Some specimens were dredged in Paterson Inlet, Stewart Isl., 
j n io—30 meters, and off Stewart Island in 40 meters, in Novem- 
ber 1914. I further succeded in dredging a series of specimens 
of various sizes, from quite young to fullgrown, in the entrance of 
Wellington Harbour in 10—12 meters depth. (These latter were 
partly used for embryological studies; comp. the authors work „Stu¬ 
dies of the development and larval forms of Echinoderms, 1921. 
p. 117). Finally, I have received from Captain Bolions some 
specimens of various sizes, mainly naked tests, from the Foveaux 
Strait and from Cooks Strait (ca. 90 meters). This fairly rich ma- 
terial enables me to give some additional information of this very 
interesting Echinoid. 
The characters of the test are fairly well known. I would only 
point out a characteristic feature in the arrangement of the ambu- 
lacral pores near the peristome (the ,,floscelle“). The three adoral 
pores are in a straight line; from the fourth the pores make an 
outward curve, the ambulacra being from here about twice as broad 
as in the innermost part. At the same time a doubling of the pores 
takes place so that an outer, close series and an inner, more open 
series are formed, the latter forming a direct continuation of the pore 
i) i am not inclined to agree with H. L. Clark that the familiar name 
Echinobrissus has to be abandoned, because it is pre-Linnean. But .1 
cannot enter here upon a discussion of this or other nomenclatura 
questions.
