In 1941 E. LELOUP gave (p. 1) the new name Ischnochiton (Lepidozona) berryanus to the species described and figured by BERRY (1917, pp. 10—12, pl. 6 fig. 5—9, pl. 7) as I. (L.) pilsbryanus, because the latter name is preoccupied by I. (Stenochiton) pilsbryanus Bednall, 1896. LELOUP must have overlooked BERRY’s publication of 1918, where the author himself gave a new name to his I. (L.) pilsbryanus, viz. I. (L.) nipponicus. The name I. (L.) berryanus must, therefore, be dropped.
