SUilllAKY OF CORBENT RESEARCHES RELATING TO 
and cases have also been observed by Wernicke * * * § and R. Blanchard. | 
Among the numerous contributions of the latter is onej on the Helminths 
of Anthropoid Apes ; the Chimpanzee and the Orang are infested by 
closely allied species of Bertia ; this genus appears to be confined to 
Anthropoids. Railliet § has observed that Ccemirus serialis may live in 
French rabbits for more than two years. The question of the bifurca- 
tion of Cestodes is discussed by R. Moniez.|| 
Tailed Cysticercoids.il — Dr. 0. Hamann describes two new tailed 
cysticercoids from Gammarus pulex. It is likely that the adult forms 
which he calls Tsenia bifurca sp. n. and Tsenia inteijra sp. n. are para- 
sitic in birds. The most interesting fact about these cysticercoids is 
their likeness to cercarise. In a postscript Hainan refers to Mrazek’s 
discovery of a similar cysticercus (C. Eamanni ) in Gammarus, and to 
the fact that the cysticercoids of T. sinuosa and T. tenuirostris (discovered 
by Hamann in Gammarus ) occur also in various species of Cyclops, and 
vary slightly according to their hosts. 
Solenophorus and Duthiersia.** — Drs. F. S. Monticelli and C. Crety 
seek to show by a detailed comparison of these tapeworms — character- 
istic respectively of Boidae and Varan i das — that they represent two 
genera distinct from one another. They are to be ranked in a sub- 
family Solenophorinas, beside Bothriocephalidae, Lingulidae, &c., in the 
family Dibothria. They give a critical account of Solenophorus mega- 
cephalus Creplin and Duthiersia fimbriata Diesing. 
Taenia inermis fenestrata. ft — T>r. A. Maggiora obtained from a 
patient a specimen of the somewhat rare form of tapeworm known as 
Tsenia fenestrata and this he was able to identify as being an anoma- 
lous form of Taenia mediocanellata, a species very liable to malformations. 
The length of worm obtained was 68 cm., and the number of segments 
52. The genital openings were lateral and alternate ; the uterus had on 
each side about 20 branches with dichotomous subdivisions ; the mature 
eggs were oval and corresponded in size to those of mediocanellata. The 
identification rested with about 20 normal segments, the remainder 
showing the malformations characteristic of Tsenia fenestrata. The 
changes began as small pits and these towards the more mature end of 
the worm became larger and larger both in breadth and depth until the 
last 15 segments were reduced to a mere edge, thus causing them to 
resemble a ladder. 
Examination by means of a lens of segments apparently normal, 
showed the presence of numerous white spots and projections — a fact 
already noted by Danysz. The author not only corroborates Danysz’s 
observation, but accepts his view about their being the cause of tbe 
perforations. The spots are, according to this view, degeneration foci
