Plate XXIV. 1799 Oniscus pulchellus Zencker (78) (quoted by Koch in Panzeri, part 62, pl. XXI. 1833 Armadillidium pulchellum Brandt (3), p. 188. 1861 Armadillo maculatus Sill (60), p. 5. 1870 Armadillidium pictum Plateau (not Brandt) (55), p. 116. 1898 Armadillidium pulchellum Sars (59), p. 191, pl. LXXXIII., fig. 4. The smallest British species is Armadillidium pulchellum. The frontal lobe projects so as to make the head somewhat triangular. The antennae are very short and the distal joint of the flagellum is three times the length of the other, while the two together are not as long as the last peduncular joint. The telson is truncated at the end so that it is by no means as long as it is broad at the base, and the outer divisions of the tail appen- dages are in similar proportion. The colour of the body (which is smooth) is dark brown with four important series of light patches running down the back and less marked variegations between them.
