12t; MEMOIRS OF TTIF QUKFKHLAND MUHF.UM, 
The right pore is placed at the ventral-most corner and slightly nearer the posterior 
than the anterior edge of a somewhat diamond-shaped, flattened, glandular area 
which extends from just ventral of a to a distance beyond b about equal to ah. Between 
the two papillic there is a well-defined groove which bifurcates at the papillae to 
include about a half or less of them in the fork so formed. The posterior limb of each 
bifurcation is the continuation of a deeper, narrower groove wdiicli forms the posterior 
portion of the main one. 
The female pores are paired and close together on xiv., anterior of the setae 
ring. 
The spermathecal pores are two pairs situated at the anterior edge of viii. and 
ix. in grooves 7/8 and 8/9. The setae are not visible on these segments, but the pores 
seem to be about in line with, or just dorsal of, a. 
On the ventral surface of segments viii.-xii. there is a glandular strip posteriorly 
bounded by the segment edge, anteriorly just clear of the central annulation furrow, 
and extending beyond b on each side to about half way between b and c. These strips 
have a definite deep pink colour. 
Internal Anaiomy . — Septum 0/7 muscular and thick ; 7/8 somewhat thicker ; 
8/9 considerably thicker than 7/8 but only about half as thick as 9/10 ; 11/12 
enormously thickened ; 10/11 and 12/13 less stout but still very thick, 12/13 being 
the stouter ; 9/10 a little thinner than 10/11 ; 13/14 about the same as 8/9. 
Gizzards Avell developed and bulbous in vi. and vii. 
Large intestine commences in xviii. There is in xi. a structure which looks 
like and probably is a calciferous gland ; it is unpaired and placed saddle-wdse on the 
intestine of which it embraces about tw'o-thirds. Vascular swellings present in 
xii.-xv. 
Last heart in xiii. 
The excretory system is micronephric with numerous micronephridia in each 
segment, which are ])ai'ticularly plentiful in the segments in front of xix. ; in xix. and 
from thence backwards micronephridia less numeroxis and tend to be aggregated in a 
transverse band in the middle of the segment. 
Testes and funnels paired and free in xi. There is a single pair of large, loosely 
granular seminal vesicles in xii. attached to the anterior septum of the segment and 
approximated above the intestine. 
Prostates paired in xviii., flattened, tongue-shaped ; they are comparatively 
small and lie on the floor of the segment. The duct is short and slender and joins the 
gland at the level of the imier surface of the body w^all. 
Penial setae absent. 
Ovaries and funnels paired in xiii.
