Peripatus. 
Of the various positions given to this form, that suggested by Gegen- 
baur (Grundriss Anat., 2nd ed. 1877) is probably the most satisfactory ; he 
regards them as Protracheata, a group of Arthropoda equivalent to the 
Branchiata on the one hand, and the Tracheata on the other. 
Hutton’s statements (Ann. N. H. 4, xviii. pp. 361-369, pi. xvii.) 
[1876] were made with an incomplete knowledge of Moseley’s original 
paper ; he notes the ejection of viscid fluid for purposes of offence, and 
believes he has evidence of moulting, and that breeding occurs all the 
year round. His observation of hermaphroditism is declared by Moseley 
(Ann. N. H. 4, xix. pp. 85-91) to be due to a misapprehension ; in answer 
to which Hutton (op. cit. xx. pp. 81-83) re-affirms the existence of herma- 
phrodite, though allowing the existence of male, forms.
