Echiniscus dicboisii Eichters {15). Plate YI, fig. 3. 



Variety. — Small, red. Lateral processes : a, seta ; c, short 

 spine with enlarged base ; d, short spine with enlarged base and a 

 spicule near the middle ; e, a strong curved spine. Dorsal pro- 

 cesses : over c a small spicule, over d a strong serrate spine. End- 

 plate facetted. No barbs on any claws. 



Although this variety appears to differ considerably from 

 Eichters' type, I see no good reason to make a distinct species of 

 it, as I have found a series of forms resembling E. duboisii in having 

 some of the spines serrate, yet differing from one another in the 

 number of serrate spines. Some have both lateral and dorsal 

 spines serrate, others only the lateral, and others, again, only the 

 dorsal.

Echiniscus sp. 



Mr. Milne has sent me a sketch of an Echiniscus which has 

 four stout, straight dorsal spines on the posterior half of the body, 

 and no lateral processes except a. No such species has been de- 

 scribed, but as Mr. Milne, not having made a special study of this 

 group, fails to indicate on which plates the spines are situated, it 

 cannot be described till the animal is again seen. I failed to find 

 it in the moss sent to me.

Variety. — As this was first found in moss sent by Mr, Pearce, 

 a description will be found in the first part of this paper. . 

 Habitat. — Woodbush (coll. Mr. Jenkyns). 



Macrobiotus richtersii Murray {12). 



Though only described in 1911, in a paper on Irish Tardigrada, 

 the species had been long known. Professor Eichters figured the 

 egg in one of his papers, but without knowing the animal which 

 produced it. The esg was also known to occur in Uganda and 

 the Transvaal, but the complete study of the adult and ^he egg 

 was not possible till the species turned up in Ireland. 



The egg found in Africa belongs to the type, having large 

 truncate conical processes, each surmounted by a disk, which is 

 bordered with papillae. 



Habitat. — Pretoria (coll. J. Hewitt).
