Dr. William Nicoll, M.A., F.Z.S., exhibited some preparations 

 from a Hare which showed an interesting and unique patho- 

 logical condition. The liver was extensively invaded with 

 calcareous nodules which were due to a parasitic JSTematode of 

 the family Trichotrachelidce. The worms were so coiled up that 

 they could not be extricated entire, but the ova, which were 

 present in enormous numbers, showed that they must belong to 

 a peculiar genus. The structure of the eggs was remarkable in 

 displaying a double- layered shell, with a markedly papillated 

 surface. No similar condition had been hitherto recorded from 

 the Hare or Rabbit, but an analogous condition had been met 

 with fairly frequently in Rats. It was still impossible to say 

 whether the conditions in the two animals were caused by the 

 same species of parasite, but experiments with a view to deter- 

 mining this were in progress. The Hare further showed a large 

 infection with Trichostrongylus retortceformis, and a slight, purely 

 intestinal, infection with Coccidium cuniculi. There were also 

 signs of recent parturition and of an inflammatory condition of 

 the uterus. Whether this or the liver disease was the cause 

 of death, which took place under remarkable circumstances, is 

 doubtful. 



Dr. CuTHBERT Christy, F.Z.S., exhibited part of a collection 

 of skins of mammals and reptiles obtained by him in Uganda, 

 which included those of the Antelope, Leopard, Civet, Hyrax, &c., 

 and drew attention to a rare form of Dendrohyrax, D, emini, 

 and to the skin of a melanistic form of the Civet. 



Dr. William Nicoll, M.A., F.Z.S., read a paper on Three 

 neAv Trematodes from Reptiles, from material received from the 

 Society's Prosectorium. The specimens were interesting as 

 forming an important addition to our knowledge of the large 

 variety of forms which inhabited the air-passages and anterior 

 coil of the alimentary canal of reptiles and batrachians. 



Dr. R. T. Leiper, M.B., F.Z.S., read a paper on some Parasitic 

 Nematodes from Tropical Africa, and gave a brief description of 

 a number of new genera. The paper was based on helminthic 

 material he had collected during a visit to East Africa, Uganda, 

 and the Soudan in 1907, and on material sent to him by members 

 of the Colonial Medical Service. 



Mr. Oldfield Thomas, F.R.S., F.Z.S., read a paper, the 

 fourteenth of the series, on Mammals collected in Southern 

 Shen-si, Central China, by Mr. Malcolm Anderson, for the Duke 

 of Bedford's Exploration of Eastern Asia. The region explored 

 was in the Great Pe-ling (or Tsin-ling) range, that divides 

 Northern from Southern China, many of the specimens coming 

 from the sacred mountain Tai-pei-san, where several of the most 

 interesting forms were obtained.
