E. Ray Lankester — On Scaphaspis Knerii. 399 



(Dr. Kner having lately died) came upon the specimens. They had 

 been in the Museum twenty years before Kner described them ; the 

 exact locality from which they came is Zaleszczyk, on the Dneister, 

 upon the borders of Eussia and Galicia ; a very inaccessible place and 

 one of which the geology appears to be very little known, excepting 

 that there are both true U2:)per Silurian and true Lower Devonian 

 beds there, with complete transition. An odd specimen w^as with 

 the three bits from Zaleszczyk, which had not come with them and 

 seemed to me to be undoubtedly from Herefordshire. The resem- 

 blance, however, of the rock in which the Galician specimens were 

 embedded to our cornstones was striking ; the figured specimen was 

 in matrix having a little- more of a limestone character. Kner's 

 figure, of which a woodcut copy is given in the Monograph of 

 CephalaspidcB, is bad and misleading.^ The specimen is much more 

 like Scaphaspis Lloydii than is the figure, the central ridge not being 

 marked at all as I had thought from the drawing. In fact, the 

 resemblance to &c. Lloydii is exceedingly close, the posterior corners 

 of the shield, however, in the G-alician species being somewhat 

 produced, instead of quite rounded off, as in. So. Lloydii. 



Two interesting things- were noticed in the specimens. Firstly, 

 that a form like Pteraspis rostratiis is also present in one of the 

 blocks ; and, secondly, that in- the block with Kner's figured speci- 

 naen there are marine shells. An Orthoceras is lying almost against 

 the fish-shield, which is very perfect, and there are two Lamelli- 

 branchs in close proximity. We must not therefore conclude from 

 the corn- stones and Scotch beds that the CepJialaspidm were exclu- 

 sively lacustrine or fluviatile. The Galician specimen is tolerably 

 perfect and has not been much knocked about by sea waves, as the 

 Steganodietyan fish-remains of Cornwall and Devon seem, to have 

 been before deposition. — E.E.L.

 ~VrO very perfect example of this species appears to have been 

 JJM collected ; the one figured in my plate was kindly given to me 

 by Sig. Meneghini. The shell is ovate and smooth, about ten lines 

 in length by nine in breadth ; the valves are moderately convex, 

 and there exists a deepish sinus in the ventral valve to which corres- 

 ponds an elevation or fold in the opposite one. Ter. Voglianei occurs 

 in a yellowish marl in the Lower Miocene at Dego, and along' with it 

 is found a small Terebratulhia, which may probably be a variety of 

 T. caput-serpentis. 



I would beg leave to suggest that Italian Palseontologists should
