II. — BIOLOGY. 
a. Anatomy. 
Ritter, in his description of Perophora annectem , reaffirms with 
further evidence what he had already stated — that this Californian form 
shows within the limits of variability of a single species a complete 
transition from the Simple and “ Social ” to the Compound Ascidians. 
Garstang proposes a modification of Lahille’s classification based upon 
anatomical and embryological facts. 
Metcalf has a variety of anatomical notes, chiefly on minute glands 
in the pharynx and cloaca of Cynthia partita , and on points in the nervous 
system and sense-organs of Salpa and various other Tunicates. He also 
gives re isons for regarding the ciliated funnel in Boltenia , &c., as a sense- 
organ. 
Caulcery deals with the reconstitution of the colony in Diazona. 
Ritter describes and discusses fully in all its relations a new species 
of Goodsiria (G. dura) found on the Californian coast. He considers in 
some detail its systematic position, and its relations to other members of 
the family Poly sty elida;. A short account of the anatomy is also given, 
and of the relations of the zooids in the colony in their connection with 
budding (see under Development).
