VI. TUNICATA. 
c. Geographical Distribution. 
Seeliger commences his “Lieferung” 6 with an account of the distribu- 
tion of the Appendiculariidao (Larvacea) both vertically and horizontally 
in the Ocean. 
Herdman gives a preliminary list of Tunicata (and other animals) 
dredged in Puget Sound — including some new species — which will be more 
fully reported upon in next year’s record. He draws attention to the 
similarity between the Puget Sound fauna and that of North Europe. 
Bancroft discusses the Pacific species of Chelyoso7na. 
Herdman notes some of the species of Ascidians found at Port Erin in 
the Isle of Man. 
III. SYSTEMATIC. 
No new species have been described in 1897 ; and there havo been no 
papers dealing with classification, or establishing larger groups — with the 
exception of the preliminary notice of Ritter's new family of “Social” 
Ascidians in “Science” for March 12th. As however no generic, specific, 
or family names have yet been given to this new form, it cannot be 
formally recorded, and will no doubt figure in next year’s record.
