appears that much may be expected of future investigators of these 

 curious microscopic forms. The not unfrequeut occurrence of lengthy- 

 lists of synonyms, especially at pages 33, 37, 39, and 41, may be re- 

 ferred to as an indication not only of the interest taken in this group 

 by the author and his friends (Messrs. S. V. Wood, T. R. Jones, and 

 W. Harris) to whom he refers in the Preface, but also by numerous 

 naturalists of ancient and modern times. Some of the genera appear 

 to be common to several formations, e. y. Textularia, coming down 

 from the Carboniferous Limestone and Permian to the Tertiary and 

 Recent Epochs (and we may add that this genus occurs also in the 

 Upper Silurian); but others are limited in their vertical range, and 

 furnish more reliable characteristic species for the geologist. Among 

 these latter the Nummidite is pre-eminent ; although the important 

 exceptions of a few peculiar ancient Nummulitoid forms, — from the 

 Upper Jurassic of the Dep. de la Mouse (Buvignier), the Lias of 

 Fretherne, Gloucestershire * (Jones), and the Carboniferous Lime- 

 stone of Miatschlous, Russia (Rouillier), as well as another, similar 

 perhaps to the last, from the Upper Silurian of Shropshire, — must 

 not be lost sight of by the palaeontologist. The specific forms of 

 the Nummulite, though very closely allied and subject to individual 

 vagary and local variations, are highly characteristic, and play an 

 important part on the tertiary stage. A masterly sketch of the 

 zoological and geological relations of this interesting genus, com- 

 prising a review of M. D'Archiac's monograph, occupies several 

 pages of the Presidential Address delivered to the Geological Society 

 of London, February 17, 1854, by the late and most sincerely 

 lamented Prof. E. Forbes. 



In the former edition both the Bryozoa and the Anthozoa were 

 included mider Zoophyta. The former (so often confounded by 

 amateurs and others with Corals, and not unfrequently also erro- 

 neously termed Corallines), being now regarded as moUuscan in 

 their relations, are separately grouped. The Zoophytes, as they now 

 stand (Anthozoa or Corals), exhibit a very extensive augmentation 

 of species, resulting from the labours of Messrs. Lonsdale and M'Coy, 

 and their French coUaborateurs, MAL M.-Edwards and J. Haime. 



Li noticing the present advanced state of our knowledge of the 

 fossil Echinodermata, as exhibited in the ' Catalogue,' we have again 

 to refer to one whose loss the scientific world deplores and whose 

 early departure bereaves so many sorrowing friends. Prof. E. Forbes 

 and Messrs. Austin, M'Coy, and Wright have worked well in this 

 department ; the addition of the Cystidese and the very complete and 

 well-determined hst of the other forms render this portion of the 

 ' Catalogue ' of the greatest value. Not only for a large proportion 

 of the material of this list, but for its arrangement and revision, we 

 are indebted to the lamented chief of British palaeontologists. The 

 chief additions to the Annelida are palaeozoic species; and several 

 neozoic species are brought into position under Vermicularia.
