bryos, which he found on the underside of stones in the Bay of 
Islands, Wellington, to Ophionereis Schayeri (viz. O. fasciata) are, 
that the terminal plate of the young Ophiurids resembles that of 
the said species, and that this species is very common in the 
neighbourhood. 
Grave objections may be raised to the referring of these eggs 
and embryos to Ophionereis fasciata. Above all: the eggs of this 
species are very small, ca. 0,i mm, while the eggs observed by 
Kirk were 0,5 mm. This small size of the eggs in Ophionereis 
fasciata almost certainly indicates that it has typical pelagic larvæ, 
not direct development. Further Kirk States that the tubefeet of 
the young Ophiurids were provided with a number of bristle-like 
processes; but the tubefeet of O. fasciata are perfectly smooth. It 
is, of course, possible that in the quite young newly metamorphosed 
specimens the tubefeet may be provided with such bristle-like pro¬ 
cesses — but it is not very probable. The terminal plate of O. 
fasciata is by no means so characteristic as to afford any proof of 
the identity of the embryos with this species. Finally there are 
other Ophiurids occurring under the stones in the same way and 
the same places as O. fasciata v\z. e. g. Pectinura cylindrica, Ophio- 
plocus Huttoni, Ophiopteris antipodum, Ophiozonoida picta, Ophio- 
cormus notabilis. Any one of these species is more likely to come into 
consideration in the question about the parency of the directly 
developing embryos described by Kirk, in so far as nothing is 
known as yet to prevent their coming into consideration.
