 the Gulf of Oman. The southern limit of the range has not been determined, the 

 records from Zanzibar and Dar-es-Salaam being based on doubtfully correct deter-

 by the dredge as it was swimming at or near the surface. 



History. — This species was first mentioned by Prof. Friedrich Sigismuml
