Object remarks: Each specimen in individual glass tubes with labels. Probably identical with: 'The *Raja* embryos were obtained from the zoological station at Kristineberg on the west coast of Sweden, were the eggs, laid by caught females, were allowed to develop in large tanks' (Bäckström, 1924 p.7).
Locality remarks: Maybe this material was only dissected by Bäckström in 1922 and collected (by somebody else?) earlier.
