Rhisopoda of England and India. 291 



Animal. The same as that just described, and as in Euglypha 

 generally. Pseudopodia and contracting vesicles not seen, but 

 may also be inferred to be the same as in Euglypha. 



Hab. Heath-bog water. 



Size. Body xfrth of an inch in diameter; neck -,- J th 

 broad. 



Loc. Budleigh-Salterton, South Devon. 



Obs. This species is very plentiful in its habitat, but very 

 small. Its features are very constant, and its size also ; but I 

 have never been able to see its pseudopodia, although I have 

 watched it long and repeatedly. The presence of supernumerary 

 scales in it is exactly like that which I have already figured in 

 Euglypha alveolata and in E. pleurosloma (Dujardin's Trinema). 

 Its relative size, as well as that of E. spinosa, in proportion to 

 the other testaceous Ilhizopoda which I have figured (/. c), will 

 be observed in dotted outlines (tigs. 13^ and 14 c?). 



EXPLANATION OF PLATE XII. 



N.B. — Figures 1 to 10, inclusive, are drawn upon the scale of ^th to 

 54 ' 0c) th of an inch, and fig. 11 upon a little larger scale. Figure 12 is 

 upon the scale of -rVth to j^th of an inch, and fig. 13 upon that of ^th 

 to TnAro-th of an inch, while fig. 14 is upon the scale of ^ tli to ^jV^th of an 

 inch. Figures 13rfand \4g are outlines of figs. 13 and 14 respectively, 

 on the scale of ^th to ^-^th of an inch, for comparison with those of the 

 testaceous Rhizopoda in plate 1, vol. xiii. of the 'Annals,' which are on 

 the same scale; and fig. 12 h, i would be the lengths respectively of fig. 12, 

 if drawn on the scales first and last mentioned in this paragraph. 



The Actinophryina and Acinetina should be viewed not as discoidal, but 

 globular bodies, with tentacles proceeding from their surfaces generally, 

 and therefore the marginal lines of vacuoles only as an indication of the 

 peripheral or ectosarcal layer which exists all over them respectively. 



Fig. 1. Actinophrys oculata, Stein. Group of four individuals, the largest 

 T^th of an inch in diameter, each presenting a nucleus and 

 nucleolus, and all bearing drops of sarcode on their tentacles, 

 but the latter only represented in a 5 b, uniting sarcode ; c, va- 

 cuoles in the latter, containing food ; d, vacuoles containing each 

 a subrotund, colourless, amylaceous (?) body. 



Fig. 2. The same : outline only of a group of nine individuals, in every 

 respect the same as those of fig. 8, but with smooth tentacles : 

 a, circles representing the Actinophryans, sVnth of an inch in dia- 

 meter ; b, uniting sarcode ; c c, vacuoles in the latter, containing 

 respectively the remains of a rotatory animalcule ; d, as before. 



Fig. 3. The same (?), in the form of Actinophrys Sol (?) ; nine individuals 

 in the group, closely approximated, and varying in size, the 

 largest (a) being ^-^th of an inch in diameter ; b, two or three in 

 zygosis ; uniting sarcode not seen ; c, vacuoles in the latter, con- 

 taining food ; d, as before. All the above from salt water, in 

 India. 



Fig. 4. Actinophrys Sol(l); three separate individuals, each ^-fa-th of an 

 inch in diameter, each bearing tentacles, each presenting an 

 ectosarcal layer of vacuoles, but no nucleus : a, specimen with
