phalen des Hechtes erzogenen Both riocephalen als klei- 

 nere Exemplare von Botjiriocephalus latus Brems, ansehen. 



Der so lange gesuchte und in allen möglichen Wasserthieren 

 oder selbst anderwärts vermuthete Zwischen wir th ist im Hecht 

 und in Loia vulgaris gegeben. 



Mit diesem Resultat haben meine Untersuchungen, die mich über 

 ein Jahr, wenn auch nicht ununterbrochen beschäftigten, einen vor- 

 läufigen Abschluss erfahren ; in einer zweiten Versuchsreihe soll vor 

 Allem die Infection der Zwischenwirthe mit flimmernden Embryonen 

 und die Umwandlungen dieser zu den finnenartigen Jugendzuständen 

 des Bothriocephalus latus ins Auge gefasst werden, wobei auch andere 

 Arten, die mir hier zur Hand sind, berücksichtigt werden sollen, wenn 

 mir die nöthige Zeit bleibt; auch dürfte es nothwendig sein, die Ver- 

 suche der ersten Reihe (Infection mit Hechtbothriocephalen) auf den 

 Menschen auszudehnen ; über die bis jetzt angestellten Versuche hoffe 

 ich bald ausführlicher berichten zu können.

2 Ith February, 1882. — The Secretary read a Keport on the additions 

 that had been made to the Society's Menagerie during the month of January, 

 1882, and called special attention to a young male Gayal, born in the Gar- 

 dens, January 6, being the produce of the fine pair received in exchange, in 

 October 1880, from the Zoological Gardens, Calcutta; and to a young fe- 

 male Markhoor [Capra mcgaceros) from Afghanistan , presented by Lieut. - 

 Col. Oliver B. C. St. John, F.Z.S. — Mr. F. Moore read a paper con- 

 taining an account of the Lepidoptera collected by the Rev. J. H. Hocking, 

 chiefly in the Kangra District, N.W. Himalaya, with descriptions of new 

 genera and species. — A communication was read from Mr. G. A. Bou- 

 lenger, C.M.Z.S., in which he gave the description of a Frog [Phyllomedusa 

 hypochondrialis) lately living in the Society's Gardens. This Frog had been 

 obtained at Fernambuco, and was believed to be the first example of the 

 species that had reached Europe alive. Attention was drawn to the peculiar 

 coloration, as being worthy of notice, it not having been described before. 

 — Mr. Oldfield Thomas read a paper containing the descriptions of a small 

 collection of Rodents which had been obtained by the late Mr. C. J. An- 

 dersson in Damara Land and in the neighbouring countries. The collection 

 contained examples of a new species of Mouse, which was projiosed to be 

 named Mus nigricauda. — Mr. W. A. Forbes gave a description of the 

 pterylosis of Mesites, and made some remarks on the position of that genus, 

 which he considered to be most nearly allied to Rhinochetus and Eurypyga, 

 though all these three forms should be referred to difierent families. — Prof. 

 St. George Mivart read a series of notes on the anatomy of the Canada 

 Porcupine [Erithizon dorsatus) . — P. L. S dater, Secretary.
