72 BRITISH FRESHWATER RHIZOPODA. 



Test cbitinous, liyaline, marked similarly to that of 

 L. spiralis (the "rods," however, being usually reni- 

 form, and stouter), slightly or not at all compressed; 

 its contoiir, viewed laterally, round or broadly ovoid, 

 the neck appearing in side view as if poised at a 

 tangent, turgid, narrowed at the mouth. 



Dimensions: Length 110-125 /a; breadth 75-80 /a. 



In wet SfJiagnum, Dunham, Cheshire, 1905; much 

 less common in Britain than the two preceding species. 



This species is distinguished from L. spiralis by its 

 smaller, more globose body, and the peculiar position.

in relation to it, of the neck (fig. 76). Like L. spiralis 

 the animal is very active in its movements, and the 

 pseudopodia have a habit of enveloping the test; 

 sometimes a long stream of ectoplasm will issue from 

 the mouth of the test, and send out from this short 

 subsidiary pseudopodia on both sides. We have only 

 met with the species in the locality above named.

Larger than average examples of L. sjiiralis, simi- 

 larly constructed but less elegant, differing mainly in 

 the outline of the test, which is relatively much 

 broader, and in side view is divided roughly by a 

 shallow depression on the dorsal surface into two 

 turgid unequal portions. The measurement across
