vent, and carries on its back nine large spherical eggs, 10 milli- 

 metres in diameter, each containing a little frog distnictly visible 

 throuoh the transparent membrane which at this stage constitutes 

 the eo^o--capsule. The little one, with the abdomen, tumid with 

 yolk,1;nrned towards the back of the mother, and the limbs folded 

 against the belly, is connected with the membrane by two string- 

 like cords on each side, proceeding from the throat, as figured in 

 I^ototrema cornittii,m 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 Geratohyla simply stick to the back, leaving shallow hexa- 

 gonal impressions on the much-thinned dorsal skin, through which 

 the neural processes of the vertebrae 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 Gerato- 

 hyla belongs, AmjMgnathodon gueniheri Blgr., is provided with 

 a dorsal ponch as in Nototrema. We therefore find among the 

 Tailless Batrachians with teeth in both jaws the same adaptations 

 for the protection of the ofispring as occur among the Hylidee, 

 where Hyla goeldii Blgr. stands, in this respect, in the same 

 relation to Nototrema as Geratohyla biobahcs to Amjjhignathodon. 



" 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.E.S., exhibited on behalf of the " Flower 

 Memorial Committee " a bust of the late President of the Society, 

 Sir William Henry Flower, K.O.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 immigra- 

 tion 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 having
