DESCRIPTION OF THE SPECIES. 
Psilaster acuminatus Sladen? 
Psilaster acuminatus Sladen, ‘‘ Challenger”? Report, Asteroidea, xxx, 
1889, p. 225. 
Station 7. 
Four specimens were obtained, the largest of which measures 
R. = 70mm., r. = 15mm., breadth of arm at base 16mm. The 
ratio of r. to R. is rather less than 1 to 4°6. The colour of the dried 
specimens is pinkish-brown on the upper surface. Of these four, one 
was obtained off the south coast of the South Island, at a depth of 43 
fathoms; the three others had no number attached, but were no doubt 
obtained off the east coast of the South Island. 
[In addition, I have a specimen in the Otago University Museum 
which shows the characteristic adpressed inframarginal spines better 
than the above, for it is uninjured. ]

North Island: and (‘ Challenger’), near western entrance. to Cook

Station 89. 
Two arms, or portions of arms, were amongst the material dredged 
off Cape Runaway, on the east coast of the North Island, from a 
depth of 66-94 fathoms. The long, slender, tapermg form of the 
arms recalls the figure of L. africana Sladen [35, -p. 256], which, 
however, comes from the Atlantic. I refrain from giving a name 
to these fragments, but will put on record the description, which may 
lead to the identification of the species by others who have access 
to more literature than is available here. 
The arm is 35 mm. in length and 6 mm. across the broader end, 
tapering to a point. 
The abactinal surface is densely covered with small paxilli con- 
«sisting of rough, thorny spines; each plate bears a central rather 
larger one surrounded by a circle of nearly horizontally disposed 
spines. 
* T enclose in square brackets New Zealand localities in addition to those at 
which they were obtained during this expedition. ‘‘O.U.M.” means that a 
specimen is in the Otago University Museum, and “ F.” that Mr. Farquhar has 
recorded it. 
+ The figures within square brackets refer to the bibliography at the end of 
the paper.
