TWENHOFEL: EXPEDITION TO THE BALTIC PROVINCES. 
about the same horizon of the marl beds at St. Johannis. At that 
place the rock is said to be quite dolomitic. The exposure is no 
longer in existence. Fossils which have been collected there are: — 
Eospirifer radiatus. 
Leptaena rhomboidalis. 
Meristina tumida (Dalman). 
Platystrophia biforata lynx. 
Spirifer crispus Dalman. 
Orthoceras canaliculatum: 
Calymene tuberculata Brunn. 
Encrinurus punctatus. 
Oncholichas ef. gothlandicus Angelin. 
ornatus Angelin. 
Proetus concinnus osiliensis Schmidt. .

At Leal, on the western end of the mainland, the once extensive 
quarries are now to a considerable extent overgrown. The rock is a 
fine-grained dolomite which becomes yellowish white on exposure. 
Originally there may have been twenty feet exposed, but at present 
not more than one third of this is shown. Few fossils appear to be 
present. 
At Kuiwast on the eastern side of the Island of Moon, a brownish 
gray to yellowish white, fine-grained crystalline dolomite outcrops on 
the beach. At most levels it has a gnarled structure and appears to 
be largely composed of coralline material, although the fossils have 
been completely destroyed. In a few places the bedding is regular. 
A similar rock, but with bedding in some places well defined, out- 
crops at many localities on Moon. At the base of Igo Pank and 
Pussininna Pank occur soft, bluish gray and yellow, not well or finely 
crystallized dolomites with well-defined bedding. The overlying 
rocks are cavernous dolomites which, being more resistant to wave- 
erosion than the softer underlying strata, overhang the latter in many 
places, producing a wild and picturesque coast. Fossils are quite 
rare in the rocks at the top of the cliffs, but in the softer beds beneath 
they are more common. The former beds are probably the same as 
those of Kuiwast, and they appear to compose most of the surface 
strata of the northern interior of Moon. 
Fossils from the basal beds of the two Panks mentioned are: — 
1. Hindia fibrosa Roemer. 
2. Halysites catenularia.
