A small example, 16^ inches in length, from Beirut, Syria, probably 

 belongs to this species. It has — Head 7f ; depth 17; D, about 124; 

 A. LXXX? (and a few obsolete) ; snout 3 in head, from tip of upper 

 jaw; eye oh; interorbital space 7; maxillary 2h; pectoral 3. 



This species is closely related to Trichiurus lepturus Linnaeus, differ-

 T. haumela was recorded a number of times from India,^^ although 

 Day considered his T. malaharicus^ from Cochin as identical.
