septa in front are not tied together with “tendons,” as is so 
often the case in earthworms. After these thickened septa 
there are three very delicate ones which separate segments 
10/13. After them, again, are a series of stronger septa, but 
nothing like so much thickened as the anterior set already 
described. The former commence with that dividing 
segments 13/14, and the next few (say, five or six) are also 
very strongly marked, gradually fading away in successive 
segments into the delicate septa which are usual in the 
posterior region of the body. 
The pharyna is attached to the parietes by a number of 
rather flat muscle-bundles well marked out as such. The 
wsophagus is thin-walled and passes into the gizzard suddenly ; 
there are no muscle-bands connecting the cesophagus with 
the gizzard, termed by Cognetti “‘ nastri””—that is, ribbons, as 
I suppose *. The gizzard, as in all these worms, lies in the 
sixth segment. The calciferous glands are stout and furnished 
with a conical and separated appendix, which is often, but 
not always, blackish, due, as has been pointed out, to blood- 
vessels. ‘he calciferous glands are in segments 7-14 in- 
clusive, and thus number the usual eight pairs. They arise 
ventrally from the cesophagus and end dorso-laterally. The 
intestine begins in segment 18. It is remarkable for a very 
large typhlosole, which seems to resemble that of 7h. columbz- 
anus, but to differ from it in many details, indicative, as 
I think (among other characters), of specific difference. I 
examined the typhlosole in two specimens. It is very large 
and thick, and has a corrugated appearance, being furrowed 
and thus divided into lobes. The typhlosole begins a little 
‘way down the intestine and ends about halfway down the 
body. It has thus a length of something like one quarter of 
the entire length of the worm. It also begins and ends 
abruptly. The beginning and ending of the typhlosole 
consists of a thick and quite smooth fold of the dorsal gut- 
wall. It rapidly increases to a considerable depth and 
becomes covered with secondary folds, divided—necessaril y— 
by corresponding furrows. Of these, which are rounded 
angled rhomboids in form, there are three to four on each side 
to a vertical row, and one median ventral. 
In front of and behind this thick and complex typhlosole I 
did not detect a slight ridge, such as might represent an 
unspecialized region of the fold. I am inclined to think that 
the typhlosole is limited as here described. Michaelsen’s
