the species. There are four pair of septal glands in vy, vi, vii and viii. The glands, 
as far as I can judge from dissections only, are of almost equal size, somewhat longer 
there than in Deltania Troyert. They are equally developed on the lower and upper 
side of the @sophagus. The alimentary canal offers no great peculiarities. The 
specimens were all very much stretched, and I am not certain if the form of the 
csophagus will prove constant. However, the contractions at the septa were much 
smaller than in any other species. The cesophagus from somite ix narrowed down 
toward somite xii, here it began to gradually increase in width, but the sacculated 
intestine begins evidently first in xvii, increasing in width gradually backwards until 
it reaches the region between xxvii and xxxy, where it suddenly narrows and con- 
tinues as narrow to the end of the body. 
Spermatheca (figs. 42 and 43). There is one pair in ix, opening between viii 
and ix, of the same general appearance as in Deltania Troyeri with minor character- 
istic details. The main sac is ovoid and somewhat lunate, pointed, with very smooth 
outline and with no trace of warty excrescences. There are two diverticula affixed 
halfway between the base and the glandular part. They are much smaller than 
those of Deltania Troyeri, being less than one-third as long as the main spermatheca, 
while in Deltania Troyert the diverticula are one-half or more as long as the main 
spermatheca, and affixed to the muscular part close to the base. The spermathece 
open in front of the Ist setee and are situated much closer together than those in 
D. Troyeri. The opaqueness of the spermatheca is the same as in the latter species. 
There is, however, a decided difference in the location of the spermatheca. In 
D. Troyer they are situated so far apart that they do not touch the ventral ganglion. 
In D. Benhami, however, they crowd it, this approach being caused partly by the 
closer proximity of the ventral or inner couple of sete, partly by the situation of the 
spermathecal pores which in our present form are more ventral to the sete. 
The sperm-sacs (fig. 41) are of a very characteristic form. They are larger in 
proportion than those of D. e/egans, but not quite as large as in D. Troyeri. There are 
two pair, one each in ix and xii, and they do not connect with each other. 
Each one consists of a very large flesh-like lobe, at the base of which are seen half a 
dozen smaller and globular saes, all connected at the place of adherence to the an- 
terior septum. These different lobes, the large one as well as the small ones, are 
full of rounded, oblong or irregular spermatophoric sphzerules. The sperm-sacs do not 
by far fill the somites. The form of the sperm-sacs varies to some extent, but the 
main character is the same in all, a large, rounded or flask-like lobe, at the base of 
which are several smaller ones. 
Spermduct and ciliated rosettes as in D. Troyeri. The prostate offers the char- 
acteristic of having the lower part of the glandular sac considerably swollen, conical 
and gradually diminishing in size towards the apex, which again is slightly enlarged 
like a knob. There is only one long slightly bent or almost straight seta in each of 
the penial seta-sacs, both setee opening on a small papilla, and which as far as [ can 
see more resembles that of D. Troyeri than D. elegans. The blood is very pale yellow, 
paler even than in the other species. There are three strongly pulsating hearts in
