Dapedius monilifer (Agassiz). 
The British Museum contains specimens from the Lower Lias (planorbis 
zone), Barrow-on-Soar. The species is also recorded from the same locality by 
Morris.* * * § 
Dapedius cn'bis (Agassiz). 
Agassiz describes, tome ii., p. 218, and figures in the atlas, vol. ii., tab. 25^, a 
very ill-preserved example, minus the tail, of this species, from Barrow-on-Soar. 
The species is recorded from the same locality by Morris,* by Ansted,f and 
by Harrison, $ who states that, in the Lower Lias, “good specimens of a fish with 
a remarkably rounded outline, called Dapedius orbis, are often found.” 
The Dublin Museum possesses twenty-eight specimens from the Lower 
Lias of Barrow-on-Soar, purchased from the late Mr. Wm. Lee ; and the Derby 
and Warwick Museums each possess a specimen from the same place. 
The Leicester Museum contains many, including a small specimen (im- 
perfect) from Barrow, from the collection of the late Mr. Benwell Smith, and 
quite a number of portions of specimens presented by the Messrs. Ellis in 1889, 
each of which exhibits some characteristic lacking in the others, and it is highly 
probable that amongst these may be found species other than orbis ; but, as the 
taxonomy of Dapediiis { = Tetragonolepis, Agassiz) appears to be little known, 
and in a most unsatisfactory state, it may be well to await a revision of this 
genus, before attempting to differentiate the many specimens I have collected, 
of the so-called Dapedius orbis.

Cosmolepis egertoni (Egerton ex Agassiz’ MS.). 
This very rare fossil, which occurs in no part of the world save Barrow-on-Soar, 
is recorded from the Lower Lias at that place by Morris,§ by Egerton, || and by 
Ansted.f The British Museum contains the type and one other specimen, and in
