Microscopic Life on Gough Island. 245 



Phryganella hemisphaerica, Penard. — Eare. 

 Sphenoderia fissirostris, Penard. — Not very rare. 



Trinema enchelys (Ehrbg.). — Not rare ; always very small form, as 

 generally found in mosses. 

 „ lineare, Penard. 



Such are the Khizopods I found in the Gough Island material. They 

 are few in species, and each species is poorly represented in numbers, yet 

 this note may be of some interest, and for several reasons : — 



1. All are species found in Europe (except one, Parmulina brucei), 



and did not differ in appearance, except that they were 

 perhaps on the average a little smaller. 



2. They represent, most of them, the typical fauna of mosses, but 



the scarcity (one specimen only) of Difflugia constricta, a species 

 always so abundant in mosses, is remarkable. 



3. With the exception of the above, no Difnugias were observed. 



Murray found one "Difflugia spec," but it was very likely 

 Phryganella hemisphaerica. In Europe, and indeed every- 

 where, Difnugias (except constricta) are rare in mosses. 



4. One species has never been found before, namely Parmulina 



brucei, nov. ; but it will probably be found somewhere else 

 one day or other. 1 I append a description of this species, or 

 rather of its envelope, which was the only part of the 

 organism available. I have taken the liberty of naming it 

 brucei, after the leader of the " Scotia " expedition. 



For other organisms besides Ehizopods I did not look specially, but I 

 found the following : — A small rotifer (Brachionus ?), about twenty specimens 

 of Callidina angusticollis, Murray, a small diatom which was abundant 

 (Meridion sp.), and a good many samples of Merismopedia — very likely 

 that "blue-green tabular Alga, with the cells grouped in multiples of 

 four," which Murray mentions. 



Parmulina brucei, spec, nova; 



Enveloppe chitineuse, jaunatre, en forme de pyramide ou de cone 

 tronque, a base deux fois environ aussi large que le sommet. De ce 

 sommet, ou plateau dorsal, partent un certain nombre d'ar&tes (14 a 16 



1 I have this year-(1911) found this same species, though very likely a special variety of 

 it, in mosses collected by Dr Fuhnnann at an altitude of 3000 metres, on the Andes of 

 America (Colombia).
