broken up; all the plates resemble those of the abactinal 
surface. Papule occur everywhere except between the 
adambulacrals, and on distal half of ray, between the adam- 
bulacral series and the adjoining actinolateral series. The 
granulation on the actinolateral plates near the mouth is 
coarser, more angular and more widely spaced than elsewhere. 
Adambulacral plates more than 70, wider than long ; furrow 
margin with 3 (distally 2) stout, prismatic, blunt spines, 
rather more than a millimeter long ; back of this series is a 
second of 2 or rarely 3, short, stout, angular spinelets or 
granules ; external to them are 5-8 smaller, angular granules 
similar to those on the actinolateral plates ; except near the 
mouth, these are usually in two series with 1-3 granules in 
the inner and 4 or 5 in the outer. Oral plates not conspicuous 
or peculiar, the marginal and surface spines being essentially 
like those on the adambulacral plates, though longer, more 
pointed and more sharply prismatic. No pedicellariz any- 
where, unless pairs, trios and quartettes of low, angular 
spinelets, more or less appressed to each other, on some of the 
plates near the mouth, are to be so interpreted. Colour (dry), 
dirty brownish-white. Three specimens. 
The form and size of this Fromia, in connection with its 
comparatively uniform granulation and its adambulacral 
armature, easily distinguish it from the other members of the 
genus. Ido not feel certain that the Western Australian speci- 
men is conspecific with those from Tasmania ; it has R=65 
mm.; r=l16mm.; br=16mm.; brat middle of ray 11 mm., 
and at tip 3 mm. ; hence R is only 4 r, and only 4 br; more- 
over, the arms are little flattened and taper uniformly to the 
slender tip, while there are, as a rule, 3 spines in the second 
adambulacral series. These differences are so slight, it is 
sufficient to mention them here and await more abundant 
material. Iam further constrained to do this because there 
is a Fromia in the Museum of Comparative Zodlogy collection, 
from Westernport, Victoria, the gift of Mr. J. Gabriel, which 
is certainly very near to the present species. In it R=65 
mm., and r and br are 16 mm., but br at middle of ray is 13 
mm., and at tip is nearly 4 mm.; hence the individual is 
much stouter in appearance than either the Western Australian 
or Tasmanian specimens ; the granulation and adambulacral 
armature also are noticeably coarser and the papulz, especi- 
ally on the actinal surface, seem larger; the terminal plate 
and adjoining marginal and abactinal plates are perfectly 
smooth, but it is possible that the granulation has been 
accidentally rubbed off. A good series of Fromias from the 
western and southern coasts of Australia, and from Tasmania,
