einziges Mal, als ich die Thiere bei ihrer Begattung oder Umarmung 

 beobachtete, vom Weibchen aufgenommen. Das eine Mal blieb der 

 Spermatophor an der Cloakenwandung des Weibchens hängen, das 

 andere Mal haftete er an seinen hinteren Extremitäten. Im Verlaufe 

 von 2Y2 Stunden habe ich vier Emissionen des Samens beobachten 

 können, welche etwa alle 30 bis 50 Minuten stattgefunden haben. Der 

 zuckenden Bewegungen am starr daliegenden Männchen, welche die 

 Vorboten der jedesmaligen Emission sind, habe ich je 90 bis 100 ge- 

 zählt. Sämmtliche Spermatophoren gingen, wie gesagt, verloren, das 

 Weibchen nahm sie weder auf, noch hat es seinen Laich abgesetzt.

2nd May 1882. Before commencing the usual proceedings, the President 

 called attention to the fact that one of the communications made to the pre- 

 vious Meeting was from the pen of Charles Darwin ; and took the opportunity 

 of referring to the labours and character of the illustrious naturalist, whose 

 work had so profoundly modified not only zoological science, but so many 

 other departments of human thought. — Mr. S dater exhibited a drawing 

 of a Tapir presented to the Society by Mr. Fritz Zürcher in August last, 

 which had been captured on the Yuruari River in Venezuela. Mr. Sclater 

 observed that in form and colour this animal seemed to agree better with 

 Tapirus Dowii than with the ordinary T. americanus, and suggested that it was 

 quite likely that the former species might be the Tapir of the northern coast- 

 region of Columbia and Venezuela. — Mr. J.E.Harting, F.Z.S., made 

 some remarks on the desirability of adopting a standard of nomenclature 

 when describing the colours of natural objects. — Dr. Hans Gadow, 

 C.M.Z.S., read a paper on the structure of feathers in relation to their co- 

 lour, in the course of which he endeavoured to show how the optical appea- 

 rances of the various colours met with in the feathers of birds were pro- 

 duced. — Prof. Flower, F.R.S., gave an account of the cranium of a 

 Cetacean of the genus Hyperoodon from the Australian Seas, upon which he 

 proposed to found a new species, H. latifrons. — A communication was 

 read from Dr. O. Staudinger containing the description of some new and 

 interesting species of Rhopalocera from the New World. — A communica- 

 tion was read from Mr. H. J.Elwes, F.Z.S., containing a description of 

 a collection of Butterflies made on the Tibetan side of the frontier of 

 Sikkim, amongst which where examples of several species new to science. — 

 A communication was read from Mr. Edgar L. Layard, F.Z.S., describ- 

 ing a new species of Parrot of the genus Nymphicus from Uvea, one of the 

 Loyalty group, which he proposed to call Nymphicus xivaeensis — P. L. S da-
