inwards, and acting as a support to tlie edge of the descending valve, 

 the wall of the lorica being dilated laterally immediately behind this, 

 in optical section bristle-like, valve-rest ; body pedicellate, hyaline, 

 projecting when extended one-third its entire length beyond the 

 orifice of the lorica ; pulsating vesicle anterior, contracting once in 

 fifteen seconds. 



Flagellata,* — J. Kiinstler's extended article on this subject appears 

 in the first part of the French Zoological Society's Bulletin. This 

 has only just been distributed to Societies exchanging, although pur- 

 chasers have long been in possession of it. It is much to be wished 

 that some of the foreign Societies could be induced to forward their 

 publications (as the Eoyal Microscopical Society does) immediately 

 on issue, instead of one, two, or even three years after date, as is now 

 often the case. The present article has already been anticipated, and 

 a brief extract of it appeared in Vol. II. (1882) p. 62. We may add 

 here that it comprises the following parts : — 



(i) Introduction and historical view (in which the various systems 

 of classification are discussed). (2 and 3) Descriptive part (which 

 deals with the exterior, flagella, integuments, physiological considera- 

 tions, digestive apparatus, general cavity, vestibulary tube, contractile 

 vesicle, oculiform point, reproductive apparatus, and development). 

 (4) General considerations (cell, and protoplasmic spherule). (5) Sys- 

 tematic considerations. (6) Bibliography. 



A " further contribution " on the same subject t was abstracted at 

 p. 518 of Vol. II. (1882)4 



Prof. O. Biitschli § ridicules the author's views of the organization 

 of the Flagellata, and his description of the complicated structures 

 which he discovered in them in the way of stomach, intestine, uterus, 

 &c., and in particular depreciates the value of his observations by point- 

 ing out that the new genus Kilnckelia gyrans which he founded and 

 of which he gives elaborate woodcuts, is, in fact, neither more nor less 

 than a Gercaria ! 



MicrosporidiEe or Psorospermige of Articulates.il — E. G. Balbiani, 

 as the result of investigations on their mode of reproduction, proposes 

 to designate as " Microsporidia " or Psorospermiee of the Articulates 

 the " corpuscles " of the silk-worms which he considers to be nothing 

 else than the spores of an organism having affinities with those for 

 which Leuckart proposed the name of Sporozoa, which includes 

 already (1) the Gregarinidse, (2) the oviform Psorospermi^ or 

 Coccidise, (3) the tubuliform Psorospermiae or Sarcosporidiro, and (4) 

 the Psorospermise of Fishes or Myxosporidise. 



The microsporidia of Attacus Pernyi is formed when young of a

X In his first paper the author throughout calls the species to which his 

 description refers, Cryptomonas ovata Ehrbg., though at the same time he ex- 

 presses his opinion that his species was in reality a new one, Heteromitus olivaceus. 

 In the second paper the latter name only is used.
