Seeliger (25), in the first number of his article Tunicata , for Bronn’s 
“ Klassen und Ordnungen des Thierreichs,” discusses the history of our 
knowledge of the group, commencing with Aristotle and the ancients, 
then working up through the Middle Ages and the Renaissance to the 
zoologists of the eighteenth century, and ending with the establishment 
of the group Tunicata , by Cuvier, Lamarck, and Savigny, in the early

Brooks discusses a number of phylogenetic points, and other matters 
of wide interest, in his chapter on Salpa , in its relations to the evolution
