horizon, and in the " Olive group " with the Conidaria layer, hut 

 lower in position. From these Mr. Theobald had obtained at least 

 one glaciated boulder. A still newer band marked by boulders of a 

 red granite, the source of which was quite unknown, occurred in the 

 Tertiary beds above the Eocene Limestone of the Eange. 



The interest of Dr. Warth's discovery was enhanced by the con- 

 spicuous absence of known Devonian rocks among the formations of 

 Northern India, if not from Indian series generally, and in the hope 

 that some further determinations would be made, the specimens 

 kindly sent from the Punjab by Dr. Warth were handed over by the 

 author to the Museum of Trinity College, Dublin, through its 

 Curator, the Professor of Geology, etc., W. J. Sollas, D.Sc, LL.D., 

 who promised attention to the subject, and noted much similarity 

 between the contents of the Salt Eange Cretaceous deposits and con- 

 ditions, and those of Cambridge.

Mosasaurus gracilis, Owen, from the Irish Chalk. 



At a meeting of the Belfast Natural History and Philosophical 

 Society, held in their museum on Tuesday, February the 2nd, the 

 President, W. H. Patterson, Esq., M.E.I.A., in the Chair, a short 

 communication was brought forward by Mr. W. Swanston, F.G.S., on 

 the occurrence of remains of Mosasaurus gracilis, Owen, recently 

 presented to the Museum by Mr. Turner, Mountain Bush, in whose 

 quarries at "Whitewell the specimen was found. The fossil is por- 

 tion of the caudal vertebra}, consisting of three joints attached, very 

 closely resembling the specimen figured in the Palasontograpbical 

 Society's Journ. 1851, vol. viii. fig. 3. This is the first record of the 

 species from Irish strata. The quarries from which the specimen 

 was obtained are in the "White Limestone (Upper Chalk), most pro- 

 bably the zone of Ammonites Gollevillensis, representing, according to 

 Professor Ealph Tate, F.G.S., the Upper Chalk of Norwich, and the 

 " Craie de Meudon," and some of its fossils point to even a higher 

 parallel, that of the Maestricht Chalk (Quart. Journ. Geol. Soc. 

 London, 1865, vol. xxi. p. 86).

1. "On the Fossil Mammalia of Maragha, in North-western 

 Persia." By E. Lydekker, Esq., B.A., F.G.S., etc. 



The author alluded to the important memoirs of Messrs. Grewingk, 

 Pohlig, and Eodler on the Maragha mammalia, and having expressed 

 the hope that his notice would be regarded as an attempt to assist 

 rather than to interfere with their work, mentioned a collection of 

 specimens from Maragha sent by Mr. Damon to the British Museum. 

 He fully confirmed the conclusions already arrived at as to the 

 identity of many of the Maragha mammals with those of Pikermi, 

 and thought that Giraffa altica, Palceoryx Pallasi, Sas erymanthius,
