STRATA OF JAVA. '^O 



iu a too imperfect state of preservation to permit my for- 

 ming a definite judgment on the point in question, as I 

 am moreover not possessed of sufficient recent material 

 for comparison. 



8. Clypeasfer' humitis Ag. is represented by spe- 

 cimens, partly beautifully preserved, amongst the Javanese 

 fossils. It was described by Herklots as CI. latus (1. c. 

 pag. 6, tab. 2, fig. 1). 



Echinanthus profundus d'Arch et Haime (Description 

 des anim. foss. de I'lnde pag. 207) is indoubtedly identi- 

 cal with this species , as the character , by which they are 

 said to be distinguished: »ses bords plus minces et ses petals 

 plus arrondis inferieurement et completement fermes" are 

 easily found as varieties among the specimens of CI. humilis. 



9. Echinanthus testudinurius Gray. The fossil 

 which Herklots described as Clypeaster tumescens (I.e. pag. 7, tab. 

 2 , fig. 2) does not show the slightest difference, by which 

 it may be distinguished from this recent species inhabiting 

 the Indian Ocean, and of which the Leyden Museum also 

 possesses specimens from Timor. Nevertheless the confir- 

 mation of ray diagnosis by the aid of better preserved 

 specimens seems desirable. 



According to Duncan (Quart. Journ. Geolog. Soc. London 

 1877 XXXIII p. 46 u. 65) this fossil is also found in 

 the tertiary strata of Australia, which is however denied 

 by Mc. Coy, who describes the Australian fossil as CI. 

 gippslandicus (Prodromus of the Palaeontology of Victoria 

 Dec. VI. tab. LIX). 



10. Echinolainpas oviforntis Ag. Probably iden- 

 tical with E. subangidata Herkl. (1. c. pag. 10 , tab. 3, fig. 4). 

 The state of preservation , however , does not allow of a 

 definite judgment, nor whether Nucleolites minutus Herkl. 

 (1. c. pag. 10, tab. 5, fig. 8) must be regarded as the young 

 stage of this species. The name Nucleolites can not be 

 retained for this fossil. 



d'Archiac et Haime have described from the tertiary 

 strata of India E. lacquemonti , which is said to be distin-
