* Furcula is the name used by Tullberg for the ventral spring, the basal segment is the rnanubrium, the middle segment the dentes, and the apical segment the mucrones.

† Schott describes the following new species from California, and adds several European species:—Entomobrya nivalis, Linn, p. 16. E. multifasciata, Tullb. = D. decemfasciata, Pack, p. 17. E. marginata, Tullb, p. 17. Sira purpurea, Schott, p. 17. Drepanura californica, Schott, p. 19. Orchesella rufescens, Lub., p. 21.

* Tullberg erected this genus for the reception of a species from Nova Zembla, C. borealis, Tullb. The characters separating it from Isotoma are certainly superficial.

† As the description of this genus may be inaccessible to many, it is appended: “Mesonotum non prominens. Segmentum abdominale quartum triplo vel quadruplo longius quam tertium. Antennæ dimidia parte corporis breviores, quadriarticulatæ, articulo secundo et tertio inter se fere aequalibus, quarto omnium longissimo. Ocelli 16; 8 in utroque latere capitis. Pili clavati praecipue in regione cervicis et in segmentis apicalibus stipati. Mucrones furculae parvi falciformes. Squamæ? Type, Drepanura californica, Schott.

* Derived from the name of a village.

† στρογγύλος, rotundus: νωτος, dorsum.

* Schott adds the following:—Smynthurus eisenii, Schott, p. 7. S. luteus, Lub., p. 11. S, niger. Lub., p. 12. S. plicatus, Schott, p. 13.

* Schott adds a single species, Papirius maculosus, Schott, p. 14.
