$The Edentata possess convoluted brains. The species which I have dissected are Dasypua sexcinctus and Cholcepua Fig. 13.—Brain of Dasypus sexcintus. 1, vertex view; 2, cranial surface ; 3, mesial surface ; 4, vertical transverse section. hoffmanni} In Dasypus ^ an antero-posterior fissure traverses 1 Tiedemanu has figured the brain of Bradypus didadylus (Icmcs Cerebri Simmrum, &c.); Rapp has described D. novemcinctus; W. H. Flower has floured Cholospus didadylus {Phil, Trans., 1865), Paul Gervais has figured {Nouvelles Archives dio 3htseum, r., 1869) the brains of Euphractus {Dasypus) villosus, Manis temmiiwld, Myrmecophaga jubata, Orycteropus capensis; Georges Pouchet {Journal de VAnat. and Phys., vols. v. vi., n.s., 1868, 1869) has figured the brains of Diouyx, Pangolin, and Bradypus; W. A. Forbes has figured the brain of Myrmecoplmga jit.bata {Proc. Zool. Soc, 1882, and in Collected Scientific Papers) In all these Edentates, except Dionyx, the pallium is convoluted, although the convolutions are more numerous in Myrmecophaga and Manis than in Dasypus In Manis there is apparently, from Gervais's figure, a well-marked Sylvian fissure and the fissure depicted by Forbes, l.s.s., fig. 3, in Myrmecophaga is doubtless also the fissure of Sylvius. = Fig. 13 is reproduced from my paper on the brain ot Dasypus scaxinctus in Jour.
