species. Oysticerci from a human corpse were swallowed by Redon, 
pigs, and dogs ; it was in Redon only that the strobila stage was deve- 
loped. Lortet is of opinion that the form obtained was no other than 
I'amia solium. 
Pagenstecher (20) has observed the presence of nine examples of 
Arhyncotcenia critica (sp. n.) in the strobila stage, in a cyst found on the 
liver of Hyrax capensis, Schreber. In elucidation of the attainment of 
sexual maturity prior to ingress into the intestine, the author cites the 
history of Cysticercvs fasciolaris from the liver of the mouse, and the 
condition attained by Tcenia crassicollis in the cat^ and other Felidce. 
In a cyst in the neck of Myopotamus coypus, Geoffroy, Redon found a 
Ccenurus serialis, Gervais, with two rows of sixteen hooks, one smaller 
than the other, and both smaller than those of C. cerebralis ; and he con- 
cludes that this is the same species as that found by Cobbold in Lemur 
macaco and Sciurus sp. (American), and by others in the hare. 
G. J. Romanes writes (Nature, xv. p. 276) on tape-worm in rabbits. 
G. Zograf is reported by Iloycr (in Protocollo dor Sitz. der Section fiir 
Zool., Versamml. russischer Naturforschor, &c., Z. wiss. Zool. xxviii. 
pp. 393-39G) as describing the structure of Tvkvnopliorus nodulosus. The 
longitudinal muscles of the neck are divided into four bundles ; the 
cuticle is villous ; no shell-gland, 
Du Plessis (8) describes a new Mesostomum^ with large and well- 
developed auditory capsules, not hitherto known in this genus. In a 
second note, “ Sur le Vortex lemani (tom. cit. pp. 254-259), he states his 
disagreement with Graff’s [Zool. Rec. xii. p. 634] opinion as to this form 
belonging to the genus Planaria, but he leaves Graff to find a new 
generic name ; jn his own opinion it is intermediate between the JRhahdo- 
cfcla and Dendrocosla. 
The second edition of Davaine (7) contains 110 for the 88 figures of 
the first edition (1860), and a supplement, in which are given details to 
bring the subject up to the present state of science. 
Landois (10) gives an interesting account of a visit to a leech farm. 
The structure of Geoplana traversi, and of the Australian new species, 
and of DolicJioplana striata is described by Moseley (17) in some detail. 
Llmacopsis^ Dicsing (with eye-bearing frontal tentacles), probably 
differs much from the Geoplanidic^ which appear to form a natural 
family. The New Zealand forms seem to bo most closely allied to the 
South American, and the Cape species to the Indian land-Planarians. 
The ova are found in chitiuous capsules, and develop in them into free 
embryos ; cf, Dendroccdum lacteum. 
Linstow(12) is led to the conclusion that Tetracotyle and Diplostomum 
are larval forms of Holostomum ; he traces the life-history of II. cornu- 
copice, the mode of which is shown to be intermediate between that of 
Distomum, Monostomum, and Amphistomum, in which sporocysts are 
developed, and Gyrodactylus, Diplozoon, Polystomum, &c., in which the 
embryos resemble the mother. 
Donnadieu (supi'd, p. 9) has examined the development of Ligula, and 
finds that the ovum is developed in water, and that the scolex passes into 
the digestive tract of fishes (chiefly Cyprinoids), thence reaching the peri-
