Micr. Science, vol. xiv. (1868) p. 72. 
Lankester, E. Ray. On a new Parasitic Rotifer, and on the 
Synaptce of Guernsey and Herm. Quart. Journ. Micr. 
Science, vol. xvi. 1868, p. 53, woodcut. 
Records the occurrence of a Rotifer, apparently undescribed, 
found parasitic in the body-cavity of Bynapta sarniensis and S. 
inh(Rrens. Associated with it was a very active Trichodina.

Aquariums fur Ereunde des Mikroskopes und der Natur- 
wissenschaften. II. Buch. Die Raderthiere. 8vo, Leipzig, 
1868, pp. 1-34, with 8 plates. 
This interesting little work, though meant to be more of a 
popular than a scientific treatise, gives a very fair account of 
the general structure of the Rotifera, and, following Dujardin^s 
classification of the Rotifers into R. sessilia, R. natantia, and R. 
repentia, proceeds to give details of some of the families of each 
suborder, as well as of the more remarkable genera and species. 
There are sixty figures, on eight plates; and though roughly 
drawn, the species are almost always recognizable.

ClaparMe’s remarks as to the mode in which certain Rotatoria introduce 
food into their mouths are translated in Ann. & Mag. Nat. Hist. vol. i. 18G8, 
p. 309 ; also on Balatro cairns^ ibid. p. 385 {vide ‘ Record,’ 18G7, p. 623).
