SYSTEMATIC DESCRIPTION. 
SupER-OrRDER OSTRACODA. 
Section PODOCOPA. 
Famity CYPRIDA. 
Genus PHLYCTENOPHORA G. S. Brady. 
PHLYCTENOPHORA ZEALANDICA GC. S. Brady. 
Phlyctenophora zealandica G. 8. Brady, 1880, Rep. Chall. Zool. vol. I, pt. II, 
p- 33, pl. III, figs. la-m. 
Observations.—It is curious to find a single valve of this species in so great a 
depth as 1,300 fathoms. It has hitherto been taken either in the tow-net or in shallow 
water. The present example shows the characteristic blotches in the colouring of the 
valve. 
Previously recorded from Wellington Harbour, New Zealand; Sydney Harbour; 
and Humboldt Bay, Papua. 
Occurrence.—No. 56 (11th December, 1912), 675 fathoms. No. 60 (12th December, 
1912), 1,300 fathoms.

pl. XXX, figs. 6a-d. 
Observations —This neat little species is represented by several separate valves 
in the present series, some of which vary in being more elongate. 
The species was formerly known from the dredging off Hast Moncceur Island, 
Bass Strait, 38-40 fathoms. 
Occurrence.—No. 29 (14th February, 1912), 125 fathoms. No. 60 (12th December, 
1912), 1,300 fathoms. No. 139 (27th January, 1914), 328 fathoms (figured. species) 
slender variety.

Observations.—The present occurrences are remarkable for their great depths, 
all previous records being from shallow water, with the exception of Funafuti (200 
fathoms), and East of Tasmania (700 fathoms). Those now recorded are of typical form,
