 dylus. It is based partly upon the collection from Beaucherf, in the 

 Museum of the Koyal College of Surgeons, referred to M. carinatus; 

 and partly upon a collection from the Telle Eiver, obtained by 

 Mr. Alfred Brown, of Aliwal North, referred to M. Browni. The 

 former is represented by cervical, dorsal, sacral, and caudal vertebra?; 

 ilium, ischium, and pubis; femur, tibia; humerus, metatarsals, and 

 phalanges. The latter is known from cervical, dorsal, and caudal 

 vertebrae, femur, metatarsals, and bones of the digits. The affinities 

 with Zanclodon are, in some parts of the skeleton, stronger than with 

 Euslcelesaurvs. 



Part 7 gives an account of Enslcelesaurus Browni, partly based 

 upon materials obtained by Mr. Alfred Brown from Barnards Spruit, 

 Aliwal North, and partly on specimens collected by the author, with 

 Dr. W. G. Atherstone, Mr. T. Bain, and Mr. Alfred Brown, at the 

 Kraai River. The former series comprises the maxillary bone and 

 teeth, vertebrae, pubis, femur, tibia and fibula, phalanges, chevron 

 bone and rib. The latter includes a cervical vertebra and rib, and 

 the lower jaw. The teeth are stronger than those of Teratosaurus, 

 or any known Megalosaurian. The anterior part of the head was 

 compressed from side to side, and the head in size and form like 

 Megalosaurus, so far as preserved. The pubis is twisted as in 

 Staganolepis and Massospondylus, with a notch instead of a foramen 

 at the pi'oximal end, as in those genera ; and it expands distally 

 after the pattern of Zanclodon. The chevron bones are exceptionally 

 long, and the tail appears to have been greatly elongated. The 

 femur is intermediate between Alegalosaurus and PaltEosanrus, but 

 most resembles Zanclodon and Massospondylus. The tibia in its
