POPULAR SCIENCE REVIEW. 
note. The material for this note was a slab from Cowleaze Chine, con- 
taining portions of two individuals of Hypsilophodon Foxii, one consisting of 
a skull with a great part of the vertebral column, the other of a portion of 
the vertebral column. The author described some details of the structure 
of the skull, and especially the palatal apparatus. The pterygoids, which 
are not mesially joined, have a stout body, the posterior border of which 
bears a very large basi-syphenoidal process, and the left pterygoid retains the 
root of a strong quadratic process, in front of which the hollow outer border 
runs out into an ectopterygoid. In front of the pterygoids the palatines 
are partially visible, also separated by a fissure. Of the eight vertebrae, the 
three last are firmly anchylosed, and the seventh and eighth form part of the 
sacrum. They are constricted in the middle, and their transverse processes, 
which spring from the junction of two vertebrae, are bent backwards, 
joining the dilated outer end of the transverse processes of the next ver- 
tebra, including a large sub-circular loop. The second fragment of a 
vertebral column, which belonged to a smaller individual, includes the 
sacrum and several vertebrae. Near the skull the slab contains several very 
thin bony plates of irregularly polygonal form, regarded by the author as 
dermal scutes. In connection with the question of the generic rank of 
Hypsilophodon, the author stated that in Hypsilophodon the centre of the 
sacral vertebrae are cylindroid, and rounded below, whilst in Iguanodon they 
are compressed laterally and angulated below. 
Death of Professor Reuss. — Geologists will be sorry to learn of the death 
of this eminent worker. He was a Fellow of the Geological Society of 
London, and he was the author of various papers on the Crustacea and 
Foraminifera. 
A New Lemur from the Phosphate Reds of Quercy. — M. H. Filhol points 
out, in a note to the French Academy (says “ The Academy ”), the more im- 
portant peculiarities of the cranium of another new genus of the family 
Lemuridae, lately found in the phosphate beds of Quercy. The interorbital 
space is wide, and differs much from that of the Lori. The orbits are large, 
and indicate an animal of nocturnal habits ; the temporal crests are united 
posteriorly to the frontal, while in the Nycticbbes they are directed back- 
wards without being united. The teeth are not so sharp as those of the 
Lori, and the first premolar of the upper jaw is far less developed. The 
molars bear a great resemblance to those of the Galogo, but in that genus 
there is an interval between the first and second upper premolars, and the 
first upper premolar is very stout and presents the aspect of a canine, 
neither of which peculiarities is noticed in this fossil. The form of the 
lower maxillary is the same as that of Galogo , and the tympanic bone is 
also similarly developed. This fossil, to which M. Filhol assigns the name 
of Necrolemur antiquus, is closely allied to the Galogo, though it also presents 
some affinities with the Lori. 
Does the loord “ Sarsen ” mean Rocks ? — A writer, who signs himself 
“ H. F.”, thus writes on this subject in the ‘‘Geological Magazine” (Feb- 
ruary). He says it was supposed by Dr. Stukeley that the word Sarsen 
came to us from the Phoenicians, and other writers since his time have 
adopted it as such ; but the greatest authority of the present day confutes 
the opinion, and states “ that no word in the English language is of Phoe-
