346 THE ZOOLOGIST. 
A communication was read from Mr. A. H. Garrod, on the brain and 
on other points in the structure of the adult male Hippopotamus, which 
was presented to the Society by the late Viceroy of Egypt in 1850, and 
which died in the Society’s Gardens in March, 1878. 
A second communication from Mr. Garrod contained a note on the 
mechanism of respiration, as well as of the retraction of the head and limbs 
in certain Chelonia. 
Dr. Gwyn Jeffreys communicated the second part of his work on the 
Mollusea of the ‘ Lightning’ and ‘ Porcupine’ Expeditions, embracing 
the families from Anomiide to Arcide. The number of species noticed 
was 100, of which four were new to science, and fifteen were hitherto 
unfigured. Particulars were given of the geographical and geological 
distribution of all the species, and their synonymy was discussed. Some 
species of Leda and Malletia were Sicilian fossils of the pliocene formation, 
aud had not been previously known as recent or living. These species 
occurred at great depths, a fact which showed that the sea-bed in that 
part of the Mediterranean had been considerably raised since the tertiary 
epoch. 
Mr. Edward R. Alston read a note on the Acanthomys leucopus of 
Gray, showing that it does not belong to the genus Acanthomys, but to 
Mus proper. As the name leucopus is pre-occupied in the latter genus, he 
proposed to call the species Mus terra-regina. 
Mr. W. L. Distant read a paper on the African species of Lepidoptera 
of the genus Papilio. A new species from Magila, East Africa, was 
described, and the name of Papilio Hornimani was proposed for it. 
A communication was read from the Count T. Salvadori, containing 
further particulars of the new Pheasant from Western Sumatra which he 
had recently described as Acomus inornatus. 
Messrs. Godman and Salvin gave an account of some _ hitherto 
unrecorded diurnal Lepidoptera, obtained by the Rev. George Brown in 
Duke of York Island and New Ireland, together with descriptions of some 
apparently new species. 
A communication was read from Mr. F. Jeffrey Bell, being the 
second of the series of his observations on the characters of Echinoidea. 
The present paper contained an account of the species of the genus 
Tripneustes. 
Messrs. Sclater and Salvin read a paper on the birds of Bolivia, based 
principally upon an examination of the specimens obtained by Mr. Buckley 
during two expeditions into that country. 
This Meeting closes the present Session. There will be no more 
Scientific Meetings until the commencement of the next Sessson, 1879-80, 
in November next.—P. 8. Sonarer, Secretary.
