forward ; and those at the sides are longitudinal but 

 deeply undulated. Sometimes almost all the central 

 wrinkles are transverse. There are two longitudinal 

 rows of very short light-coloured hairs on the noto- 

 gaster. 



Distribution. — Mr. E. Bostock discovered this 

 species at Bull Bay, in Anglesea, and along the adjoin- 

 ing coast, in small pools of fresh water by the streams, 

 on alg£e {Prasiola stipitata), chiefly crawling on the 

 weed and on the rocks at the bottom ; it was in great 

 numbers, but it has not, to my knowledge, been found 

 elsewhere as yet. The name was selected by Mr. 

 Bostock. 



It is very interesting to observe the absence of 

 pseudo-stigmatic organs, which I have before remarked 

 in Orihata sphagni and the nymph of Eermannia his- 

 triataj both aquatic or amphibious creatures. In the 

 present instance I have failed to discover any trace of 

 pseudo-stigmata or pseudo-stigmatic organs either by 

 dissection or otherwise.
