This species was hitherto known only from the coast at Wel- 
lington, where Farquhar collected some specimens understones, 
near low-water mark. Although I have been collecting at the same 
place and also in other places of the New Zealand coast in the 
littoral region, I have not come across this species there. — It is 
interesting that it has now been proved to be rather widely di- 
stributed in the seas off the North Island of New Zealand, in depths 
until at least 55 fathoms. 
The specimens on which Clark had to base his description 
being quite young, it will be necessary to give some additional

remarks on the characters of this species as shown by the adult 
specimens (Fig. 32). 
The larger of the specimens before me measure 10 mm dia¬ 
meter of disk, the arms, which are rather thick and stiff being ca. 
30 mm long. Disk covered with somewhat thickened scales, among 
which the primary plates remain more or less distinet, according 
to the varying size of the smaller secondary plates surrounding 
them. Generally there is a median series of 3—4 large plates in 
each interradius, but the series is sometimes indistinet, on account 
of smaller plates intruding among the larger ones. The small ovoid 
radial shields are widely separated by a series of three squarish 
plates, almost as large as the interradial ones. Adjoining the distal 
one of this series is a slightly larger plate outside each radial 
shield, these three plates together forming a conspieuous band across 
the base of the arm. The dorsal olates are about twice as broad as
