ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 31 



Oasterostomum gracilescens Rudolphi from the brain membranes of 

 (ladidge, with its final host in Lophius ; Gasterostomum sp. from the 

 muscles of the plaice, and another from the cockle which also contains 

 Gerearia fissicauda. Among the Cestodes noted are the following : 

 Dibothrium (= Bothriocephalic) punctatiim Rudolphi in brill, etc. ; 

 Tetrarhynchus tetrabothrius van Beneden from the pike and dogfish, and 

 T. erinaceus van Beneden from the gurnard. The author also notes 

 Echinorhynchus acus from the haddock, and Lymphocystis johnstonei 

 Woodcock (a sporozoan) from flounders. Pearl-like concretions in 

 gurnard, etc., are probably due to Tetrarhynchus cysts. 



New Bilharzia in Man.* — Looss points out that Schistosoma cattoi 

 described by John Catto (1905), is the same as Schistosomum japonicum 

 described by Katsurada (1904). It is remarkable that the same new 

 parasite should have been found about the same time at Singapore and 

 in Japan. Looss gives some account of the new form. 



Scolex of Idiogenes.f — N. Cholodkovsky has found a species of 

 Idiogenes (I. grandiporus from Otis tetrax) with a well-developed scolex 

 with 104 hooks, a discovery which makes it possible to refer this genus 

 to its place in the system, namely, close beside Dilepis. 



Cestode Studies.! — Th. Pintner gives an account of the "frontal 

 glands" which develop on the wall of the bladder-worm stage of 

 Rhynchobothrius adenoplusius sp. n., and extend over the scolex- 

 primordium. Their primary openings are on the most anterior margin 

 of the scolex ; they attain their maximum activity when the scolex is 

 fully formed within the bladder ; they afterwards begin to atrophy. 

 Over the whole surface of the larval body there are very numerous 

 unicellular glands — which the author calls " Finnendriisen." The 

 integument of the animal is fully discussed, and there are notes on the 

 structure of Amphilina and the cuticle of Tainia saginata. 



Mammalian Cestodes. § — J. Bourquin gives a detailed account of the 

 anatomy and histology of Bertia studeri, B. elongata, and B. plastica, 

 parasites from Troglodytes niger and Galeopithecus volans. The paper 

 includes a discussion of the differences of the first-named from 

 B. mucronata and B. conferta, to which it bears several resemblances. 



Cestodes from a Porpoise.|| — E. Linton describes bladder-worms 

 from the mesentery of Lagenorhynchus acutus, probably the same as 

 Chamisso found long ago, and Rudolphi described in his synopsis as 

 Gysticercus delphini. Another form which Rudolphi described in his 

 history of Entozoa as Gyst. delphini should be referred to the genus 

 Phyllobothrium. The final stage of the form here discussed, for which 

 the title Tmiia chamissonii is proposed, is probably in another mammal, 

 e.g., Orcinus orca.
