But he has made the interesting discovery that in the type species (mihiwaka Chilton) and two other New Zealand species the 1st pleopod in the o* is modified. This fact entirely alters the situation. The species capensis is not a suitable companion with species in which the males have an enlarged gnathopod 2 and a modified 1st pleopod. At Dr. Hurley's suggestion I re-examined the type material of capensis and found there was no modification of the 1st pleopod in $. This fact was com- municated to him. He has suggested the possible desirability of raising the South African and Australian species to subgeneric or generic rank (Hurley, loc. cit., p. 576 and footnote). The Australian species still await detailed investigation, but I have no hesitation in removing capensis to a different genus. The adoption of the prefix Afro- indicates my doubt that the Australian species will be found to be congeneric with the South African. Ruhe's record (1914, D. Siidpol. Exp., xvi, p. 35, figs. 13, 14 a-c) oi'Chiltonia subtenuis Sayce' from Lakeside Vlei is curious and needs further inquiry. He figures an enlarged gnathopod 2 (fig. 13^) but says he had 6 young females measuring 1-5 mm. Lake- side Vlei is the .same as Muizenberg Vlei, from which I have seen material collected by In this material there are no 0*6* with enlarged 2nd gnathopods. Additional localities. Muizenberg Vlei; KosiBay,Zululand; Olifants River mouth. () Another apparent error in Ruhe's paper: he records a Para- moera sp. ? and figures (fig. 14^) the characteristic telson of P. capensis, but gives the locality ' Plums tead', which is some five miles inland from the coast.
