was mucli inflamed, were found a couple of pailfuls of Ascarides. There 
were none in the large gut. In the stomach was about another pailful 
of worms which had probably migrated there after death. 
Simondsia paradoxa in the Stomach of Wild Soars.* — Sigg. V. 
Colucci and L. Arnone found in the stomachs of three wild boars nume- 
rous Simondsia paradoxa. The males were not free in the stomach, for 
the middle part of the body lay beneath the mucosa from which the ends 
projected. The authors believe that Cobbold confused the male of 
Spiroptera strongilina with that of Simondsia paradoxa. The latter has 
not two spines and two lobes on the tail. The posterior end of the 
female is mulberry-shaped. The histology of the worms is described at 
some length. 
In the streams of the woods inhabited by the boars the authors found 
some nematode larvae 0 • 65 mm. long and 0 • 02-0 • 025 mm. broad, devoid 
of sexual organs but possessed of a digestive system very similar to that 
of Simondsia paradoxa. The posterior end is thick and globose. The 
authors believe that they had to deal with a female of Simondsia 
paradoxa . 
Helminthological Notes, f — Dr. M. Stossich notes seven worm- 
parasites from a large specimen of Orthagoriscus mola. The list includes 
AnchistrocepJialus microceplialus Rudolphi, Dibothriorhynchus gracilis 
Wagner, and Echinostoma lydise Stossich. 
In another paper f he records the occurrence of about eighty forms, 
e.g. Ichthyonema jiliformis Stossich in the ovary of Pagellus erythrinus 
and Trachinus draco , Strongylus ersilise Stossich in a python, Distoma 
vallei Stossich in Falco subbuteo, and so on.

Excretory Organs and Blood-Vascular System of Tetrastemma 
graecense.§ — Dr. L. Bokmig has a preliminary account of this freshwater 
Nemertine which he has found in abundance at the Botanic Garden at 
Graz. On either side of the body there is a system of clear, arborescent, 
and interconnected canals which extends through the whole length of the 
worm. At the anterior end of the body there is a single larger canal 
which ends in a fine closely-meshed plexus of very small vessels. The 
excretory organs may be considered under the three heads of terminal 
canaliculi connected with the terminal organs, connecting canals, and 
primary canals ; these are all briefly described. There is not the close 
connection between the nephridia and the blood-vessels in T. gracense , 
which Burger has described for the marine Metanemertines. 
The blood-vascular system consists of two lateral and one dorsal 
vessel ; anteriorly the latter opens into the right lateral vessel, and 
posteriorly into the anal commissure of the two lateral vessels.
