to this, the two names should be interchanged. This does not, how- 
ever, seem to me desirable or necessary. On the board, which 
carries the name Ophiura cylindrica, two specimens have been 
mounted. Only one of these is left. I cannot help suggesting that 
the two specimens may have been one of each of the two species 
here mentioned, because of a discrepancy in Hutton’s description. 
The colour given by Hutton decidedly agrees far better with the 
form here mentioned as P. cylindrica than with P, gracilis; on the 
other hånd, the shape of the dorsal plates — “convex on the outer 
edge, and tapering inwards, nearly as long as broad“ is in con- 
formity with P. gracilis, not with the P. cylindrica of Farquhar 
and later authors. — In view of these facts, and as nothing at 
all is gained by the changing of the names, only a considerable 
confusion certain to arise from this change, I think it the best 
course to keep the name Pectinura cylindrica (Hutton) for the spec¬ 
ies figured and described under this name by Farquhar.

Of this large and magnificent species several specimens were 
taken in Queen Charlotte Sound, 3—10 fathoms, 19/1.1915. 
Further a few specimens were dredged in Paterson Inlet and 
in Halfmoon Bay, Stewart Island in 5—15 fms, in November 1914. 
One of the specimens from Queen Charlotte Sound is 4-rayed. 
— In the only young specimen in hånd (9 mm diameter of disk) 
the grooves between the First and the second ventral plate are not 
to be observed; in the larger specimens they are always distinet, 
though their entrance may be reduced to a mere narrow slit. 
I find the eggs of this species fairly large and yolky, which 
would appear to indicate that its larva does not assume the typical 
Pluteus-shape.
