It may be that these specimens have not attained their full development, as none of them ap- proach the type in size. Interior blue-green, white towards the edges. Girdle grey-green, leathery, a minute pore at each suture, 4 on anterior valve. The dotted lines on figs. 5 and 7 show the limit of the white granular patch. Figs. 6 and 7 represent the posterior valve of a second specimen. Length of dried specimen. 35 mm.; width, 18 mm. Habitat: Orua Bay, Manukau Harbour, New Zealand; on rocks at low tide. Type in Coll. W. H. Webster. The type is unique; seven of the less-developed speci- mens were found. The apparent hybridism is striking, especially as I have never found A. violaceus on the west coast, though a very small form of A. zelandicus is fairly ; Shortly afterwards Thiele described a shell labelled, in the Paris Museum, Stewart Island, as Loboplax stewartiana, but the description and figures which are here reproduced fit the "mariae" of Webster so com- pletely that it was at once regarded by Iredale and Suter as A. B. Fig. 1. A. Acanthochites (Loboplax) mariae, copy of Webster's figures. B. Loboplax stewartiana, copy of Thiele's figures. On account of the locality, Ashby has used the name subspecifically, but we now suggest that the locality is false and that the Paris Museum shells came from the North Island. This is quite a legitimate suggestion, as prior to Thiele's examination the collection of Loricates in the Paris Museum had been mishandled by Rochebrune, labels and specimens being disarranged and even lost.
