and perhaps other towns. Fossils are quite common, but generally 

 not well preserved. Those most common are Acervularia luxurians, 

 Clathrodictyon, large stems of Crotallocrinus, Whitfieldella prunum, 

 Ctcnocjnathus murchisoni Pander, and Gomphodus sandelensis Pander. 

 The horizon is practically identical with that of Moritz. 



The Lode locality is about two miles west of Arensberg, and the 

 present exposures are in an old well of which the top is not more than 

 ten feet above sea-level. About six feet of interstratified gray and 

 blue limestones and shales are exposed, which appear to belong to 

 nearly the same horizon as that of Kasti or Moritz. The fossils were 

 collected on the dumps, those most common being Crotallocrinus 

 rugosus Miller, MonticuUpora fletcheri, Rhipidomella hybrida, Homeo- 

 spira scdteri, Spirifer elevatus, Whitfieldella prunum, Calymene specta- 

 bilis, and Proetus conspersus Angelin. 



About the most fossiliferous locality of the Kasti zone is that of 

 Kaugatoma Pank on the Sworbe, where strata are exposed which 

 excellently typify the lithology of the upper division of the Oesel 

 formation. The height of the cliff at Kaugatoma Pank hardly ex- 

 ceeds twelve feet, but the exposures are increased by several feet 

 which are shown on the beach. At the water's edge are three to four 

 feet of thin limestones and calcareous shales, the latter being filled 

 with extremely fine fossils. The upper portion of the beach is covered 

 and about four feet of strata are concealed. The lower five feet of the 

 cliff consist of thin limestones and shales like those below, and contain 

 essentially the same fossils. At the top of the cliff are six or seven 

 feet of heavy-bedded limestone which is quite similar to that of Nes- 

 soma and elsewhere on the southern coast. The species whose names 

 follow have been collected.
