characteristic feature of the fauna. The only other burrowing species 

 captured were Astropeden irregularis (one only), Corystcs cassivclaunus 

 (one only), Gonoplax angulata (one only, see p. 495). 



Fixed species. The hydroid fauna is practically identical with that 

 of Ground III., excepting that Halecium hedccinum is entirely absent, 

 and only a small quantity of H. Beanii was taken. There was only 

 a little Cellaria, and branched Polyzoa were scarce. 



Wandering species. The most characteristic feature is the abundance 

 of Palmipes p)lacenta. In other respects the wandering species are 

 similar to those found on Ground III., excepting that Solaster papposus 

 and Anapagurus laevis were plentiful, whilst Pandalus hrevirostris and 

 Buccinum undatum were not taken.
