Nematorrhyncha. After a renewed examination of Chcetonotus [one of 
the Gastrotricha, Zool. Rec. xii. p. 520 : the hemaphroditism is denied, 
and a nervous system shown to exist], Biitschli (25) discusses the sys- 
tematical position of this ambiguous tribe, which, uniting it with the 
sub-order Atricha (viz., Echinoderes), he elevates into a distinct order, 
Nematorrhyncha, the relations of which to other segmented or unseg- 
mented worms and to the Arthropoda are treated in detail. In the 
genealogical tree appended, they are placed between the Nematoda and 
the Arthropoda, the latter forming with the Rotatoria one principal 
branch, the Annulata and Plathelmintha constituting the other. 
VIII. ACANTHOCEPHALA. 
Of Leuckart’s “ Menschlichen Parasiten (3) a large portion 
(pp. 725-871), illustrated with woodcuts, is devoted to the anatomy, evo- 
lution, metamorphoses, and migrations of Echinorrhynchus proteus and 
angustatus (Zool. Rec. x. pp. 492 & 493), though the only instance of the 
(probably accidental) occurrence of an Echinorrhynch in man is the E. 
hominis of Lambl; it has only been found once, and can neither be 
referred to E. gigas nor to any other known species. 
New species : Echinorrhynchus lanceolatus, sp. n., Linstow (4), p. 2, 
pi. i. fig. 3 (intestine of Charadrius hiaticula).
