distribution of Auwcella has been dealt with by Pompeckj,*

tian times in a ep direction. The occurrence of 
Aucella in the beds of Hazara is in exact conformity with 
this hypothesis, as also with the direction of migration indi- 
cated by him. According to Pompeckj this migration must 
have taken place during Kimmeridgian and Tithonian times, 
a theory very much corroborated by the striae tia in the 
overlying beds, of the well-known Tithonian fossil Perisphinctes 
(Virgatosphinctes) siriaay

includes several casts of Cardium, sp-

The specimens were all obtained from the Gieumal sand- 
stone overlying the Spiti shales and developed near Kuthwal 
and they include the following :—

of Arca— 4. Boertond ana—has been recorded from the Spiti
