A further contribution to our knowledge of the Rotifers, ac- 
companied by an excellent plate. The internal parasites of 
Hydatina, figured first by Leydig, are here described and figured 
from living specimens. 
Rhinops vitrea, gen. et spec, nov., Hudson, 1. c, p. 27, pi. 2. No generic 
diagnosis is given ; but this is an illoricated Rotifer. The ciliated wreath is 
divided into several series. The proboscis is ciliated all over its ventral sur- 
face and its edge, except at the extreme point ; this proboscis can be turned 
over towards the dorsal surface ; it also carries two brilliant-ruby eyes. It 
belongs to the Hydatinea, and was taken in some numbers in a pond at 
Bristol. 
Floscularia coronetta, sp. n., Cubitt, /. c. p. 135, pi. 24, on Fontinalis anti- 
pyretica, from small pools on Wimbledon Common. 
Floscularia prohoscidea, Ehrbg. (FI. campanulata, Dobie), is described and 
figured by Grenacher, 1. c. p. 483. 
Microcodon clavus, Ehrbg., is also described and figured by Grenacher, 1 . c. 
p, 487, Out of 100 examples examined, but one male was found. 
Triarthra longiseta, Ehrbg. Grenacher, 1. c. p. 491, describes and figures 
this species. The figure is excellent.
