Gazella brevicornis, from the Miocene of Pikermi, has the horn- 
cores strongly curved and not so much flattened as in our fossil, and 
at the same time they taper more rapidly towards the summit. 
Antilope deperdita, from the Miocene of Mont Léberon, very 
closely resembles the last-named species, haying the horn-cores 
strongly curved. The brain also of this species, as described by 
Gaudry, has the frontal convolutions more complex than they are in 
our fossil. 
Antilope hastata, from the Pliocene (?) of Montpellier, besides 
being three times as large, has the horn-cores reclinate with a strong 
anterior and posterior limiting ridge. 
Tragoceros Valenciennesi, from the Miocene of Pikermi, seems to 
have been about the same size as our fossil ; but the horn-cores are 
too reclinate, show no basal pit, and are set wider apart on the 
skull. 
Paleoryx parvidens, also from Pikermi, is larger than the Crag 
species, has the horn-cores more curved, and more nearly round in 
section. 
This comparison of the remains of the Norwich-Crag Antelope 
with the recent and fossil forms shows that it agrees more closely 
with some of the Gazelles of the present day than with any of the 
known fossil species. And seeing that almost all its known 
- characters, including the triangular frontal fossa and supraorbital 
foramen, as well as the arrangement oi the brain-convolutions, are 
to be found in one or other of the recent Gazelles, there is ample 
justification for placing it inthesame genus. But inasmuch as this 
English Gazelle differs in certain points from each of the forms 
which it most nearly resembles, a new specific name must be found 
for it; and that of Gazella anglica is suggested as being most 
appropriate. 
The jollowing Note on the horizon from which these specimens 
were obtained has been kindly appended by Mr. H. B. Woodward, 
who is so well acquainted with these East Anglian deposits; and 
further information will be found in his Survey Memoir ‘On the 
Country around Norwich, to which allusion has already been 
made. Mr. Woodward says :— 
‘¢ The specimens described by Mr. Newton were obtained from the 
lower portion of the Norwich Crag at Thorpe, near Norwich. The 
basement-bed of this deposit, asis well known, generally consists of 
a bed of flints, of which the majority are more or less rolled, though 
some appear unworn. Pebbles of quartz and quartzite are occasion- 
ally met with in the bed; and at Thorpe I found in it a worn frag- 
ment of Gryphea dilatata. At this locality the Crag Mollusca appear 
abundantly in the bed; and they even occur in crevices of the Chalk 
beneath, the surface of which, in places, is bored by marine shells and 
Annelides. This basement-bed has been called the Mammaliferous 
Stone-bed by Mr. John Gunn, because it is held that most of the 
mammalian remains of the Norwich Crag have been obtained from it. 
During a residence of four years at Norwich I frequently visited the
