PROCEEDINGS OF SCIENTIFIC SOCIETIES. 
Linnean Socivty or Lonpon. 
May 6, 1880.—H. T. Srainvon, F.R.S., in the chair. 
Three Foreign Members were elected, viz., two distinguished botanists, 
M. ©. J. de Maximowicz, Director of the Imperial Botanic Gardens, 
St. Petersburg, and Prof. E. Strasburger, of the University of Jena; and 
one zoologist, Prof. Elias Metschuikoff, the indefatigable Director of the 
Zoological Institute of Odessa, and whose researches, both embryological 
and anatomical, among the marine invertebrata hold a high place. 
Prof. P. Martin Duncan orally communicated the substance of a paper 
“On an unusual form of the Genus Hemipholis, Agass.” 'This was dredged 
by Dr. Wallich off the Algulhas Bank, 8.W. of the Cape of Good Hope. 
Its zoological position may be doubtful, for the classification of the 
Ophiurioidea is at present full of anomalies; but the specimen nevertheless 
possesses unusual interest, from the peculiar nature of the so-called dental 
or chewing apparatus. These oral structures and other specialities of 
conformation were elucidated in detail by the author. 
Prof. E. Ray Lankester read a paper “On the Tusks of the Fossil 
Walrus found in the Red Clay of Suffolk.” He now withdraws the generic 
name of Trichecodon instituted by him in 1865, and refers a series of later 
discovered large tusks in the Ipswich Museum, including the former 
specimens, to belong to the living genus Trichechus, but he specifically 
distinguishes this as 7’. Hualeyi. Prof. Lankester, moreover, is inclined 
to think there is very insufficient grounds for the generic subdivisions 
Alachtheriwm and Trichecodon, as used by Prof. Van Beneden, nor is there 
evidence, according to the former, for the association of the Suffolk and 
Antwerp tusks. 
A short communication, “ Ou an irregular Species of Amblypneustes,” by 
Mr. Charles Stewart, was taken as read. 
A letter was read by Mr. Thomas Christy on Mr. Blacklaw’s unsuccessful 
endeavour to raise the Liberian coffee at St. Paulo, Brazil; and a paper on 
Brazilian Algz, by Prof. Dickie, and another, by Mr. T. Bettany, against 
the use of tri- and poly-syllabic terms in botanical nomenclature, were read 
and discussed.—J. Muriz. 
ZooLoGicaL Society oF Lonpon. 
May 4, 1880.—Prof. Fuowrr, LL.D., F.R.S., President, in the chair. 
The Secretary read a report on the additions that had been made to the 
Society’s Menagerie during the month of April, and called special attention
