primaries redder, the lines darker and less strongly undulated, 
the central line straight, the fringe less deeply white-tipped ; 
secondaries with much less white on the fringe: wings below 
darker, the lines darker, the discal line of secondaries carried 
across the wing, as in G. combinans. Hxpanse 1 inch 10 
lines. 
Yokohama (Jonas). 
G. fulvida (Anomis fulvida of Guénée) is a native of Java 
and the Andamans; we have also an example labelled 
“ North India.” Walker confounded a larger Indian species 
with it; but the latter is scarcely distinguishable from his own 
Gonitis revocans from Australia.

XXV.—Further Notes on the Structure of Peripatus nove- 
zealandie. By F. W. Hurron, Professor of Zoology in 
the University of Otago. 
Durine the last three months I have dissected several more 
specimens of Peripatus nove-zealandie, with the advantage 
of Mr. Moseley’s paper before me ; and I hasten to communi- 
cate the results, because I wish to correct several errors into 
which I have fallen, and to confirm, as soon as possible, Mr. 
Moseley’s statement of the existence of male individuals. 
Integumentary System.—The last joint of the legs consists 
of a short subcylindrical joint, on the upper and outer margin 
of which are three large papille, and below two large curved 
simple claws. On the fourth and fifth pairs of ambulatory 
legs there is a circular opening in the centre of the inner side 
of the first, or inner, tarsal rimg—that is, on the fifth ring from 
the end. I am, however, doubtful whether the tarsi should 
not be considered four-ringed only. 
Muscular System.—My supposed “salivary bags’ (see 
Ann. & Mag. Nat. Hist. 1876, xviii. p. 364) are the same as 
Mr. Moseley’s “ retractor muscles of the head” (see Phil. 
Trans. vol, 164, pl. xxii. fig. 1,7m). Mr. Moseley is right in 
ealling them muscles ; my mistake arose from believing the 
tracheze on them to be internal instead of external. They are, 
however, the flexor or adductor muscles of the teeth. The 
pairs of teeth are not moved simultaneously. Generally their 
movements are alternate, but often one pair is moved several 
times, while the other is stationary ; there is also a movement 
by which the two teeth of a pair are separated and approxi- 
mated. The two pairs of teeth, when in use, sometimes 
touch each other at the tips; but they never cross.
