An examination of tliis list shows that the Chiavon fauna incUides no Ganoids, 

 and is constituted of Chondropterjgeans and Teleosteans. The hrst are represented 

 by two families, with two genera and three species. The second comprehend the 

 Arthropteri and the Anarthropteri ; the former with two families, four genera, and 

 fifteen species; the latter with eleven families, twenty-six genera, and forty species. 

 The whole are therefore comprehended in fifty-eight species, distributed in thirty- 

 two genera and fifteen families. 



Comparing the fish- fauna of Chiavon wiih twenty-one other analogous deposits of 

 Europe, I have come to the conclusion that they are in age Aquitanian, or belong, 

 like the strata of Sotzka, to the base of the Lower Miocene.

4. On an Iclithyosaurus from Mombasa, East Africa, ivith Observations on 

 the Vertebral Characters of the Genus. Bij Professor H. G. Seelet, 

 F.R.S. 



The author described two cervical vertebrae of an Ichthyosaurus from low- 

 lying country nine miles N. W. of Mombasa, brought to this country by Mr. New, 

 a missionary, and submitted to the author by Mr. Harris, F.G.S. The specimens 

 are from the cervical region, and differ in no way from such as occur in the 

 English Secondary clays. They are probably of Lower Secondary age. The 

 vertical height is 73 millimetres, the transverse width is 77 mm., and the antero- 

 posterior length is 34 mm. The author finds that the ratio of height to width 

 and of height to length, is a good means of distinguishing vertebrae in different 

 species, and that, when it is determined for each region of the body, it forms and 

 furnishes a valuable datum for defining a species on vertebral characters. The
