Dr. R. H. Traquair—New Ooal-measure Paleoniscide. 251 
The Sponges obtained from these rocks, which had been described 
as Monactinellid forms by v. Dunikowski, are shown to be really 
Lithistid sponges, this author having mistaken the original fibres for 
canals, and the infilling matrix, in which detached spicules occur, for 
the fibrous skeleton of the sponge. 
EXPLANATION OF PLATE VIII. 
. Part of a vertical section of Pemmatites macropora, Dunik., showing the 
disposition of the translucent skeletal fibres and the dark matrix. Hn- 
larged four diameters. From the Productus-chert beds of the Permo- 
Carboniferous series, Bell Sound, Spitzbergen. 
» 2. Part of a section from the same specimen, enlarged twenty diameters, 
epowing lithistid spicules in the translucent fibres, as well as crystals of 
calcite. 
. Detached spicules from the same section, enlarged sixty diameters. 
. Spicules from the same, showing their mode of union with each other. 
Enlarged sixty diameters. 
» 5. Two detached spicules occurring in the translucent fibres of Pemmatites 
arcticus. Enlarged sixty diameters. Drawn from a section prepared by 
v. Dunikowsk1. 
» 6. Two spicules from the translucent fibres of P. verrucosus, Dunik., similarly 
enlarged. Also from one of Dunikowski’s sections. 
» 7. Part of a section of P. latituba, Dunik., from the Cyathophyllum-limestone 
at Gypshook, Bell Sound, showing spicules (now partially obliterated) in 
the translucent fibres. Enlarged sixty diameters. Drawn from a section 
prepared by v. Dunikowski. 
» 8. A section of the White Chert from Templeberg, Spitzbergen, showing its 
structure of sponge-spicules irregularly intermingled together. Enlarged 
forty diameters. 
», 9. Two detached cylindrical spicules of Renitera clavata, Hinde, from the White 
Chert of Templeberg. Enlarged sixty diameters. 
,, 10. Detached cylindrical spicules of Reniera bacillum, Hinde, from a section 
of the Productus-chert at South Axel’s Island. Hnlarged sixty diameters. 
,, 11. A fusiform acerate spicule from a section of a chert pebble (probably from 
the Permo-Carboniferous), from the Tertiary gravels of Nordenskiold’s 
Berg. Enlarged sixty diameters. 
», 12. Flesh spicule of hexactinellid sponge from the same pebble. Enlarged 
175 diameters. 
», 13. Lithistid spicule of Doryderma Dalryense (2), Hinde, from the same pebble. 
», 14. 15. Modified hexactinellid spicules. Enlarged sixty diameters. From 
Axel’s Island and Green Harbour, Productus-chert series.

By Dr. R. H. Traevarr, F.R.S., F.G.S. 
(For No. I. see Gzou. Mac. Dee. III. Vol. III. 1886, p. 440.) 
Elonichthys Binneyi, sp. nov., Traquair. 
F this I have seen only two specimens. One of them, slightly 
longer than the other, measures 33 inches in length up to the com- 
mencement of the caudal fin, which is deficient in both; the greatest 
depth of the body 44 inch, the length of the head nearly the same. 
The dorsal fin is opposite the interval between the ventral and the 
anal; both dorsal and anal are triangular acuminate in shape, with 
delicate rays which at first are somewhat distantly articulated, the 
joints being ornamented with one or two longitudinal sulci. The 
pectorals are not seen in either specimen, but the smaller of the two 
shows a well-preserved ventral, which is pretty large, and acuminate 
in shape.
