SAURIAN FOSSILS. 



For the following information we are indebted to Prof. Bronn of 

 Heidelberg. 



A collection of two Mystriosauri and six or seven Ichthyosauri, 

 from the lias of Germany, will be sold, together or separately, at 

 Heidelberg, on the 1st of October 1844. All possess perfect heads 

 (the bones being separate in the Ichthyosauri), the body complete as 

 far as the tail, and at least a portion of the extremities more or less 

 perfect. The Mystriosauri are of the species M. Mandelslohi, n. sp., 

 with 48 vertebrae, 11 feet long ; and M. longipes, n. sp., with 53 ver- 

 tebrae, and 5 feet long. Five specimens of Ichthyosaurus acutirostris, 

 Ow., are respectively perfect as far as the 65th, 102nd, 117th, 122nd 

 and 123rd vertebrae, and one, I. communis (if it is not a new species), 

 perfect to the 66th vertebra. The Ichthyosauri (from 4 to 9 feet 

 long) have been described in the * Neue Jahrbuch fur Mineralogie,' 

 1844, p. 385-408, pi. 3 and 4; the Mystriosauri in the Supple- 

 ment to the ' Gavials Fossiles du Lias' by Bronn and Kaup, p. 37- 

 47, pi. 5 and 6.
