HOLDING ON THE [June 16, vent, and carries on its back nine large spherical eggs, 10 millimetres in diameter, each containing a little frog distinctly visible through the transparent membrane which at this stage constitutes the egg-capsule. The little one, with the abdomen, tumid with yolk, turned towards the back of the mother, and the limbs folded against the belly, is connected with the membrane by two stringlike cords on each side, proceeding from the throat, as figured in Nototrema cornutum Blgr. (P. Z. S. 1898, pi. xviii.), and which serve to convey the blood, for the purpose of respiration, to the vascular, allantois-like membrane. The resemblance which the young bears to that of Nototrema cornutum is very striking, except in the breathing-organs, which in the latter, as well as in N. oviferum and N. testudineum, form funnel- or bell-shaped appendages. Whilst in Nototrema the eggs are protected in the dorsal pouch with which the mother is provided, the eggs in this Ceratohyla simply stick to the back, leaving shallow hexagonal impressions on the much-thinned dorsal skin, through which the neural processes of the vertebra? project to such an extent as to leave marks on the vitelline sacs with which they are in contact. " A near ally of the Hemiphractida?, to which family Ceratohyla belongs, Amphignathodon guentheri Blgr., is provided with a dorsal pouch as in Nototrema. "We therefore find among the Tailless Batrachians with teeth in both jaws the same adaptations for the protection of the offspring as occur among the Hylicla?, where Hyla goeldii Blgr. stands, in this respect, in the same relation to Nototrema as Ceratohyla bubalus to Amphignathodon. " The specimen exhibited was obtained at Santo Domingo, Carabaya District, S.E. Peru, 6000 ft. Mr. Ockenden is unable to give any particulars as to the conditions in which it was found, he not having been the actual discoverer of the remarkable specimen." Mr. F. E. Beddard, F.R.S., exhibited on behalf of the " Flower Memorial Committee " a bust of the late President of the Society, Sir William Henry Flower, K.C.B., D.C.L., F.R.S., which had been executed by Mr. Thomas Brock, R.A., and which would ultimately be placed in the British Museum of Natural History. Mr. F. E. Beddard also exhibited and made remarks upon sections of the ovary of Thylacinus which showed the immioration of follicular cells into the ova. Mr. R. E. Holding exhibited some skulls of the St. Kilda four-horned Sheep, and made the following remarks: " The small black Spanish or St. Kilda four-horned Sheep is interesting not only on account of the curious legend as to its first appearance on the island of St. Kilda, but from its havino- |
