Undtdina, g. n., E. Ray Lankester (Q. J. Micr. Sci. xi. pp. 387-389), will 
form the type of a new group, devoid of mouth (as in Opalind) and cilia, but 
provided with a broad crust-like undulating membrane. Type U. ranarum^

Cei'citium cumaonense, sp. n.. Carter {—C. fusca^ Ehrenb., var. P), Ann. N.

of 4000 to 6600 feet, sometimes in such numbers as to change the colour of 
the water to a rusty brown. They mostly occur, near the surface, seldom at 
a greater depth than 20 feet, and are perfectly visible to the naked eye. (Not 
fully characterized, for want of recent specimens.)
