TRIASSIC FISHES FROM SPITZBERGEN 
Wimania? multistriata n. sp. 
(PL 8, figs. 2-7; PL 9) fig. I.) 
Under the name of W. multistriata I have grouped together a number of pieces, 
mostly fragmentary, of a large Coelacanthid (P. 238, P. 244 — 250, P. 252, P. 254, P. 674, 
P. 691). I have also provisionally included under this name a detached bone-plate (P. 2o3), 
for reasons given below. Besides these, all of which belong to the Geological Institute 
of Upsala, there were found in the material investigated by Hulke, 1873, which is kept 
in the Natural History State Museum, Stockholm, several fragments of a huge Coelacanthid, 
probably belonging to the species in question. 
W. ? multistriata has attained a very considerable size and in this respect it seems 
to be about equivalent to Mawsonia gigas Woodward (1907 a). One jugular plate, for 
instance, measures 12 cm in width, and may have been about 40 cm long. A number of 
other remains of the bones of the head, fins etc. are correspondingly large, although in 
most cases the state of preservation makes it impossible to give any figures of measurements. 
Nothing is known with regard to the shape of the body, but if this did not differ to 
any very great extent from the usual type, one might venture 
to estimate the total length of the larger specimens as about a 
couple of meters or perhaps even more. 
Membrane bones of the neurocranium and cheek-plates. 
The substitution bones of the primordial neurocranium are 
not preserved. Of the membrane bones there are the parieto-inter- 
temporals in a small specimen (P. 252) together with the supra- 
temporo-extrascapulars and a number of fragments of other 
indeterminable plates. 
The two parieto-intertemporals (text fig. 3 i A; Pa. it, PI. 8, 
fig. 2) are relatively long and narow. Their greatest width is 
little more than half their length. They meet medially in a 
straight median suture, and the lateral margin has posteriorly a marked sinus, into 
which the antero-medial part of the supratemporo-extrascapular is inserted. The ventral 
longitudinal lamella issuing from the ventral surface is well developed (text fig. 3 x B) 
though it is not vertical as in W. sinuosa, but is directed more ventro-laterally. I cannot 
say at present whether this is primary or is to be considered as having arisen through 
the effect of pressure during or after fossilization. 
The supratemporo-extrascapular bones (PI. 8, fig. 2) do not seem to show any essential 
deviation from those in W. sinuosa with regard to shape, but they are not well enough 
preserved for a detailed description to be possible. 
Both the parieto-intertemporals and the supratemporo-extrascapulars and probably 
also the other bones of the cranial roof are without ornament. On the other hand the cheek- 
plates (P. 252, P. 674) are furnished with fine tubercles, which may be rounded or somewhat 
lengthened, sometimes, too, bent into the shape of a kidney or an S. On certain bone-plates, 
especially in larger specimens, the tubercles seem to be present rather densely and the 
character of the sculpture consequently agrees pretty well with that of the scales, which I 
shall describe below. On other bones, on the contrary, the tubercles are distinctly sparse.
