Angle of diver- gence about 130°. Habitat.—Transvaal Museum (No. 759) is labelled Jeffrey's Bay, St. Francis Bay ; the Museum (No. 250605) is from Port Alfred, and was collected by Turton. The example figured by Pilsbry as carpenteri came from Port Elizabeth ; Sykes' example came from Isipingo. In conclusion.—The name Spongiochiton was proposed in MS. only by Carpenter, listed by Dall in 1873, and published with Carpenter's MS. definition by Pilsbry in 1892 under the Ischnochitoninae. In 1893 Pilsbry published a figure under the name Acanthochites carpenteri, pointing out that it belonged to Dall's subgenus Macan- drellus, a name that Ashby has shown must be replaced by Loboplax Pilsbry. These genera cannot seemingly be valued higher than subgenera, and in face of the very limited material I prefer to attach the generic name Notoplax only. I would point out that N. productus has characters in common with some New Zealand Chitons for which I proposed the subgeneric name Amblyplax, and some allied forms have by some writers been placed with doubtful justification under the genus Craspedochiton. If on further study these groups are found to be con-subgeneric, the name Spongiochiton would antedate the others. Subfamily cryptoplacinae Thiele. Cryptoplax sykesi Thiele.
