SECTION IV.--PART I.--ACANTHOCEPHALA (Thornheaded worms). _Echinorhynchus gigas_, Goeze.--There is but one recorded instance of the occurrence of this entozoon in the human body. This is the oft-quoted case by Lambl, given in the ‘Prager Vierteljahrschrift’ for 1859. Lambl, indeed, described it as a separate species (_E. hominis_), but as the worm was a sexually-immature female, its identification with _E. gigas_, notwithstanding Schneider’s great authority, can hardly be regarded as absolutely certain. The worm was found in the small intestine of a boy of nine years, and measured only rather more than the fifth of an inch in length. As Leuckart hints, the worm may be _Echinorhynchus angustatus_, or possibly the _E. spirula_, a species found in various South American apes (_Cebus_ and _Jacchus_), and also in the Barbary ape (_Inuus_).
