Dinosauria — Ceratosaurus and Compsognathus. 
downwards and forwards, and unites with its fellow in a long 
bony symphysis, which generally extends up the anterior face 
of the two bones, giving them the shape of an elongated letter Y, 
when seen from the front. The pubis and ischium are com- 
paratively short and slender. The astragalus , or “ ankle-bone,” 
usually fits closely to the tibia, and frequently gives off a long 
flattened process which is applied closely to the anterior face of 
the latter bone, resembling in this respect the free condition of 
these two bones in the young of Ratite birds before the 
anchylosis of the astragalus with the tibia has taken place. 
The metatarsals are elongated and the feet digitigrade. In 
the manus (hand), the number of digits varies from four to 
five, while in the pes (foot), there may be either three or five. 
The terminal phalangeals in all cases have curved claws, which 
in the manus are very long and prehensile, evidently well 
adapted for seizing and holding living prey. 
The skeleton of a small Dinosaur, of which a beautiful Compsogna- 
cast may be seen in Table-case No. 9, the original being * 
preserved at Munich, named Compsognathus longipes , has ^g" casc ’ 
been found entire in the Lithographic stone of Solenhofen. 
From the relative proportions of its limbs we cannot but con- 
clude that it must have “hopped (like a Jerboa), or walked in 
a n ere ct or semi -erect position, after the manner of a bird, to 
which its long neck, slight head, and small anterior limbs must 
have o-iven it an extraordinary resemblance.” (Huxley.)
