are distinctly paired. On the median line below the intestine the ends of each 
glandular mass meet and join into one duct, the one I have just referred to. The free 
ends of the glandular masses are attached by mesenteric tissue to the ventral or sub- 
intestinal blood trunk. 
A much smaller tubular gland of the same nature runs between the dorsal 
vessel and the intestine; discharge duct unobserved. A yet smaller gland is seen 
above the subventral vessel in the same somite as the former; its discharge duct could 
not be followed. 
These glands stain exactly as the common supra-pharyngeal glands and septal 
glands, but they show no similarity as regards reagents with the chloragogice cells of 
the intestine and blood vessels, in corresponding places in the somites posterior to x1. 
The septal glands appear to be of about equal size, a close-examination being im- 
possible, from want of sufficient material. 
Other glands are found in the epithelial walls of the intestine, arranged in 
clusters, like the cloves ina garlic. They are scattered about at short intervals among 
the epithelial cells, and appear of the same nature as those I have described in Ar- 
gilophilus, but they are not as numerous as in that species. They do not stain freely, 
but stand out bright and pellucid among the darker staining cells. 
Typhilosole not present. 
Gizzards are connected by a very thin wall of the same nature as the cesophagus. 
As far as I can make out the gizzard must be in v and vi, at least the posterior gizzard 
is bound by the septum separating viand vil. The circular muscular layer is about 
30 strands wide, and is at the widest place about four times thicker than the epithelial 
layer and cuticle together. The whole width of the gizzard wall is little more than 
twice that of the body-wall in that somite. The longitudinal muscular layer of the 
gizzard is only one single strand thick, and the thickness of this strand is less than 
any one strand of the circular layer of the gizzard. The epithelial layer is com- 
paratively thick, about one-fifth of the whole gizzard. It contains the same peculiar 
glands as I figured in Benhamia. 
Spermathece. The absence of diverticula is interesting in as much as most 
species of related genera possess them. There are, however, some warty elevations. 
The muscular or basal duet is very long, slender and tubular, several times longer 
than the upper ovoid sae (fig. 74). The muscular part offers no peculiarities of 
structure. The spermathecze occupy each only one somite. They stand upright fol- 
lowing close to the anterior surface of the septum. 
Testes are greatly lobed and are situated high up on the septum, just as are the 
ovaries. : 
Spermducts and ciliated rosettes. The spermducts are separated, but enclosed 
in a common muscular sheath until somite xxi is reached. Between xx and xvi the 
two ducts fuse into one lumen, which opens out into the center of somite xxi. The 
double lumen runs along the circular muscular layer forward until somite xiii/xu, 
when the respective ducts rise upwards following the septum to the ovary and testes. 
From here on forward each duct is thicker and muscular, and instead of following the
