Amœba lescheri (= Chaos lescheri): a New Species of Amœba


EARLY in 1938 I discovered a new species of Chaos (better known as Amœba in Great Britain) which I propose to name Chaos lescheri = Amœba lescheri, to honour the memory of Mary Adela Lescher, founder of Notre Dame College, Glasgow. A full account of the life-history of this amœba will appear in the Quarterly Journal of Microscopical Science. The amœbæ of the genus Chaos are large and form pseudo-podia that are sub-cylindrical, blunt and filled with granular endoplasm throughout. Conspicuous longitudinal ridges and grooves are characteristic of the ectoplasm. Amœba lescheri is readily distinguished from the other species of Chaos by its crystals, which are square prisms (maximum size 2 μ). Outsized spherical individuals attain a diameter of 525 μ, creeping individuals a length of 600 μ. The average for the former is 350 μ and for the latter 400–500 μ.
