probably three, represent new forms, one of which may ultimately 
require a new generic name to emphasise its peculiarities. There 
are thus not less than 15 new species in this small collection, or 
more than a fourth of the total number. Of the others, at least 22 
are not known from outside the Australian region. As 5 are not 
certainly identified, it follows that of 53 species, 37 or 70 % are 
characteristic of Australia, certainly a very notable fact. Of course, 
further knowledge of both the Australian and East Indian faunae, 
will alter these figures, perhaps materially, but they are at least 
suggestive of the remarkable echinoderm fauna which awaits further 
study on the western coast of Australia. 
Finally, the collection at hand is notable for the presence of 
many species whose occurrence on the western side of Australia 
was not previously known, and in some cases at least was hardly to 
be expected. Among the starfishes, the most notable case is that 
of Anserepoda rosacea, previously known from Japan and the Bay of 
Bengal. Among ophiurans, there are two species, Pectinura dyscrita 
and Ophiothrix spongicola, previously known only from New South 
Wales. Among echini, the occurrence of a Temnopleurus is par- 
ticularly remarkable, while the presence of Tretocidaris bvacteata, 
previously known only from the East Indies and Japan, is most 
interesting. 
Holotypes of the new species described in this paper are in the 
Western Australian Museum at Perth, but cotypes of ten of them 
{wherever the holotype was not the only specimen) are now in the 
Museum of Comparative Zoology. 
CRINOIDEA. 
There are only five crinoids in the collection. One of these 
(No. 4922) is a damaged calyx with only the basal part of the arms, 
and hence is not identified, but it is certainly not one of the Comas- 
teridae. The other four represent four different species, but all 
belong to the single family Comasteridae. The chief interest of 
these crinoids lies in the fact that one of the species is new to the 
fauna of Australia, not being included in the list of “Recent 
Crinoids of Australia ” published in 1911 by Mr. Austin Hobart 
Clark. 1
