Girdles and fins. 
The fins are still extremely incompletely known in this species, as they are mostly 
represented only by detached lepidotrichia or parts that cannot be exactly defined. The 
lepidotrichia are often long - and always taper gradually distally. They are unjointed for a 
fairly long distance proximally, but it is uncertain ho^ great a part of their total length 
this distance represented. The joints (PI. 9, fig. 1) are mostly rather short and wide, 
sometimes even very short. I have not found any tuberculation or. striation on them, 
nor on the proximal unjointed part. The latter part often has, however, on each lateral 
side a longitudinal furrow with small rounded pits lying close together, and these pits 
possibly indicate that we have had free spines here articulating against the lepidotrichia 
in the same way as, for instance, in Macropoma. — A loose pelvic plate (P. 20S) may 
also belong to W.? multistriata. This has, as shown in PI. 8, fig. 7, a shape that resembles 
that of Coelacanthus granulatus (Reis, 1888, PI. IV, fig. 7) very closely, and since, as I 
pointed out in the general description above, the type species of the genus Wimania 
at. least resembles in several respects the typical Coelacanthus ^ 
species, it is also most probable that the bone-plate in question 
belongs to some Wimania species, and, to judge from its size, it 
could in this case scarcely be any other than W. ? multistriata. 
Squamatiou. 
Together with the other remains of this species there are 
often found scales which sometimes attain a length of close upon 
5 cm. A distinguishing feature of the scales is the posterior 
margin, which has a definite though rounded corner (textfigs.34 A, 
B, PI. 8, figs. 4—6; PI. 9, fig. 1). In other respects their appearance 
is pretty variable. In some of them (e. g. those figured in text 
fig-. 34 A and Pl. 7, fig. 4), the exposed part of the lateral surface is rather small 
compared with the covered part, and at the same time the upper and lower margins 
run in a continuous arch backwards to the corner mentioned. Other scales, on the con¬ 
trary, have the exposed part of the lateral surface strikingly larger in comparison 
with the covered part and at the same time the appearance of the dorsal and ventral 
margin is also different, as is clearly shown in text fig. 34 B and PI. 8 , fig. 5. Transi¬ 
tional forms between the two extreme types just described are common. The sculpture 
consists of a very large number of fine striae, lying close together, which generally run 
parallel to the longitudinal axis of the scales. Not infrequently the striae may, however, 
be so long that they reach across the whole exposed surface. They are all, as a rule, 
somewhat undulating.

Remarks. — W.? multistriata is well characterized as an independent species by 
the nature of the ornament of its superficial head-bones and scales, the development 
of its lepidotrichia, and lastly also by its considerable size. It certainly reminds us, as 
we have seen, of the type species of the genus Wimania in a great many respects, but, 
on account of the deficient character of the material at our disposal, it is impossible as
