CALIFORNIA EUDRILIDA, Do 
Septal Glands (figs. 26, 27, 29). When the worm is laid open and the cavity 
viewed from above, it is seen that there are 4 pair of septal glands surrounding the 
cesophagus in somites v, vi, viiand vii. In this view the anterior gland appears the 
largest, and the posterior one in viii the smallest. This is, however, only an illusionary 
appearance, caused by the position of the glands. There is in reality not any very 
considerable difference in their size, as may be seen when separated and spread out. 
Seen ina slightly eccentric longitudinal section, the gland in vi appears the largest both 
above and below the cesophagus, though in some sections the lower part is not as large 
as the lower part of the gland in vii. The anterior gland in y is short but broad. The 
one in vil is larger than those in v and viii, but smaller than the one in vi. The 
upper part of the gland in viii is larger than the corresponding part of y, the lower 
part of the latter being the smallest. As will be seen, all the glands are developed, 
both superiorly and inferiorly, as regards the csophagus, but the glands on either side 
in the somite do not connect, but only touch. There is a slight, but irregular lobing 
of the glands, frequently unequal on either side, as one gland may be almost entire, 
while the other again is furnished with three indentations. On the under side of 
each main gland there is a smaller lobe, almost entirely separated from the rest (fig. 
29). The glands are furnished with blood from the subcsophageal longitudinal blood- 
vessel which projects a branch to each gland, on which it again divides in two or 
three parts (fig. 29). I may add that the septal glands are very large, almost filling 
the respective somites, and as compared with those of De/tania elegans, about three 
times as large, considering however the relative size of the two species. The glands 
are nearly similar to those of Deltania Benhami, but with more unequality as to size. 
Salivary or Pharyngeal Glands (fig. 26). These glands resemble those of the 
preceding species, Deltania elegans, in general appearance. There are two very long 
glands behind the brain, attached on the underside of the two long muscular bands 
which stretch upward. The anterior one of these is the smallest and rather short. the 
second in order from the brain is the longest. The posterior gland, which forms the 
posterior projection of the pharynx, is much shorter, more compact and rounded 
than the corresponding gland in Dedtania elegans. The whole mass of glands projects 
much less posteriorly than the glandular mass of the pharynx in that species. 
Spermatheca (figs. 30, 31, 32 and 39). These organs are prominent and char- 
acteristic of the species. There is one pair in somite ix opening in the inter- 
segmental groove between that somite and viii. The external pore is in front of the 
inner couple of setze, but not interior to the sete. The organs are thick, opaque and 
of the form of pointed saes, each one with two diverticula, one on each side, which 
connect with the main sac close to the external pore. The outline of the sae is irreg- 
ular in some places, toward the inner apex assuming the appearance of one or more 
warty diverticula, which, however, never assume the size of the diverticula. Of these 
latter there are one pair which are slender, cylindrical, of more or less irregular out- 
line with the apex sometimes slightly wider, sometimes helix-like, turned on itself. 
The lower part of the spermatheca is muscular, but this muscular part is quite small,
