1002 The American Naturalist. [ November, 
luscoidea and Arthropoda have one species referred to each, of which 
the first only is known; the others are either indeterminate or new. 
(Proceeds. Biol. Soc Wash., 1893.) 
The jaw of a new carnivorous Dinosaur from the Oxford Clay of 
Peterborough, Eng., is figured and described by Dr. Lydekker in the 
Quart. Journ. Geol. Soc., Aug., 1893. It is of large size and solid 
structure, and appears to be nearly allied to the 'Thecodontosauridae. 
It differs from the described genera of that family by the marked ' 
deflection of the mandibular symphysis. Dr. Lydekker accordingly 
refers it to a new genus under the name Sarcolestes leedsii. 
Professor T. R. Jones notes the discovery of 15 fossil Ostracoda, 
13 of which are new, from the Upper Cretaceous series of Wyoming and 
Utah. Nearly all represent either fresh water or estuarine forms. 
Professor Jones has described and figured these interesting specimens 
in the Geol. Mag., Sept., 1893. At a recent meeting of the London 
Geol. Soc., Mr. E. A. Walford described some forms of Bryozoa from the 
spinatus zone of the Middle Lias near Banbury, Eng. The new mate- 
rial shows the opercular aperture, and the opercula in situ with append- 
ages and supraoral ovicells characteristic of the Cheilosiomata. In 
addition he found giant cells (cistern cells) of form quite dissimilar 
from the ordinary zooecia and probably reproductive. The name 
Cisternophora is suggested for the genus of which several forms were 
described (Geol. Mag., Aug., 1893.) 
Cenozoic.—Captain F. W. Hutton questions the propriety of the 
name, Dinornis queenslandie, given by C. W. DeVis in 1884 to a 
struthious femur found at King’s Creek, Darling Downs. Captain 
Hutton is inclined to refer the fossil in question to the Casuariidz since 
it possesses the posterior projection of the trochanterial surface, a char- 
acter lacking in the Dinornithid:e and Apterygidse, but present in the 
femora of both the Cassowary and the Emu. (Proceeds. Linn. Soc., 
N. S. W., 1893.) 
The skull of a Lemuroid mammal found in the shell-marl in the south. 
west coast of Madagascar has been determined by Dr. Forsyth Major 
to be that of a gigantic Lemurid related to the extinct genus Adapis 
as well as to the existing Lemurids. The brain-case is small, the thick- 
ening of the bones of the skull is very remarkable. The tritubercular 
molars and premolars approach closely some Malagasy Lemu- 
rids. Dr. Major names this new form Megaladapis madagascariensis.
