I should think the New Zealand Peripatus is not widely different 
in this respect from ours. 
I have examined females of the common Peripatus of New 
Wales at intervals during the greater part of the year. There 
are still a few important blanks in my series when certain details 
are wanted, which I hope soon to be able to fill. I shall, there- 
fore, postpone a full consideration. But I have seen enough to 
show the general trend of matters. 
Of the first lot of specimens I ever had, one specimen was kept 
from June 16th to the last week in October : a few days before 
her death she produced four young ones. In July an embryo 
which had about half completed its development was removed 
from another female of the same batch, and preserved by 
Professor Haswell. I still have this specimen. 
In 1892 I had specimens under observation from April until 
the following March; the first young one was noted on November 
11th. 
In 1893 I got a fine series in the last week of July. A single 
unusually early young one was noticed on August 15th. A few 
others were noticed on September 22nd. By November the 
females were breeding freely, sixty young ones being noted on 
November 22nd. From 15th-18th of August seventeen females 
of this batch in process of being drowned extruded 83 young 
embryos (from 1-14 each) : these vary slightly in age, and com- 
prise specimens at about the same stage, and also at a little more 
advanced stage, than the New Zealand embryo figured by Miss 
Sheldon (Studies, Vol. iv. PI. xxvi. figs. 25-26) ; that is to say, 
the longitudinal ridge along each side of the body from which the 
appendages take their origin, shows rudiments of from about half 
a dozen pairs to nearly the full number. During the following 
week three females were opened; they contained 23, 30 and 37 
very similar stages, together with younger ones and a few ova. 
In the first week in October five females of the same lot when 
being drowned extruded eight embryos; these are much more 
advanced than those extruded six weeks earlier, the full number 
of claw-bearing legs being present. The following week two
