Family SPINTHERIDAE 
This family is known through a single genus, 
Spinther Johnston. The body is broad, flat, and 
sole-like. The entire dorsum is covered with 
transversely prolonged notopodial ridges; these 
are continued around the front to encompass 
the prostomial parts so that those of the two 
sides merge at the middle front. The ventral 
side of the body is papillated or smooth. The 
prostomium is a tiny, inconspicuous lobe, with 
or without eyes; it is set some distance back, 
between the notopodial ridges and immediately 
over the ventral mouth. There is a small, con¬ 
ical or subspherical, median prostomial antenna 
that largely covers the prostomium. The pro¬ 
boscis is a voluminous, unarmed, rosette-like, 
eversible organ. 
Parapodia are biramous. Notopodia are long, 
transversely arranged, dorsal ridges; they are 
provided with many spine-like setae that are 
arranged in transverse rows; they have entire or 
bifid tips. Neuropodia are long, lateral exten¬ 
sions of the body wall; they may or may not 
have a distal extension (called a cirrus); they 
are armed with one to several, strong, falcate, 
composite, yellow hooks that are encased in an 
embedded bundle of slender acicula (Fig. 1 c). 
The anal aperture is dorsal, near the posterior 
end of the body. 
In so far as known, all species occur on the 
surface of sponges, in shallow to moderate 
depths. 
Genus Spinther Johnston 
Spinther Johnston, 1845 
Oniscosoma Sars, 1851 
Cryptonota Stimpson, 1854 
Type S. oniscoides Johnston 
Three species, S. oniscoides Johnston, S. mini- 
aceus Grube, and S. arcticus Wiren, were recog¬ 
nized and described in von Graff’s revision 
(1888), but the first of these with some reserve 
because of the ambiguity surrounding John¬ 
ston’s description. Riddell (1909: 101-108) 
clarified this doubt, after a study of topotypes of 
S. oniscoides, and showed that von Graff’s first 
species is actually S. citrina (Stimpson), and 
that S. oniscoides Johnston, constitutes a fourth 
species. Since then, a fifth species, 5'. australi- 
ensis Augener (1913), has been described. 
Confusion still prevails (see Fauvel, 1923: 
140) concerning the specific names of von 
Graff, especially since the rules of nomencla¬ 
ture were not applied in the choice of acceptable 
names. Thus, although von Graff showed con¬ 
clusively that Oniscosoma arcticum Sars (1851)
