POPULAR SCIENCE REVIEW. 
merely ovo-viviparous, after the fasliion of those reptiles of the present day 
whose offspring are brought into the world alive and free, the large size of 
some, at least, of the young examples cited by Professor Seeley is hardly 
reconcilable with the idea of their embryonic condition. 
A New Type of Pterodactyles. — At the last meeting of the Geological 
Society Professor Seeley described the characters presented by the impression 
of the skull of an Ornithosaur in a slab of Stonesfield-slate from Kineton 
near Stow-on-the-Wold, the peculiarities of which are such as to induce him 
to found for it a new genus, to which he thinks it probable that most, if not 
all, the known Stonesfield-slate Pterodactyles may belong. It is distinguished 
especially by the great length of the roof of the skull posterior to the orbits, 
by the presence of a very deep constriction of the frontal region between 
the orbits, by the strongly marked sutures between the bones, and by the 
curiously crocodilian character of the plan of structure of the roof of the 
skull, which suggests the existence of a lower grade of Ornithosaurian 
animals than has hitherto been suspected. The genus appears to be allied 
to some forms of Rhcimphorhynchus. The author names the species, which 
is in the Oxford Museum, Rhamphocephalus PrestwicJii, and considers that the 
other bones of Ornithosauria discovered in the Stonesfield Slate support the 
generic separation of the group. 
New Fossil Crustacea. — On May 28, Dr. Henry Woodward communicated 
to the Geological Society descriptions of four new Fossil Crustacea possessing 
considerable interest. Three of them are regarded as Stomapods of the 
family Squillidse, and one of these is especially interesting, if correctly 
referred to that group, as carrying back the Squilliform Crustacea in time to 
the middle Coal-measures. The specimen was found by Mr. E. Wilson, of 
Nottingham, in a nodule of Clay-ironstone from Corsall, near Ilkeston, in 
Derbyshire, but is, unfortunately, very imperfect, consisting only of the four 
posterior abdominal segments and the telson. Dr. Woodward names it 
Necroscilla Wilsoni, and thinks it probable that it is allied to the genus 
Diplostylus, Salter, from the Coal-measures of the Joggins, Nova Scotia. 
A true Squilla was described under the name of Squilla Wetherelli from a 
specimen preserved in a phosphatic nodule of the London Clay of Ilighgate, 
forming part of the late Mr. Wetherell’s collection. It is of interest from 
its resemblance in characters to the existing species of the family, its nearest 
ally being a recent Australian species, unnamed, but related to the well- 
known Squilla Desmarestii. 
A second Squilla, this time from the Cretaceous deposits of the Lebanon, 
is also most nearly related to the Australian species above-mentioned, the 
segments not being ornamented with spines and ridges as in most recent 
forms. The specimen occurs in a collection made by Professor E. R. Lewis, 
of Beirut, consisting chiefly of the remains of fishes preserved in a compact 
cream-coloured limestone. It was named Squilla Lewisii. In the same 
collection there was the most interesting of all the species described by Dr. 
Woodward on this occasion, namely, a fossil king crab (named by the 
author Limulus syriacus ), well-preserved in a slab of the same cream-coloured 
limestone. From a palaeontological point of view the discovery of this new 
king crab is very important, as it helps to bridge over the gap previously 
intervening between the Jurassic Limuli of Solenhofen and those of our 
present seas.
