Taxonomy: Chen and Sun (2002: as Philyra View in CoL ), Galil (2009). Type: Holotype ò NHM 1847.21 ( Galil 2009). Type locality: Borneo. Distribution: South China Sea and coasts of China: Borneo, coasts of China and Korea ( Galil 2009). Habitat: Intertidal to shallow subtidal; on sandy or muddy substrates.

Remarks: Pyrhila carinata and P. pisum can be readily distinguished from each other based on a conspicuous granulated ridge along the median line ( P. carinata ), or patch of beaded tubercles around the cardiac region ( P. pisum ) ( Galil 2009). Stimpson’s (1858c) “ P. tuberculosa ”, following his illustrations in 1907, is considered to represent P. carinata instead ( Galil 2009).
