1258 The Zoologist— June, 1806. 



Gardens. Dr. Giinlher doubted whether this was really a salmon, and was inclined 

 to refer it either to some species of lake trout, or to a hybrid between two different 

 species of Salmo. It appeared that this fish had been hatched from Rhine ova, 

 obtained and deposited in the Society's Gardens by Mr. Buckland, in January, 1863; 

 nevertheless, it did not seem clearly established that the ova were really the ova of 

 Salmo salar. Mr. Buckland made some interesting remarks on the subject, giving a 

 history of the ova, and exhibiting a number of fish which he had reared. A lively 

 discussion followed, in which Dr. Giinther, Dr. Murie and Mr. Buckland were the 

 principal speakers. 



The Chairman exhibited four new species of birds from different pails of the world, 

 and communicated descriptions of'them. One of the most interesting was a grebe 

 from Lake Titicaca, in Bolivia: the wings were remarkably small, so much so as to 

 induce the belief that the bird must be incapable of flight: on this account Mr. Gould 

 proposed to name it Podiceps micropterus. 



April 23, 1868.— W. H. Flower, F.R.S., in the chair. 



The minutes of the last Meeting having been read and confirmed, 



The Secretary read a letter from Mr. LayarJ, of Cape Town, in which he described 

 a new species of ribbon fish (Gymnelrus) lately captured by him. 



Dr. Murie, who had carefully dissected the sea bear (Olaria), which died a short 

 time since in the Society's Gardens, read an elaborate report on its anatomy, and 

 made some interesting remarks on its habits as compared with the habits of other 

 seals. 



The Secretary read a letter from Mr. Geoffrey Nevill, with reference to some new 

 species of Mollusca from the Seychelles aud Mauritius. 



The Secretary also read a communication from Mr. Spence Bate, F.R.S., 

 illustrated by water-colour drawings, on a new genus of fresh-water prawns. It 

 appeared that four closely allied species are knowu from widely separated localities: 

 three of them had been found respectively at Formosa, Patna, and Guatemala; the 

 locality whence the fourth had been obtained was uncertain. Mr. O. Salvin exhibited 

 a specimen which he had procured in Guatemala, where he staled this crustacean was 

 well known as an article of food. Au interesting discussion followed on the singular 

 distribution of this genus. 



Mr. St. George Mivart read an extract from a letter which he had received from 

 Professor Lessona, of Turin, touching the habits and affinities of Salamandrina 

 perspicellata. 



Dr. Gray made some remarks on a new species of marmoset monkey lately placed 

 in the Society's Menagerie, and proposed to name it Mico sericeus. — J. E. 11.
