Davis — On the Fossil Fish of the Cretaceous Formations of Scandinavia. 427 



present some features of great similarity to the species now described. Tlie body 

 is elevated and compressed ; the scapular arch large and well developed ; ribs 

 small and insignificant, and the inter-spinous bones large and expanded. The 

 vertebral column is more massive and stronger in proportion to the size of the fish ; 

 it is composed of twenty-four vertebras, whilst in the species now described there 

 are thirty. Gastronemus occupies a position intermediate between the forms 

 represented by Vomer* and the species now described, with a strong inclination 

 towards Vomer. Both these genera have the same number and distribution of 

 the vertebrae ; but in this species the vertebral column is smaller and less 

 robust, whilst the number of its constituents is larger. The pectoral fin is large 

 in Vomer and Gastronemus, but in this genus is comparatively small. The 

 greatest and most characteristic divergence will be found, however, in the 

 character and composition of the elements of the scapular arch.

Genus. Clupea. Linn. 



Body compressed, with the abdomen serrated, the serrature extending forwards 

 to the thorax. Scales of moderate or large, rarely of small, size ; upper jaw not

 present, rudimentary and deciduous. Anal fin of moderate extent, with less than
