once mentioned b)' Mr. T. Ni.sliik;uva'\ He collected, in early February 
1898, many eggs of the Abraliopsis of an earlier Ljnbryological stage "' — 
Nepioteuihion stage of Compsoteutkis Nishikazvae of Pfeffer's "'' — at Aburatsubo 
Bay, Misaki. And again, be obtained, in April, 1900, like the above, as well 
as some developed larvae { CompsoteiUJiis Nisliikaivae Pfeffer) — Coinpso- 
teutlits stage of Chun's'"'' — at Enoura, Suruga Province. But, judging by 
the maturation of the specimens from Awa Province and Sagami Bay mention- 
ed before (sec p. 89), as they should be mated there in March at the earliest, 
the first kind of Nishikavya's egg seems to have been collected too early to 
identify them with the present species Watasciiia sciiiiiHans, while the second 
kind may be said to be the ConipsotcntJiis stage of the present species for the 
same reason.
