a rugged and denuded surface of tlie carboniferous quartzite, it must be admitted 
that on this account alone the shales (Kuling shales of Stoliczka) must be included 
amongst the Triassic group. These shales resemble the Wei'fen beds of the Alps, 
not only in lithological character, but also in the fact that here as there they 
contain a number of older forms of life side by side with new arrivals. Such is, 
it appears, the case with the Werfen beds of Armenia'. 
The following forms of the 1st and 2nd groups of the lower Trias are identical 
with such of the Werfen beds of the Alps:— 
Momtis claree, Emm. 
„ anffusta, Han. 
Oervillia mytiloides, Sclil. 
Modiula triquelra, Seeb. 
MyophoHa ovata, Gclf. 
Avicula ‘venetUma, Hau. 
Nearly identical with a Hallstadt foim is Ophicems (Amm.) densitesta, Waag.^ 
All the other species represent earlier stages of forms found also in the 
triassic beds of the Eastern Alps. 
So for instance :— 
r Hiingarites (?) Stfombecki, Griep. 
Otooeras tooodwardi allied to } „ scapliitiformis, Hau. 
I „ zalaensis, Bokh. 
Opliiceras tibeticum, n.s., allied to Lgtoceras simonyi, Hau., and other Lytocera- 
tites, occurring in the Lower Trias. 
DESCRIPTION OF NEW SPECIES. 
Class: CEPHALOPODA. 
Order : TflTRABEANCHIATA. 
Family: NAUTILI BAH 
Genus : NAUTILUS. 
Nautilus quadeangulus, Boyr., var. beahmaxicus, n. s. Plate I, figs. 1—3. 
This species is most nearly allied to the Liassic forms, of which N. aratus, 
Schl., is the representative. The shell is considei’ably involute, the umbilicus deep. 
The ventral side flattened, the section of the shell sub-angular. The descent to 
the umbilicus is vertical and sharply defined. Five radial linos of gi’owth are 
visible, and a few broad indentations at intervals of about f inch along the last 
chamber indicate a faint kinship of this form to Nautilus fiigax, Mojs.^ Towards 
the mouth the shell opens out, trumpet-shaped. What remains of the last
