a shore deposit. In the Jura Salinois they are known as the 

 "Marnes a Plicatules." They are also well marked in 

 Wurtemberg and other parts of Germany as well as in Hungary, 

 but only on the coast lines, and conterminous with the areas 

 of certain liassic basins. A review of the fossils indicates a zone 

 of life, lying in shore, or near the coast line, belonging to the 

 Laminarian zone of Pi'ofessor Forbes (about 15 fathoms deep). 

 Many of these forms are new, and all are interesting. It may 

 be remarked that the division of the Middle Lias here treated 

 of, has hitherto been much overlooked by geologists, who, 

 besides, have often regarded these beds as appertaining to the 

 Upper Lias, from which they are sharply divided off,- or else they 

 have grouped them with the so-called Marlstone or " Margaritatus 

 zone," and thus they have come to be esteemed of little or no 

 significance. 



While treating of this paper of Dr. Ssitthe's, it may not be 

 out of place to draw attention to other work by Dr. Smtthe in 

 the same field, which should not be passed over without notice 

 by Cotteswold geologists. 



The part just issued by the Palseontological Society, contains 

 a supplement, or rather, the first instalment to the supplement 

 to the British Jurassic and Triassic Brachiopoda, which deals 

 very minutely with the Cotteswold country, especially Church- 

 down; the preparation of which has involved an amount of 

 painstaking work on the part of all concerned, that is truly 

 astonishing. This work, in which our colleague. Dr. Smythe, 

 has been intimately associated with Mr. Davidson, has cleared 

 up many doubtful points, and has established, without doubt, 

 the very great importance of Churchdown, as a Palaeontological 

 station. 



While on this subject I would draw attention to the fact, that 

 one result of the labours of Mr. Davidson and Dr. Smythe in 

 this field, has been the settlement upon a firm basis, of the 

 vexed question of the affinities of ' Terebratulce punctata,' of 

 which, appears faithfully figured, a new form which occurs at 

 Haresfield, from which locality the variety has received the 

 name of Haresfieldensis. The result is that ' T. punctata '
