    Chromosomes sexuels géants chez un Campagnol,Microtus agrestis L (1949)

    Notes: Summary In the vole,Microtus agrestis L., there are 46 chromosomes as in the twin-species,M. arvalis Pallas. In striking contrast to this last animal, the sexual chromosomes, studied in the last spermatogonial divisions, are of gigantic size (X metacentric = 8–9 µ;Y acrocentric = 5–6 µ). The identification of theX is proved by the analysis of marrow-smears of the female. It is expected that several problems concerning the mode of attachment and the type of association betweenX andY can be resolved by the study of that most interesting rodent.

    Chromosomes de Muridae (II) (1952)

    Notes: Summary Following the new squash-technic ofMakino andNishimura, it is now possible to work more quickly and with more accuracy on the chromosomes of mammals. The author has established the cytological conditions in seven species of Muridae and elucidated some doubtful points belonging 15 other species.Microtus arvalis, M. orcadensis andM. incertus have the same formule and must be considered as very akin. The chromosomic set ofClethrionomys gapperi (North-America) doesn't differ from that ofC. glareolus (Europe). Three genera of Gerbillinae exhibit sex-chromosomes of the type found in palearctic Cricetinae. ByArvicola scherman andMicrotus nivalis a reinvestigation shows thatX andY are both metacentric. It seems preferable to putNeotoma floridana andPeromyscus leucopus, likely with the other genera of nearctic Cricetinac, in a special under-family, for they bear no cytological ressemblance with the true hamsters of the Old World.Dipodomys merriami, an Heteromyidae, has 70 and not 86 chromosomes (Cross, 1931). There is in none species coexistence of pre- and post-reduction, although pictures of chiasmas may be sometimes observed. The conception ofKoller andDarlington does not agree with the facts.

    Notes: Summary The chromosomal sets of five species ofPerlodidæ (Plecoptera) are given in the present paper. The sexual chromosomes belong to three distinct types:X-O,X 1-X 2,X 1-X 2-X 3. The author shows that these three types are likely derived from the most primitive patternX-Y, by translocation and inversion.

    Notes: Summary The author has studied 18 species ofMuridae. Only two had previously been investigated. The main results are summarized in a list (see above). Statistically, these observations confirm the statement that more than half of theMuridae have a diploid number between 40 and 56.

    Cytologie comparée des Muridae. L'origine des Ellobii (1956)

    Notes: Summary (1) The present paper deals with the chromosomial cytology of 11 species and underspecies ofMuridae. (2) The diploïd number being the same (2N=42), there are striking differences between two species ofBandicota, B. indica showing about 20 big metacentric chromosomes which are lackingB. bengalensis. (3)Meriones blackleri is characterized by 72 chromosomes, the species previously described possessing either 44 or 60 elements. (4) The study ofPhenacomys ungava confirms the view that 56 (54) is the primitive number in theMicroti. There is an interesting parallelism between the morphological and the cytological data. (5) A missing link betweenMicroti andEllobii has been found inMicrotus oregoni which possesses 17 chromosomes, its digamety belonging to the typeX-O, X-X. (6) Owing to the fact thatM. oregoni is more fossorial than the otherMicrotus, it is a morphological intermediate betweenMicroti andEllobii. (7) The genusChilotus (Baird) is also fully valid.

    Un cas nouveau de polymorphisme chromosomique intraspécifique chez un Mammifère (Leggada minutoides Smith. Rodentia-Muridae) (1963)

    Notes: Summary The African mouse,Leggada minutoides Smith, shows a chromosomal polymorphism: a first male (Coast of Ivory) had 32 chromosomes; theX is a big metacentric, theY a big submetacentric and the autosomes are acrocentric, with the single exception of the biggest pair which associates two submetacentric elements. By a second male (Congo), 33 chromosomes are found, amongst them only one big submetacentric autosome. This statement and the odd diploid number shows clearly that we have to deal with an heterozygot, two acrocentric elements representing respectively one arm of the submetacentric autosome. Now, we may be sure that this male belongs to a population built of individuals having 32, 33 and 34 chromosomes. The origin of such a population must have arisen in a primitive population where 34 was the diploid number, through a centric fusion. Such cases pose the question of the balanced chromosomial polymorphism and of the adaptative value of each formula6.
