small intestine are provided with distinct round nuclei (fig. 2). The 
foremost part of the ventricle, especially its two coeca, is provided 
with a comparatively great number of brightly coloured glandular 
cells: (fig. 2 2), each of which is more. or less elongated, provided 
with a large nucleus at its base and has the distal part filled with 
granules of secrete. On the inner side of the colon there is, as 
usual, a single layer of higher or lower epithelial cells with indistinct 
nuclei; besides these there is a great number of glandular cells, most 
like those of the anterior coeca, but shorter; when they are filled 
with globules of secrete (fig. 12 & 13 2), their ends are often much 
broader than their base. The walls- of the short rectum consist of 
a low epithelium with distinet nuclei (pl. VI fig. 2). 
The intestine is enveloped in aåa muscular sac (pl. V fig. 12) 
the muscular bands of which are crossing each other in all. direc- 
tions but mostly under almost right angles. The spaces between 
the bands thus become more or less square or rectangular and are 
usually much larger than the bands but sometimes will become very 
narrow as the bands are placed nearer to each other. Between the 
bands are small elongated nuclei and a thin layer of fibrous tissue 
which: may naturally be regarded as the tunica propria of the 
intestine. A corresponding muscular saåc seems to surround the 
accessory glands of the male. A similar system of muscles is found 
in the Oribatidae (Michael 10 pag. 150. Pl. E fig. 10), where 
the arrangement is more regular and the transverse striae of the 
bands easily seen. 
The ventricle often contains Gregarines (?) as internal parasites. 
These are often provided with a single nucleus and are sometimes 
placed with the head into a cell. There seems to be two kinds, 
the one is 0,067" long and provided with a large round head 
(0,008mm) the other kind is 0,247, merges into.a thinner tail and 
is terminated with a head as broad as it is long and connected 
With the body by a thinner neck. The cavity of the ventricle is 
filled with round bodies (0,02—0,067—) consisting of a thick wall 
and an inner protoplasmatic mass. The wall is of a rayed structure
