V'crv fine examples ;it Stations 1 and 2. but extremely rare. In the deejicr water 

 the specimens beeome depauperate, but retain their cliaracteristic structure.

Stations 2, 3. 



At Station 2 a good many examples of this strongly limbate variety. At 

 Station 3 a few which are almost certainly fossils. The only previous record 

 is from the E. coast of Australia (465 fms.).

Stations 3. 21. 



A doubtful .specimen at Station 3, and a small but unquestionable specimen 

 from Station 21, in 1,714 fms., probably the deepest record hitherto.

Universally distributed, reaching its maximum development in the extreme 

 S., where it attaches itself to every solid organic and inorganic object. The 

 Polyzoa notable at Station 50 are covered with sessile individuals. These sessile 

 specimens are, as a rule, surrounded by a thin layer of mud, from which extend 

 tubes at irregular intervals all round the shell, the object evidently being to 

 convey the protoplasm, under protection, to some distance from the shell. Such 

 tube-bearing specimens are also found in quantity at Station 27. Here, as at 

 many otlier Stations, where the type is abundant, many of the .specimens are 

 .seen to be riddled with small circular holes, especially as to the terminal 

 chanrbers. Whether these are the borings of a parasite, or in the nature of
