Gulo.—The brain of this animal is only known to me throughthe description and figure of the cast of the inside of its skull givenby Professor Gervais *. He says :— Je ny retrouve pas, dumoins sur le moule intra-crauium, le dedoublement des deuxcirconvolutions superieurs caracteristiques du Galictis tar- The cast shows signs of tbe presence of an Ursine lozenge,which seems to be much, elongated antero-posteriorly; also of agreatly expanded and convoluted anterior limb to the sagittalgyrus, as well as of a longitudinal grooving of its middle and hinderpart. I can say nothing, of course, as to the inter-relationsbetween the hippocampal and sagittal gyri. Mustela.—
