to refer to a former paper ^ for the phylogenetic value of the 

 ascending process. In opposition to what is known of Allosaurus 

 and Megalosaui'iis, there are in Streptospondylus in each foot four 

 well-developed metatarsal bones, each bearing well-developed toes 

 armed with claws. The claws show the carnivorous pattern. 



With the superior crest of the ilium Mr. Parker's nearly complete 

 Streptospondylus stood about 4 ft. 9 in. from the ground, and the 

 Paris specimen may have been 6 feet in height ; the total length of 

 these two animals was probably 20 and 27 feet. Megalosaurus, we 

 may assume, may have attained a maximum length of 30 feet. 



Plate XV accompanying this notice gives a reconstruction of 

 Streptospondylus as based on the study of Mr. J. Parker's fossil, 

 and Miss A. B. Woodward has had the great kindness to make 

 this drawing according to my directions. The large skull, the 

 feeble but flexible neck, the weak anterior and powerful posterior 

 limbs are well shown. 



The principal diiferences of Streptospondylus and other Theropoda 

 have already been pointed out in different parts of this paper ; here 

 I wish only to refer once more to the Sauropod-like build of the 

 vertebral column. That the Sauropoda descended from bipedal 

 Saurischia I intend to discuss upon some other occasion. The 

 specific name of the only kind of Streptospondylus known till now is 

 Strept. Cuvieri (H. v. Meyer) ; the horizons at which the genus 

 occurs are the Callovian in France and the Oxford Clay at Oxford in 

 England.

II. — An Account of some Marine Fossils contained in Lime- 

 stone Nodules found on the Mekran Beach, off the 

 Ormara Headland, Baluchistan.

THEOUGH the kindness of Miss Caroline Birley, of Kensington, 

 I have been privileged to examine a collection of fossil marine 

 shells and other organisms in her possession, which occur in drab- 

 coloured, gritty, and siliceous limestone nodules picked up on the 

 beach off the Ormara Headland, facing the Mekran or Baluchistan 

 coast, 130 miles west of Karachi, by Mr. F. W. Townsend, chief 

 executive officer of the Submarine Telegraph Service in the North 

 Indian Ocean. 



So far as the present specimens demonstrate, the nodules vary 

 in size from two to about four inches in diameter, many of them 

 being as round as a ball with perfectly even surfaces, to which are
