TUN I CAT A. 
Traustedt (27) enumerates upwards of 70 species of Simple 
Ascidians which have been found in the Pacific Ocean; 7 of these 
he describes as new. 
Wagner (29) records 10 species of Simple and 1 of Compound 
Ascidians from the White Sea, including 2 new species of Molgula and 
1 of Cynthia. 
Herdman (9 and 13) records the Tunicata found in the N. Atlantic 
during the ‘Lightning,’ ‘Porcupine,’ and ‘Triton’ expeditions. 
Traustedt (26) discusses the geographical distribution of the Balpidcc 
throughout the great ocean basins.

ASCIDLE SIMPLICES. 
Clavelinid^e. 
Stutter (25) supports Herdman’s view that this family should be 
regarded as belonging to the A scidice Simplices. He has found at Billiton, 
in the Malay Archipelago, two new species of the genus Ecteinascidia 
which show intermediate characters between the Clavelinidce previously 
known and such typical Simple Ascidians as the Ascidiid.CE. 
The process of gemmation and life-history of Clavelina are discussed by 
Seeliger (23). 
E. van Beneden & C. Jultn (3) give an account of the development 
of Clavelina. [See Development.]

Roule (21) discusses the characters of this family, and its division into 
subfamilies and genera. He adopts Herdman’s classification into 
Boltenince, Cynthince , and Styelince , and describes various species belong¬ 
ing to the two latter subfamilies.
