cirrus sac runs up by the side of the ventral sucker, and contains 
bes.des the anterior portion of the vesicula seminalis a pars 
prostatica and cirrus. The male duct opens into a roomy, oval 
genital sinus. The outer genital pore lies in front of the ventral 
sucker; it sometimes appears median and sometimes on one side. 
The ovary is somewhat heart-shaped, and lies in front of the fore 
testis, but separated from it by a small space. A very Urge shell 
gland is present masking the other female organs, so that as" I have 
not yet made any sections of the worm, their exact relations have 
not been made out. There is a long pear-shaped receptaculum 
semmis and a Laurer's canal. The vitellarian duct opens into the 
oviduct close to the shell gland. The uterus has few loops, and 
occupies the space between the ovary and the vesicula seminalis 
then it runs forward as a rather inflated vagina to open by the 
side of the male duct into the genital sinus. The eggs are not 
numerous (20-40), and measure 0-10 mm. in length/ The vitel- 
lana are well developed, and reach from nearly the posterior end 
of the body to the level of the centre of the ventral sucker. They 
fill up the space between and behind the testes, and cover the 
intestinal lobes ventrally. 
From the above description it will be seen that this worm eon- 
forms m most ways with the sub-family LepocrtadiUt* as given by 
Oohner. However, it differs entirely from all the so far known 
members by pharynx-like oral sucker and its very largely developed 
shell gland. The long oesophagus is also at variance (as in my 
Lepodora elongata) with the Lepacr«,diin«. At first sight it is very 
hke Dvtomum bacillare (Molin), but differs from this little known 
species in several points, notably the vesicula seminalis, which in 
that worm is completely within the cirrus sac. 
For this worm I suggest the new genus Pharyngora, which mav 
be characterised as follows :-Long narrow worm, body covered 
th spines. Oral sucker formed like a pharynx. Small ventral 
deer. Long and very contractile prepharynx and oesophagus, 
testmal lo es reaching to end of body. Excretory vesicle v^ery
