Caryopbyllw sewe/li was described by GARDI ER & WAUGH (1938) from the southern Red Sea from<br />

a depth of 366 m (Stat. 209). ZI BROWI US (1974) states that a specimen in Senckenberg Museum (No. 521 ),<br />

collected by the "Valdivia" near St. Paul in the southern Indian Ocean, which he describes under Caryopbyllw<br />

sp., has great resemblance to C. sewelli. He su pposes that his specimen belongs to a suite of the<br />

same " Valdivia" station, which MAR ENZELLER ( 1904) has published as C. arcuata.<br />
