they are surface animals, and are only very exceptionally found in 
depths under 400 m. 
Boroert has also a supplementary report on the distribution of the 
Doliolidce of the Plankton Expedition, in which he disagrees with Trau- 
stedt as to the identification of some of the species, and discusses fully 
the synonymy of the species and their horizontal, vertical, and seasonal 
distribution. 
IV.— SYSTEMATIC. 
Apstein (1) reports that the Salpce in the Berlin Museum represent 12 
species and 2 varieties, none of which are new. He considers, from 
his examination of a large number (about 850) of specimens, that 
S. bicaudata, Q. & G., ought to come under S. scutigera-confcedcrala . , 
and that S. quadrata, Herdm., is probably its solitary form, that 
Herdman’s S. runcinata-fusiformis var. echinata is S. aspera , Cham., 
that the solitary form of S. afric arid-maxima is Meyen’s S. aniarctica , 
and that possibly S. coerulea, Q. & G., is S. cylindrical Cuv. 
Seeliger (2) in his history of the Tunicata, give3 the various more 
important classifications which have been proposed, and discusses the 
more reoent, such as those of Herdmau and Lahille. 
Boroert gives a systematic account of the Doliolida!.
