Taeniae of Birds.* * * § — Dr. 0. v. Linstow lias a few notes on Taenia 
malleus , a Taenia without copulatory organs, and two new Oysticerci ; 
the last belong respectively to the Taenia setigera of the Goose, and 
T. brachycephala of Machetes pugnax ; the Cysticercus of the former 
lives in Cyclops brevicaudatus, and that of the latter in C. crassicornis. 
Notes on Parasites.f — Prof. A. Railliet first calls attention to a 
specimen of Cysticercus pisiformis with six suckers, a rare occurrence, 
of which but few examples have been noted. This arrangement is 
coincident with a trihedral form of the chain of the adult Taenia. From 
the small intestine of a rabbit he has lately taken a tapeworm which 
was remarkable for the slate colour of the greater part of the body ; 
though reduced by immersion in alcohol, the coloration was still very 
distinct ; the worm appears to be an example of Anoplocephala cuni- 
culi. The coloration is due to tine pigment granulations which are 
almost uniformly distributed in the parenchyma, and it is probable 
that it is due to the absorption and decomposition of haemoglobin, for 
the rabbit was suffering from a number of small ulcers due to stron- 
gy le s. 
Four specimens of Dipylidium caninum showed not fenestrations, as in 
the cases recently described by Neumann, but one or two lateral hollows, 
the cause of which remains quite obscure. Three joints of this tapeworm 
have been observed by the author in the anal glands of the Dog. 
Cysticercus tenuicollis has been found in a Kid from four to six weeks 
old ; the case is of interest, not only from the youth of the host, but 
from the advanced stage of development reached by the parasite in the 
liver and lungs. The same species, which is known to infest various 
Ruminants, is now recorded from Oryx beisa. 
In noting the occurrence of Taenia tenuirostris, which has been found 
in various wild Ducks and other birds, in the domestic Goose Prof. 
Railliet takes occasion to form two new genera ; Drepanidotaenia is for 
those of the type of Taenia lanceolata , of which the rostrum is armed 
with a simple crown of uniform hooks, of which one part is much longer 
than the other, while Dicranotaenia is for those of the type of T. coronula , 
in which the uniform hooks, which are arranged in a simple crown, have 
the two halves equal or subequal. 
Cysticercoid in Freshwater Calanid.J — Dr. J. Richard detected in 
Eurytemora lacinulata a cysticercoid which appears to be identical with 
the one found by Mrazek in Cyclops agilis ; this is the first time that a 
cysticercoid has been reported from a freshwater Calanid. 
Structure of Solenophorus.§ — Dr. C. Crety has given a detailed 
account of Solenophorus megacephalus Creplin, describing the two strata 
of the cuticle, the subcuticula, the parenchyma, the muscular system, 
the calcareous bodies, and the nervous system. Regarding an anterior 
commissure and two main lateral nerves as the primitive type of nervous 
system in Cestodes, the author contrasts the simple forms like Amphiline 
with more differentiated forms like Solenophorus.
