MKRRfAM: TKTASSIl' ICHTHTOSAUKEA.. 



the Wellenkalk of the lower Muschelkalk, Fraas has mentioned Rhordorf, 

 Cuhv, Aaeh, and Niederschach. The vertebrae at Zurich came from the Well- 

 endolomit of Laufenberg in Canton Aargau and from Ohereggingen. Mate- 

 rial from the Wellenkalk of Qnerfurt north of the Ilarz is in the museum at 

 Halloa. S. 



From the middle of Muschelkalk of Freyburg a. U. ichthyosaur-like verte- 

 brae have been obtained. 



The upper Muschelkalk of Bayreuth has furnished several valuable speci- 

 mens, including vertebrae and elements from both pectoral and pelvic arches.

Descriptions of some of these specimens will probably appear in the near fut- 

 ure. Also from the upper Muschelkalk are several vertebrae of ichthyosaur- 

 ians from Grossreifling in Steiermark. From this locality there was also 

 obtained in 1843 a very large skull with numerous vertebrae and other ele- 

 ments of the skeleton. This specimen was destroyed by fire in the museum of 

 Admont in 1863. No careful study of it was made by a specialist in vertebrate 

 palaeontology. At the present time there is some uncertainty as to its true char- 

 acter. H. von Myer (1847, pp. 190 and 191) described it from a sketch, and 

 from information furnished by others, and compared it with Ichthyosaurus 

 ]>l<itijodon. A copy of an old sketch reproduced by von Arthaber (1896, p. 14) 

 does not show any characters which indicate other than iehthyosaurian affini- 

 ties. Other upper Muschelkalk remains, now- in the mineralogical museum of 

 Jena, are known from beds near Weimar.
