LITTLE-KNOWN BRITISH RHIZOPODS. 79 



relation whatever to parasitic fungi, and can in no way compare with those 

 shown in Penard's figure (' Faiine rhizopod/ p. 356) and which are described 

 as " short obtuse hyaline needles.'^ The protoplasm is like that of Nebelas 

 generally. Within the fundus it is crowded with yellowish food-bodies and 

 diatom frustules, while within the neck a comparatively narrow band of clear 

 protoplasm passes to the mouth, where it expands to the full width of the 

 neck, and generally gives rise to one or two pseudopodia. 



Size : length of test 100 fi; breadth 44 yu, ; width of neck 14 /^ ; length of 

 oils about 12 fi.

From the examination of individuals found in the English Lake District, 

 this form w'as previously described as a variety of N. ■militaris, Penard. 

 Since that time I have had opportunities of examining many specimens 

 from different localities, including Stanage (Derbyshire), Duddon Valley 

 (Lancashire), Scawfell and Helvellyn (Cumberland), Ben Ledi (Perthshire), 

 Glen Shee (Perthshire), Stranraer (Wigtownshire) *. The characters are 

 always quite distinctive and the animal shows little tendency to variation, 

 and no transitional forms connecting it with N. militaris are met with. I 

 therefore now regard it as an independent species. 



In (Jash's monograph, vol. ii. pi. 27. figs. 5 & 6 are named and described 

 as iV. harhata, Leidy» This is obviously an error, and the figures probably 

 are to be identified as referring to JV. tuhulata (see remarks under i\^. harhata, 

 svprc(, p. 78). 



Nebela scotica, sp. nov. (Plate 9. figs. 5-8.) 



This Rhizopod was found in large numbers in sphagnum gathered from the 

 middle slopes of Ben Ledi (Perthshire) in August 1910. The test is 

 compressed, and in shape broadly pyriform, with rounded dome, which 

 contracts abruptly into a short thick neck with lateral margins narrowing 

 slightly to the borders of the mouth. In narrow view the dome is rounded, 

 and the sides slope gradually to the mouth with only very slight concavity. 

 The mouth is broadly elliptical with an irregular margin and no lateral 

 notches. The surface of the test is somewhat variable, and sometimes 

 inclined to irregulariiy. It is covered with transparent, colourless scales, 

 occasionally almost rounded, at other times irregular in shape, of very 

 variable size, and sometimes distinctly overlapping, with smaller scales 

 overlying the corners where three or four scales meet (PI. 9. figs. 8 a & Sh).

 in the Ann. Scot. Nat. Hist. 1911, pp. '22G- 232.
