REVISION OF THE FOSSIL ECHINI FROM THE 

 TERTIARY STRATA OF JAVA. 



BY 



Dr. K. MARTIN. 



PROFESSOR OF GEOLOGY, 



Marcli 1880. 



Ill the year 1854 J. A. Herklots published a descrip- 

 tion of the fossil Echini, which had been found by Jung- 

 huhn in the tertiary strata of Java, in the fourth part of 

 a publication, entitled «Fossiles de Java." I have been 

 occupied in working out the other groups of animals from 

 these deposits, which by the death of Herklots was left 

 unachieved. The results of my investigations have been 

 embodied in the work entitled »Die Tertiarschichteii auf 

 Java", the palaeontological part of which has appeared a short 

 time ago. I succeeded in demonstrating, that a conside- 

 rable percentage of these fossils are yet represented in the 

 recent fauna of the Indian Ocean, and for this reason 

 I was astonished to find , that all the Echini , with only 

 a single exception , were described by Herklots as new 

 species. This induced me to undertake a revision of these 

 species , which has indeed led me to results entirely diffe- 

 rent from his. Not only a lai'ge number, but by far the 

 majority of all the wellpreserved individuals could be iden- 

 tified with species , which are still living in the Indian 

 Ocean.
