cation in some details; the corona could not be studied at all and 
will have to be described from living specimens; on this subject 
Dr. de Beauchamp writes: 
“J’y joins des specimens de Notommata torulosa ou du 
moins de 1’espece que j’ai appellee ainsi jusqu’a ce jour. 
Peut-etre en effet n’a-t-elle pas droit a ce nom: j’ai ete 
etonne en examinant les individus vivants de trouver l’annu- 
lation moins nette et les oreillettes moins arrondies que je n’en 
avais garde le souvenir”. 
"Whether this species is really the one studied by Dujardin and 
subsequent authors it will probably forever be impossible to de¬ 
cide; it does not, however, do violence to the original descrip¬ 
tion to assume that it is, especially as it is found in France. In 
our opinion it ought to retain the name and to be considered the 
type of the genus Lindia, of which very little was known until 
de Beauchamp described and explained the action of this pe¬ 
culiar modification of the virgate mastax, which was then com¬ 
pletely unknown. We are gratified to be able to show that this 
modification is not a unique instance, but occurs in six other 
species of Notommatids.

The body is elongate, almost vermiform, and very slender, the 
greatest width being only one sixth of the total length. The 
integument is very flexible and fluted longitudinally and also has 
several transverse folds, so that it presents an annulate appear¬ 
ance, almost like a Bdelloid rotifer. It is a very transparent 
species. 
The head segment is short and narrow, about two thirds of the 
greatest width of the body; the neck is nearly twice as long, but 
very little wider; in addition to the two transverse folds separat¬ 
ing head and neck and neck and abdomen there is an additional 
faint transverse fold on the neck segment. The abdomen is very 
nearly parallel-sided and cylindric; it contracts rather abruptly 
to a conspicuous tail, with a single median lobe, rounded poste-
