The first, second and last pereiopods are shown in Text-fig. ie,k and /, as well as the setae on the distal three joints of the first pereiopod. Each pereiopod bears, on the margins of the distal half, a series of small rounded tooth-like projections. The modifications of the first and second pleopods of the male and the form of the penis are very similar to those described and figured by Hale (1946, p. 169 and fig. 4, p. 170) for A. tribulis. The penis (Text-fig. 186) is single but distally cleft. The basipodite of the first pleopod (Text-fig. \a) is about twice as long as broad and has a pronounced curve inwards towards the middle of its outer margin; it bears seven coupling setae on its inner margin (five in A. tribulis) and ten very small teeth on its outer margin (these are also present in A. tribulis). The form of the exopodite is also very similar in the two species, the oblique furrow terminates in a narrow projection, which is bent
