WOODLICE.

T h e earliest adequate enumeration of indigenous kinds is, probably, Leach's of five species in Brewster's Edinburgh Encycl. 1810, vii, 406. Kirby knew something of aquatic ' Oniscidae ' (Introd. capp. xxii-iii), but little of Woodlice. In 1857-9 Kinahan analysed fourteen British terrestrial Isopoda in the Dublin Nat. Hist. Review, twelve of which had been discovered in a Single garden. By 1868 Bäte and Westwood (ii, p. 438) were able to recognise seventeen kinds of their TEro-spirantia division of Normal Isopoda, i.e. Terrestrial with the upper antennse rudimentary and apical segment of abdomen very small, in contradistinction to the aquatic Aquaspirantia. An elaborate monograph on ' T h e British Woodlice ' with excellent figures was published by W . M. Webb and Charles Sillem in 1905-6 (Essex Nat. xiv ; and also separately by Duckworth & Co), showing at page 54 Britain to contain twenty-five species ; of these Collinge in 1917 (Scot. Nat., p.p. 111-6) issued a Check List. All such and one addition are enumerated below, though only the Suffolk dozen are numbered, consecutively to Trans, ii, 271, and italicised. We are much indebted to Mr. Ernest Taylor, of the Hope Department of Oxford University Museum, for liberal assistance in identification. At least, the extra five kinds that are known in Essex will be found to occur in Suffolk, where but small attention has been hitherto accorded this Family.—Ed.

In this attitude its legs and underside, which are soft, are entirely defended by the hard crust forming its upper surface. Ihese balls are perfectly spherical, shining, black and belted with narrow white bands, so as to resemble beautiful beads; and, if they could be preserved in this form and strung, would maKe very ornamental necklaces. At least so thought Swammerdam s maid (circa 1670) who, finding a number of these Insects thus rolled up in her master's garden and mistaking them for beads employed herseif in stringing them on a thread : when the poor animals began, to her great surprise, to move and struggle tor liberty, she threw down her prize and ran away in the utmosi alarm!
