„ cf. discus Waag. 
Aspidites spitiensis Krafft. 
ensanus Krafft. 
,, crassus Krafft. 
Koninckites Hmjdeni Krafft. 
alterammonoides Krafft. 
To those apecies of ammonites must be added : — 
Xenodiscus radians Waag. 
Ulangensis v. Krafft. 
Hedenstroemia Ulangensis v. Krafft, tlie most primitive species 
of this genus, together witli a new genus, nearly allied to 
Hedenstroemia, but holding a position intermediate between it 
and Psendosageceras in the arrangement of its sutural line. 
Of NaiUiloidea one species only — Grypoceras lilangense Krafft — is at 
present known. 
Lithologically the Ophiceras beds and tht^ Meekoceras beds are 
connected so intimately, that A. v. Kraft't and H. Hayden did not 
succeed in keeping separate the fossils which they collected in some of 
their detailed sections. Those two faunistic subdivisions should 
therefore not be taken as sharply defined stratigraphical horizons of 
paramount importance. The two faunse are, it is true, as a whole 
distinct, but it must be understood that we cannot yet say anything 
definite about their affinities, the original layer of a considerable 
number of species, which are perhaps common to both of them, re- 
maining uncertain.' 
1 There are not less tlian tliirteen species of douhlful stratigrapliical position, 
namely : — 
Meekoceras horeale Dien. 
,, cf. radiosum Waag. 
dubiurn Kraft't. 
„ kyokticuni Kraft't. 
Aspidites Vidarhha Dien. 
Proptychites typicns Krafift. 
,, sp. ind. aff. typico. 
All of these certainly helong to the lower division of the Lower Trias, but the 
particular horizon in which they have tlieir hal)itat, is not known, 
( 219 ) 
Xenodiscus rigidus Dien. 
,, rotida Waag. 
„ cf. plicosus Waag. 
Nannites hindostaniis Dien.
