A'OTES ON SPOROZOA — II.

mural is ol Portugal, for example, wliicli is found in that 
lizard in Russia, and again in Sontheru Austria, and in France. 
I associate myself entirely with the i-emarks of Laveran and 
Pettit in their later note (15) with regard to this tnatter. 
In one of Ids memoirs (8), Franca describes the different 
forms of haemogregarine winch he found in L. mural is in 
Portugal. The author leaves out of account altogether the 
species K. (H .) lacertte. This he does for two reasons; 
firstly, in accord.ance with the view just referred to, because 
of the different geographical locality of the host in the case 
of the lizards which he examined ; and secondly on the ground 
that several different forms have been really included in the 
specific designation lacertae. From what I have shown 
above, it wdll be evident that, on the contrary, we can recoguise 
and clearly distinguish a well-defined species, to which the 
name lacerta3 belongs by right. 
Franca creates no fewer than four new species, all from 
this one host, namely, II. nobrei, bicapsulata, marceaiii 
and nana. These different parasites nsually occur associated 
together in various groupings; and it is the exception rather 
than the rule to find them separately. 'I’he first three are 
typical karyolysing forms, and hence may be termed 
Karyolysus. The last named, it should be pointed out, is, 
as its name implies, a very small form. From the oidy figure 
given it is obvious that this is merely a young phase ; it cannot 
itself be regarded as an adult parasite, and in its older 
])hases it may possibly be identical with one of the other 
types described. At any rate, it seems distinctly premature, 
iti the circumstances, to give this type a new specific name. 
As regards Franya’s other three species, I confess straightway 
that I consider they are only different forms or phases of our 
old friend K.lacerta3. Iii have come to this conclusion 
j)rincipally on two grounds; in the first place as a result of 
the detailed comparison I have myself made of certain forms 
of K. lacertae, and of the alterations ])roduced in the infected 
host-cells as seen in smears stained with Giemsa and also in 
wet preparations stained with iron-haematoxylin; and secondly.
