gradually retracted from the test, became more spherical in form, and the 

 nucleus became more visible (Pi. 9. fig. 11). This may liave been preparatqry 

 to encystment. 



The size of the animal varies slightly. Large specimens (adults) generally 

 were about 34 /* long, 27 /n wide, and 18 fi thick, but smaller individuals were 

 common. 



It is interesting to notice that this species was discovered and examined 

 before the author received a copy of Penard's paper describing the only other 

 known species of the genus. 



EuGLYPHA BRYOPHILA, sp. nov. (Plate 9. figs. 14-15.) 



At different times, amongst the drier mosses of woods, from districts as 

 widely separated as Monsall Dale (Derbyshire), Port Patrick (Wigtownshire), 

 Glen App (Ayrshire), and Kincardine O'Neil (Aberdeenshire), I have met 

 with examples of a Eugli/plia which seems to me sufticiently characteristic to 

 merit specific rank. 



The test is very regular in form and subject to no marked variation. It is 

 compressed and in broad view elongated oval, with rounded dome, and lateral 

 margins gradually narrowing with even curvature to the borders of the 

 mouth. In narrow view the dome is somewhat pointed and the lateral 

 margins run in almost straight lines to the mouth. The outline is very even, 

 and may compare with that of JE. hvvis, Perty. 



The mouth is almost circular and bordered by six plates, each having one 

 blunt rounded central tooth, with a minute lateral tooth on each side, often 

 very difficult to distinguish (PI. 9. fig. 14 a). The plates of the test are 

 distinctly marked, are elliptical in shape, and arranged as in i'. alveolata, 

 but with some slioht irreoularitv towards the mouth. 



The crown of the test carries a cluster of four or five long, sharp, curved 

 spines, of a nature similar to those found in J^. cristata, Leidy. 



The protoplasm is quite normal. 



Size : length 50 /a ; breadth 23-25 /j, ; thickness 16-17 /ju ; mouth 9 fi ; spines 

 about 16 fjb or more. 



I was at first inclined to regard this as a variety of E. cristata, Leidy, 

 owing to the presence of the cluster of spines, but this is the only respect in 

 which the two forms are similar. U. cristata is quite peculiar amongst 

 EiKjlyplue in being very slenderly built and having a distinctly tube-like 

 uncompressed form, with a very characteristic arrangement and appearance 

 of the plates of the test. In none of these characters does the present 

 species resemble it. Further, it is very unlikely that a variety of a species 

 normal to sphagnum, which occurs in dry moss, would be of more robust 

 build. 



Dr. Penard, in 'Mem. Soc. phys. et hist. nat. Geneve,' 1890, pi. 9. 

 figs. 91 & 92, figures two individuals as broad forms of E. cristata which
