similar to that of Cladyodon, but is more compressed and has both 
anterior and posterior edges serrated to the base. 
Rhynchosaurus articeps, from the Keuper of Grinshill, Shropshire, 
was described by Owen in 1841 from a skull, but was further illus- 
trated by additional specimens, including other parts of the skeleton, 
by Professor Huxley in 1887. This form, which is allied to the 
recent Sphenodon, is also near to the Hyperodapedon, remains of 
which have been found in the Elgin Sandstone and also in the Trias 
of Warwick and Devon. Hyperodapedon was first made known by 
Professor Huxley in 1858, who described it in 1869, but more fully 
in 1887, from a fine example preserved in the British Museum. 
Telerpeton Elginense, the celebrated lizard of the Elgin Sandstone, 
was found in 1850 by Mr. Patrick Duff, and described by Dr. Mantell 
in 1851 as having amphibian affinities. Additional examples were, 
however, described by Professor Huxley in 1867, who showed that 
its affinities were with the lacertilia, and not with the amphibia. 
Telerpeton is probably closely related to the living Sphenodon. 
Stagonolepis Robertsont was really the first reptile found in the 
Elgin Sandstone; a series of scutes from Lossiemouth being thus 
named by Agassiz just fifty years ago (1843), but were thought by 
him to be the scales of a fish. The reptilian nature of this fossil 
was shown by Professor Huxley in 1858, and more abundant 
material has been described by the same writer in 1875 and 1877, 
which has established the crocodilian affinities of this Triassic 
reptile. 
Dasygnathus longidens is the name suggested by Professor Huxley 
for a jaw with long teeth from the Elgin Sandstone, which had at 
first been referred to Stagonolepis. his form Professor Huxley 
thought might be dinosaurian, but additional information is much 
wanted to establish its true affinities. 
The dicynodont remains noticed by the present writer at the 
meeting of this Association last year at Edinburgh have now been 
worked out, and the results, fully illustrated, will shortly appear 
in the Phil. Trans. of the Royal Society. Four forms nearly allied 
to Dicynodon have been named Gordonia Traquairi, G. Husleyt, 
G. Duffiana, and G. Juddiana. Another dicynodont more nearly 
related to the Ptychognathus of Owen, but with a short muzzle and 
no teeth, has been named Geikia Hlginensis. 
The peculiar horned reptile, resembling the Moloch lizard, but 
apparently most nearly related to the South African Pareiasaurus, 
has been named Elginia mirabilis. 
Work among the Hlgin reptiles is still going on, and two entirely 
new forms are now made known for the first time. One of these 
was found by Mr. James Grant, of Lossiemouth ; and, although the 
exact locality is uncertain, there is no doubt as to its being from 
the sandstone of the Elgin area. This specimen, which includes 
the skull (about three inches long) and the fore part of the trunk, 
is evidently related to Stagonolepis. 
The second new form was obtained by the Rev. Dr. Gordon from 
the Elgin Sandstone of Spynie Quarry, and will eventually be
