 Kothliegende.

 Footprints similar to Sub-type H26 (fig. 17) are known only from 

 the Kothliegende of Silesia and Moravia. They have been named

by Prof. Pabst I. x^acliydactiilum {umjulatum) (figs. 18 & 19). His 

 description of them in his memoir is as follows : — 



' Footprints five-toed. Toes short, conspicuously

Of the natural size). ^^ch foot has a broad ball with rounded, weak, 



bluntly-marked ends. The width of the foot is 



from 1 to 1-5 cm. greater than their length,' 





In every particular in the above de- 

 scription there is strict agreement be- 

 tween the Hamstead examples of H26 and 

 Prof. Pabst's species ; hence I feel no 

 hesitation in classing the Hamstead type 

 H26 as I. pachydactylum (ungidatum). 



Type H3. IcHxiu]M jBRACHrDACTYLTjM (Pabst). One specimen in 

 relief (cast). (See figs. 20 & 21, p. 667.) 



H3 includes footprints with five toes, and with u somewhat 

 massively developed ball. The toes are short, weak, thickened 

 somewhat towards the tips, yet with the ends sharp. The fourth 

 is the longest. The length of the footprint is about equal to the 

 width. The print of the fore foot is only slightly smaller than 

 that of the hind foot. The fore footprint in the specimen is not 

 clearly marked, and cannot be accurately measured.
