![also ]be recognised. In the Suidas, more especially in Dicotylea, a fissure runs transversely outwards from the mesial longitudinal fissure; at first sight it might be taken for a crucial fissure, but on closer observation it will be seen to join the coronal fissure, 6 Fig. 28. —Vertex view of brain of Dicotylcs torquatus (Peccari). and not to be bounded by a sigmoid gyrus. When the sigmoid gyrus is absent, I do not think that this or any other transverse fissure should be regarded as homologous with the cruciate fissure in the Carnivora. The mesial surface of the ungulate cerebrum possesses a dis- tinct splenial fissure, which is frequently prolonged backwards and downwards to the tentorial surface; in many species, as in Phacochoerus and the common Pig (fig. 30), it is not continued forwards into the genual fissure, but is separated from it by a bridging convolution. In the Horse and Rhinoceros,-^ the ^ Owen described and iigured the brain of the Indian Rhinoceros (B. unicffrnis) in Trans. Zool. Soc, 1850, and Garrod figured the brain of the Sumatran Rhinoceros in Trans. Zool. Soc, vol. x. pi. Ixx., and in Collected Scientific Papers. The brain of the Hippopotamus has been described by Peters {Monats. d. Berliner Akad., 1854); Gratiolet, Paris, 1867 ; Macalister, Proc. Roy. Irish Acad., vol. i., 1873-74 ; Garrod, Trans. Zool. Soc, vol. xi., and in Collected Scientific Papers.](https://iiif.wellcomecollection.org/image/b21467304_0034.jp2/full/800%2C/0/default.jpg)
