DISTRIBUTION. — Western Pacific Ocean: Japan (see Sakai 1976, as P. stridulans ), Taiwan ( Hsueh & Huang 2002, as P. stridulans ), Vietnam ( Zarenkov 1972, as P. stridulans ), and the Philippine Is ( Guinot 1990). Depth: 190- 521 m. Sakai (1976) reports it (as P. stridulans ), from depths of 75-150 m and Zarenkov (1972: 231) lists it (as P. stridulans ) at a questionable depth of 925 m. Specimens were also obtained from tangle nets of local fishermen in the Philippines that obtained material from at least an estimated depth of 50 m.

REMARKS

Diagnostic of P.musicus are smooth, unarmed P3-P5 carpi and propodi as observed with the naked eye. In most specimens the outer orbital teeth are triangular, foliaceous, and straight, and the anterolateral teeth are relatively short and triangular, not conspicuously slender ( Guinot 1990: figs 35, 37, 38). The shape and relative size of the outer orbital and anterolateral teeth, however, may vary as in other species of Psopheticus . Two of the characters used by Guinot (1990) to separate P. musicus from P.crosnieri , which is known only from Madagascar and la Réunion (outer orbital tooth that is oriented outwardly, anterolateral tooth that is slender, or spiniform, in P. crosnieri ) were observed in a few of the specimens collected in Bohol, Philippine Is.
