[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 t(i 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 Rhizopods I found in the material received from 

 Mr Murray :— 



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

 Parmulina hriicei, spec, nova (see p. 245). — About ten specimens. 

 Difji.ugia constricta, Ehrbg. — One specimen. 

 Euglypha ciliata, Ehrbg. — Rare. 

 „ compressa, Carter. ^Rare. 



„ Isevis, Perty. — -I refer to this species, though doubtfully ; moderately 

 numerous, very small and very broad specimens with fine and distinct 

 alveoli. 

 ,, strigosa, Leidy. — Rare. 

 Heliopera petricola, Leidy. — Large, clear, very light pink colour; very likely 

 this is the species found by Murray, but it diti'ers from var. 

 amethystea, Penard, which is still larger. 

 Nehela caudata, Leidy. — One specimen only. 



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

 Phryganella hemisphierica, Penard. — Rare. 

 Sphenodena jtssirostris , Penard.— Not very rare. 



» 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.
