As noted already, forms presenting a type of organization closely re¬ 
sembling that of Hartmann’s “female form” are also found in Coptolermes 
formosanus, in company with the forms representing the type of his “male 
form,” or Pseudotrichonympha. 
Three species of Holomasligotoides are distinguished by Grassi (1917)— 
H. hertwigi Hartmann, H. mirabile Grassi (harboured by Coptolermes sjostedli 
of French Guinea), and H. hemigymnum Grassi (harboured by Coptolermes 
lacteus of Australia). The chief differences between them seem to be in the 
arrangement of the spiral bands of flagella. According to Grassi (1917), 
H. hertwigi has very numerous bands, H. mirabile has only 12, while H. hemi¬ 
gymnum often has no bands over a large part of the posterior region of the 
body. Grassi’s estimate of the number of bands in H. hertwigi is based upon 
Hartmann’s Figure 44, which shows 20; but Hartmann’s description and 
figures are not sufficiently accurate to warrant any definite conclusion re¬ 
garding their number. Another of his figures (Fig. 46) is said by Hartmann 
himself to show 14 bands, but the drawing is not at all clear. The species of 
Holomastigotoides found in Coptolermes formosanus is similar in size to that 
described from the Coptolermes of Brazil by Hartmann; but owing to the 
incomplete and inadequate description which he has published, it is impossible 
for me to determine with certainty whether his species and mine are the same 
or different. From Grassi’s brief descriptions it seems certain that his two 
species differ from mine, and I propose therefore to name my species Ii. harl- 
manni , provisionally regarding it as new. 
Holomastigotoides hartmanni sp. nov. (PI. XIII, figs. 43-52). 
This is a large and plump form, commonly oval or elliptical in outline, 
and slightly narrowed at the anterior end. It usually measures 50-140 g in 
length, but sometimes as much as 170 g; its breadth being usually 30-80 p, 
exceptionally attaining 100 p. On the greater portion of the body a distinct 
and well-developed periplast is recognizable. The shape of the body is not 
changeable. (See PI. XIII, fig. 43.) 
Close spiral bands of deeply stainable minute granules, as seen in Pseudo¬ 
trichonympha and Microspironympha , are found over the greater portion of 
the body, excepting a small area at the posterior end, equal to about one- 
ninth of the whole body. The bands contain the basal granules of the flagella, 
as in the other genera. The number of bands appearing on one side of the 
body varies from 30 to 50, according to the size of the organism. In the 
Brazilian species they seem less numerous and distributed more diffusely 
than in our forms, and in Holomastigotoides hemigymnum described by Grassi 
(1917) a large portion of the body remains free from bands, as mentioned 
above. The course of all of the bands may be traced to the anterior tip of 
the body, as in Microspironympha’, but the number of them originating at 
this point seems to be inconstant in the present species, and varies from
