BRITISH LOCALITIES:—

England: Clifton, banks of the Avon; (W.M.W. from J.T.C., 1900): Shirehampton, near Bristol; (Stebbing in 49): Clifton; (Dollfus from Miers 14).

FOREIGN DISTRIBUTION:—

Europe: France; Italy; (25): Asia Minor; (14, quoting Brandt).

Distribution of Species. There are not sufficient records at present to enable us to draw any conclusions as to the general distribution of Woodlice in the British Isles, but it is hoped that more attention will be given to these creatures, and that before long there may be other material available.

Conclusion. At the beginning it was mentioned that the present work grew out of an investigation into the fauna of Essex, and in order to show what may be expected when places are explored in which no collecting has been done, we may briefly indicate the results which we obtained in the county in question.

It was not long before a species new to Britain—to wit, Porcellio ratzeburgii—was found (74). This discovery was mentioned by Mr. Stebbing in the Victoria County History of Essex (p. 71), and he prophesied that most of the British species then would be met with in the county. We may safely claim to have shown that his prediction was true, for we have been able to record in the preceding pages no less than sixteen other species, as will be seen from the following lists:—

WOODLICE RECORDED FROM ESSEX.

1.Ligia oceanica10.Porcellio pictus
2.Ligidium hypnorum11.Porcellio dilatatus
3.Trichoniscus pusillus12.Porcellio laevis
4.Trichoniscus roseus13.Porcellio ratzeburgii
5.Haplophthalmus danicus14.Metoponorthus pruinosus
6.Oniscus asellus15.Cylisticus convexus
7.Philoscia muscorum16.Armadillidium nasatum
8.Platyarthrus hoffmannseggii17.Armadillidium vulgare
9.Porcellio scaber

Of these Ligidium hypnorum calls for special mention, as it had not been found in this country since Mr. Stebbing discovered it in Surrey in 1873. Several of the Porcellios and Cylisticus convexus have been met with in but few places, and the same may be said of Armadillidium nasatum.
