"... ... The structure of the female appendages is beautifully adapted to a remarkable habit in the manner of depositing the eggs, which seems not to have been noticed before among . The eggs are deposited in old logs, in the undersides of boards, or in any soft wood lying among the grass which these s inhabit. By the means of the anal appendages the female excavates in the wood a smooth round hole about an eighth of an in diameter. This hole is almost perpendicular at first but is turned rapidly off in the direction of the , and runs nearly parallel with and about three-eighths of an inch from the surface; the whole length of the hole being an inch or an inch and a fourth. A single hole noticed in the end of a log was straight. The eggs, which are about a fourth of an inch in length, quite slender and light brownish yellow, are placed in two rows, one on each side, and inclined so that, beginning at the end of the hole, each egg overlies the next in the same row by about half an inch. The aperture is closed by a little disk of a hard gummy substance."

"P Smith ... ... the dredgings have very greatly extended the bathymetrical range of this species. It had previously been taken in 250 to 640 s. This increased range in depth is apparently accompanied by a change in the kind of carcinœcia inhabited. All the earlier specimens, over four hundred in number, were found in carcinœcia of Epizoanthus paguriphilus Verrill, while the deep-water specimens were either in a very different species of ', in naked shells, or in an n closely resembling, if not identical with, Urticina consors Verrill, which often serves for the carcinœcium of the next species.

"Although Professor Smith's systematic work on the freshwater and marine entitles him to a position in the front rank of American systematic zoologists, his studies on the life histories of the crustaceae proved of more general interest. He was the first to interpret correctly the successive stages in the larval life of the (1872, 1873); and his descriptions of the early life of other crustaceans, particulary of (1873), (1877), Pinnixa (1880), and (1883), have found a wide application in interpretation of the relationships of the various groups. For several years prior to 1874 he assisted Professor Verrill in the preparation of the classic "Report on the Invertebrate Animals of Vineyard Sound"; an ecological study that had no parallel in America for more than forty years. Professor Smith prepared all the material relating to the crustaceae and revised other parts of this widely used book."
