78 THE ZOOLOGIST. 



Could his friend Prince C. L. Bonaparte have been now 

 amongst us, what a tribute would he not have paid to the 

 memory of one whose fame he long ago predicted, when, in 

 that elegant Latin preface to his ' Conspectus Generum Avium,' 

 which he dedicated to Schlegel in 1850, he referred to the bright 

 expectations of a career which have since been so nobly realised.

SCIENTIFIC SOCIETIES. 



LiNNEAN Society of London. 



January 17, 1884. — Sir John Lubbock, Bart., M.P., F.R.S., President, 

 in the chair. 



Mr. A. Penniugton was elected a Fellow of the Society. 



A presumed portrait, in oil, of LiuuEeus was exhibited on behalf of 

 Mr. F. Piercy. 



A paper was read by Mr. A. D. Michael, " On the ' Hypopus' question, 

 or life-history of certain Acariiia." From a careful series of experiments 

 and observations he concludes that true Hypopi are not adult animals, 

 but only a stage, or heteromorphous nymphs, of Tyroglyplius and allied 

 genera. Nor do all individuals become Hypopi, which latter stage takes 

 place during the second nymphal ecdysis. It seems a provision of nature 

 for the distribution of the species irrespective of adverse conditions. 

 Hypopi are not truly parasitic, nor confine themselves to any particular 

 insect. A new adult form described is called by the author Disparipes 

 homhi, and he believes there are other species of the genus Donnadieus, 

 bee-parasites admitted to be adults, though it is uncertain if they are 

 identical with Dufour's Trichoclactylus. The following specimens were 

 exhibited under the microscope in illustration of the paper: — Disparipes 

 homhi, inert fully grown nymph, showing the adult female fully formed 

 inside ; also male, female, and latter from under side, of the new species 

 D. homhi. — J. MuRiE.
