and showed that they belong to a different species, which Mr. Sharpe 
proposed to call Coccothraustes Humii. 
Mr. F. EK. Beddard read the third of his series of notes on the Isopoda 
collected during the voyage of H.M.S. ‘Challenger.’ The present paper 
completed the preliminary description of the new species of this group 
collected during the voyage, which amounted altogether to about forty-five 
in number. 
Mr. J. H. Leech exhibited and described specimens of a Butterfly from 
Mogador, which he referred to a variety of Anthocharis eupheno. 
February 16, 1886.—Dr. St. GroreE Mivart, F.B.S., Vice-President,

The Secretary read a report on the additions that had been made to the 
Society’s Menagerie during the month of January, and called attention to a 
many-marked Snake, Ehagerrhis multimaculata, presented by the Rev. 
G. H. R. Fisk, and received January Ist, 1886; also to the birth of eight 
Tree Snakes, in the Society’s Reptile House, on the 9th January. The 
mother, a fine example of Dryophis prasina, presented by Dr. F. H. Bauer, 
of Buitenzorg, Java, was received on the 15th August last, so that she must 
have been for upwards of five months withunt any possibility of intercourse 
with a male of the same species. 
Mr. Sclater exhibited a specimen of the new Paradise Bird, Paradisornis 
Rudolphi, of Finsch and Meyer, lately discovered by Mr. Hunstein in the 
Owen Stanley Mountains ol New Guinea, and pointed out the characters in 
which it differs from typical Paradisea. 
The Secretary exhibited, on behalf of Mr. L. Taczanowski, the skin of 
an Owl from the south-east of the Ussuri country, on the frontiers of Corea, 
which appeared to be referable to Bubo Blakistoni of Seebohm. 
Mr. E. Gerrard, jun., exhibited heads and skulls of two African Rhino- 
ceroses, fi, bicornis and Rh. simus, obtained by Mr. Selous in Mashuna-land. 
Prof. Ray Lancaster exhibited and made remarks on a drawing of a 
restoration of Archaeopteryx. 
Mr. Oldfield Thomas gave an account of a striking instance of cranial 
variation due to age, as shown in two specimens of the skull of the Canadian 
Marten, Mustela Pennanti, which presented extreme differences in the 
breadth of the zygomata, in the contraction of the interorbital space, and in 
the development of the occipital crest. Special stress was laid on the fact 
that such changes as these take place after the animal has attained maturity. 
Mr. W. L. Sclater exhibited and described a new Madreporian Coral, 
which he proposed to call Stephanotrochus Mosleyanus. The coral had been 
dredged in the Faroe Channel during the cruise of H.M.S. ‘Triton’ in the 
summer of 1882. Some account of its anatomy and histology was also 
given.—P. P, Scrater, Secretary.
