XXVII.— " Scotia " Collections— Further Note on Microscopic Life 

 on Gough Island, South Atlantic Ocean — Rhizopoda. By 

 Dr Eugene Penard, Geneva. (Communicated by William Evans, 

 F.E.S.E.). 



(Read 18th December 1911. Received 24th Jauuary 1912.) 



[Explanatory Note by W. Evans. In the summer of 1907, shortly before 

 his departure for the Antarctic, Mr James Murray examined, for micro- 

 organisms, a small tuft of moss brought from Gough Island, in the South 

 Atlantic Ocean, by the Scottish National Antarctic Expedition of 1902-4. 

 Not having time to examine the material exhaustively, Mr Murray passed 

 on the residue (contained in one small bottle) to Dr E. Penard for more 

 thorough examination. Mr Murray's report was communicated to this 

 Society in November 1907, and published in the Proceedings early in the 

 following year (vol. xvii. p. 127). In April 1908, Dr Penard sent to 

 Dr Bruce the following account of the species he had found in the 

 material received from Mr Murray.] 



List of Ehizopoda, etc., found in Moss-residue from Gough Island. 



The following is a list of the Ehizopods I found in the material received 

 from Mr Murray : — 



Arcella discoides, Ehrbg. — One specimen, very small. 

 Parrnulina brucei, spec, nova (see p. 245). — About ten specimens. 

 Difflugia constricta, Ehrbg. — One specimen. 

 Euglypha ciliata, Ehrbg. — Pare. 

 „ compressa, Carter. — Rare. 



„ laevis, Perty. — I refer to this species, though doubtfully, 



moderately numerous, very small and very broad 

 specimens with fine and distinct alveoli. 

 „ strigosa, Leidy. — Rare. 



Heleopera pctricola, Leidy. — Large, clear, very light pink colour ; 

 very likely this is the species found by Murray, but it 

 differs from var. amethystea, Penard, which is still larger. 

 Nehela caudata, Leidy. — One specimen only. 



„ collaris, Leidy. — Rather abundant; 1 in several forms (as a rule 

 small). 



' When I say " abundant," it is only " relatively " to other species, for in fact the specimens 

 were few compared with the average " richesse " of mosses or Sphagnum.
