worms, the other with one. The body is elongated, cylindrical, tapering 
posteriorly ; there are 7-22 suckers in a mid-ventral row ; the pharynx 
is of medium size, the intestine simple and tubular, extending to near 
the posterior end ; the genital orifice is median, and ventral, in front of 
the anterior sucker ; there are two testes, in the middle region of the 
body, situated dorsally, one on either side of the intestine ; the ovary is 
nearly median, ventral to the intestine, in front of the testes, with an 
oviduct to the right ; yolk glands lie dorsally and posteriorly, and the 
duct passes on the right side to the oviduct ; the excretory pore is dorsal 
and posterior, the excretory vesicle forms two broad convoluted tubular 
trunks on each side of the intestine as far as the pharynx. The life- 
history and the adult form (perhaps in cat-fish or the like) are quite 
unknown. 
The Diclidophoringe.* — M. P. Cerfontaine has found on the gills of 
Labrax Lujpus a new species of Diclidophora — D. Labracis. He pro- 
poses to define a sub-family Diclidophoringe, within the family Octo- 
cotylidae, and including Diclidophora (Goto), Cyclobothrium (Oerf.), and 
Heterobothrium (Cerf.). These are characterised by the eight cupule- 
like suckers, each of which has a cruciform chitinous framework at its 
base. In Diclidophora , the suckers are stalked, the anterior suckers 
communicate widely with the buccal cavity, the alimentary canal 
anastomoses posteriorly and sends a ramification towards each sucker, 
the genital bulb has a crown of hooks with double points, the testes lie 
behind the ovary which has the form of a capital N with the left side 
most developed, the genito-intestinal canal opens into the right branch 
of the intestine at the level of the anterior part of the ovary, the seminal 
vesicle is median in front of the ovary. 
New Trematode.f — Dr. G. Brandes describes Fridericianella 
ovicola g. et sp. n., which was found on the eggs of a Brazilian fish — 
Arius Commersoni Lac. — famous for the manner in which the male 
hatches the eggs in his mouth. The new parasite seems to be most like 
Calceostoma , a genus of Gyrodactylid®, but it is in some ways very 
distinct. It measures 4-5 mm. in length by 1-2 mm. in breadth ; the 
anterior and posterior poles are slightly swollen, the latter bearing a 
terminal sucker, the former two glandular lateral pads. But most 
characteristic is a glandular and nervous pad projecting medianly on the 
right side of the body. 
Echinococcus multilocuiaris of the Brain.* — Hr. M. Bider de- 
scribes a case of Echinococcus multilocuiaris of the brain which occurred 
in a butcher, 53 years old, of the canton of Thurgau. The parasite 
was found in the right frontal lobe. The typical membranes, hooklets, 
and head, which were very frequent in a cyst the size of a pea, but 
less so in three ’ smaller cavities, left no doubt about the diagnosis. 
The multilocular character of the bladder-worm was also clearly mani- 
fested. The connection between the parasite and the blood or lymph 
vessels was not demonstrable. A comparison between the hooklets of the
