Two new Taeniae from Apes.* * * § — Herr K. Meyner describes two new 
Taeniae found in apes. The first (T. mucronata sp. n.) was obtained 
from the intestine of a howling monkey ( Mycetes niger). It has about 
600 short joints in a length of 14 cm. The neck is short and the 
unarmed head provided with four large suckers. There is much pigment 
about the vertex of the head. There is a genital apparatus in each 
segment, and the pore is lateral and irregularly alternating. In the 
ripe proglottides is a canal, running transversely and almost straight, 
with numerous dilatations. The eggs, which have three coats, are 
0*036 mm. long. This Teenia belongs to the Anoplocephalina and 
probably to the genus Bertia Blanch. 
The second species ( T. conferta sp. n.) was obtained from an Indian 
monkey ( Macacus radiatus ). It is only 8*4 cm. long, with short joints, 
and is quite unarmed. The genital pores are marginal and irregularly 
alternating. 
Bothriocephalus Zschokkei sp. n.f — Herr 0. Fuhrmann describes a 
new species of tapeworm, Bothriocephalus Zschoklcei, of which two speci- 
mens were obtained from the intestinal canal of Ardea stellaris, a fish- 
eating bird. The lengths of the strobiles were 25 and 30 mm., and the 
breadth of the segments near the middle of the worm 2*5 mm. A 
singular characteristic of this species is that in the anterior half the 
proglottides are broader than in the posterior half. The scolex is 
triangular. In the text two bothria are described, but in the illustration 
the sucker is represented as horseshoe-shaped. The number of joints is 
about 80. The muscular system is strongly developed and presents 
some striking peculiarities, five layers being described. The water- 
vascular system is well developed, and the number of anastomoses 
numerous. The nervous system consists of two thick longitudinal 
bundles, which in the scolex unite at a ganglion. The sexual openings 
lie on the ventral surface. The reproductive organs are described in 
detail. The ova are 0 * 07 mm. long and 0 * 029 mm. broad. 
Cysticerci in a Dog’s Keart.J — Hr. W. Lindemann found 20-25 
vesicles, each the size of a hazel-nut, filled with clear fluid, in the muscle 
of a dog’s heart. From the inside of each bladder grew a swelling the 
size of a hemp-seed. This was found to be a tapeworm scolex, provided 
with a double circle of hooklets and four suckers. The hooklets, 26-28 
in number, had two long fangs. On the whole these worms seem to 
resemble Cysticercus cellulosse. After alluding to the rarity of the 
occurrence of the hydatid form of tapeworm in dogs, the author goes 
on to suggest that the reason of this is to be sought in a special 
immunity. 
Morphology of Proboscis in Tetrarhynchi.§— Dr. Th. Pintner con- 
cludes that the proboscis of Tetrarhynchi and perhaps also some of the 
suckers of Taeniidae are referable to the apical auxiliary suctorial grooves 
of the attaching disc in the Tetrdbothrium type. Both have the same
