laterals, though still apparently somewhat less freely movable. Inte 
nodes are considerably expanded laterally at back of hydrothecae, ней 
ments so formed taking the place of the more definite peduncles found sup- 
porting the paired sarcothecae in most species. The pairs of sarcothecae 
on rachis are not attached to hydrothecae, but situated a little distance 
above them, and the regular supracalycine pir are wanting. 
Male and female gonangia may be found on s shoot. The former 
are remarkably small, being but little longer i1 бе апа onl 
about half their diameter. They differ from those of most allied species 
in the total absence of sarcothecae. The female gonangis, on the other

faint circular suture at the tops, but no thickened border. One had four 
large sarcothecae round base; on the other I found only two, but possibly 
others had become detached.

Aglaophenia filicula Hilgendorf, 1897, p. 215. 
Hilgendorf refers this form to A. filicula Allman, which is classed by 
Bedot as a synonym of А. tubulifera Hincks. The species is indeter- 
minable ; Hilgendorf’s description would apply equally to many other 
species, and the figures are not sufficient to serve for identification.

Aglaophenia incisa Coughtrey, 1876, p. 31: Farquhar, 1896, p. 467. 
This is an indeterminable species from Lyall Bay. It may possibly be 
the same as Halicornaria rostrata n. sp., as it has the front of hydrothecae 
produced into a pointed rostrum, as in that species.
