NOTES ON SPOUOZOA II, 
187 
Labbe placed forms wliicli lie regarded as similar to those 
described first by Danilewsky under the designation H . 
lacertee. Why, in so doing, he altered the specific name 
to lacertarum it is difficult to understand; the name should 
read, of course, K. lacertre (Danil.). From a study of 
Labbe’s description I do not think there is any reason to 
doubt that this author was dealing, in the main, with 
Danilewsky’s parasite, II. lacertae; though it is true that 
certain of his figures may represent some other Hremo- 
gregariue. Unfortunately, Labbe does not give any details 
about the particular species of lizard in which the various 
types of the parasite he figures respectively occurred. Since 
he examined four different species of host, in certain of 
which, at any rate, another llannogregarine is also para- 
sitic (as, indeed, he recognised, distiugnishiug this latter by 
the name '' Danile vskya lacazei, see footnote, p. 186), 
it is quite possible that he did not altogether succeed in 
separating the two forms. Nevertheless, leaving out of con- 
sideration his description of the “ endoglobular spornlation/’ ^ 
Labbe’s account of the appearance, size and structure of the 
young and adult parasites in the blood-corpuscles, and in 
particular his description of the marked alterations in the 
host-cell, make it perfectly evident that most of his observa- 
tions did actually refer to the same parasite as that described 
by Uanilewsky, and as that which I found in the lizards I 
examined. 
In 1901, IMarceau gave an account (18) of the Ilmmo- 
gregarine parasites which he observed in L . in ural is, and 
in this lizard alone; and here also it is quite obvious that the 
author was dealing chielly, if not entirely, with K. lacertre. 
On the whole, Marcean’s description agrees closely with that 
of Ijabbe. 
It is sufficiently clear, I think, that there is a definite 
' Tills process doubtless represents tlie schizogony of the parasite, 
whicli is apparently either of a double character, similar to that described 
by Reichenow (27) in the case of H. stepanovi, orelse of a type where 
se.vual dillerentiation is already manifest.
