Remarks. — The Ifaluk specimens agree with the typical form of 

 this well-known and widely distributed species. It has not been 

 described in detail here. The geographical distribution has been 

 summarized by Sewell (1940, p. 314) and discussed at some length 

 by Lang (1948, p. 1348). The following additional records may 

 be mentioned here: the Dalkey area of County Dublin and Lough 

 Ine of County Cork, Ireland (Roe, 1958, 1960); the Plymouth area 

 of England (Marine Biological Association, 1931, 1958; Fraser, 1936); 

 the Whitstable area of County Kent, England (Maghraby and Perkins, 

 1956); the Bay of Santos in Brazil (Carvalho, 1952); the Rovinj, 

 Yugoslavia, area in the Adriatic (Vatova, 1928); Addu AtoU in the
