OPHIOCREAS RHABDOTUM, 1 sp. nov. 
Rays 5. Disk 5 mm. in diameter, with arms about 78 mm. 
long. Very similar to the preceding species, but arms shorter and 
more slender, radial shields shorter and less prominent and teeth 
sharper and more regular. Only the first pair of tentacle-pores 
lacks tentacle-scales. 
Colour dull yellow, speckled and streaked on disk with blackish : 
a broad blackish stripe runs the length of the arm in the median 
line abactinally, but under the lens, even this stripe is found to be 
finely speckled with yellowish ; just above the tentacle-scales there 
is on each side of the arm, a very narrow and often indistinct 
blackish stripe. 
Off Jurien Bay, W.A., 80-100 fms. Two specimens, No. 
4,926. 
The larger specimen is the Type. 
As this form was taken at the same station with the preceding, 
I think it quite possible that it is only a colour phase of that species. 
But the colour difference is so marked, and the two specimens of 
each species are so distinctly characterised thereby, I have felt it 
was more satisfactory to designate them by different names. 
Further investigation on the West Australian coast is necessary for 
a correct settlement of the question. 2 
CONOCLADUS MICROCONUS. 3 sp. nov. 
Plate XXV. 
Rays 5, but in the type specimen there are 6. Disk, 35 mm. 
in the type, in the smaller specimen 27 mm. in diameter, with arms 
about 90 or 100 mm. long and 10 mm. wide at base; height of arm 
near disk, 5-6 mm. Radiating wedges of disk separated from each 
other by five (in the type, six) narrow deep grooves, which are

2 The two supposed species of Ophiocreas were obtained together in large 
quantities attached to one particular species of Hydroid, with which their 
arms were so much intertwined that it was very difficult to remove them, 
except in fragments. Whilst I entered them under two numbers, I made 
a note at the time that they were “ probably colour varieties of one 
species " — W. B. A. 
Gr. mikros — little ; konos — cone ; in reference to the small size of the cones 
on the disk,
