lyidce, in which the bony carapace is covered with symmetrical 

 horny scutes, including Turtles, Emydians and Tortoises ; 2. Pelto- 

 chelyidcB, in which the bony carapace has a granular surface- 

 structure and is covered with an undivided dermis without scutes, 

 including only the Trionychidae ; and 3. the Dermatochelyidce, in 

 which the carapace is not developed, but is functionally repre- 

 sented by a bony skeleton within the skin, as in Sphargis and 

 Psephophorus. 



3. " On the Occurrence of the Glutton (Gulo luscus, Linn.) in the 

 Forest-bed of Norfolk." By E. T. Newton, Esq., F.G.S. 



Remains of the Glutton have hitherto been obtained only from 

 cave-deposits. The author has lately received from Mr. R. Eitch, 

 of Norwich, a portion of the lower jaw of this animal obtained 

 from the Forest-bed of Mundesley, Norfolk. The specimen consists 

 of about 2 inches of the left ramus, bearing the first true molar and 

 the hinder half of the fourth premolar in place. The jaw is smaller 

 than in average specimens of the recent Glutton, but presents all 

 the characters of the species, as described in detail by the author. 



4. " A Review of the Family Diastoporidae, for the purpose of 

 Classification." By George Robert Yine, Esq. Communicated by 

 Prof. Duncan, F.R.S., F.G.S. 



This family of the Cyclostomatous Polyzoa, never very prolific, 

 has representatives from the Lower-Silurian era to the present time, 

 and is now northern and of deep-sea habit. The author discusses 

 the limits of the family, and gives a list of the recent and fossil 

 genera and species included in it. He points out that there are im- 

 portant differences in the Palaeozoic forms, several of which, though 

 he leaves them provisionally among the Diastoporidae. he considers, 

 on fuller examination, will have to be removed. The author de- 

 scribes the characteristics of some Palaeozoic genera of true Diasto- 

 poridae. 



5. " On Annelid Jaws from the Wenlock and Ludlow Formations 

 of the West of England." By G. J. Hinde, Esq., F.G.S. 



Referring to his paper on Annelid-jaws from the Palaeozoic rocks 

 of Canada and Scotland (Quart. Journ. Geol. Soc. vol. xxxv. p. 370), 

 the author in this paper announced the discovery of similar objects 

 in the Silurian deposits of Dudley, Much Wenlock, Iron Bridge, 

 Stoke Edith, and near Ludlow. He noticed from these Silurian 

 rocks seven species of Eunicites, two of which, E. curtus and E. un- 

 guiculus from the Wenlock, are new ; nine species of CEnonites, of 

 which six, namely (E. regnlaris, naviformis, prceacutus, and tiibii- 

 latus from the Wenlock, (E. insignificans from the Upper Ludlow, 

 and (E. aspersans from the Wenlock and Upper Ludlow, are described 

 as new ; seven species of Arabellites, four of which are new, namely 

 A. extensus, spicatus, and obtusus from the Wenlock, and A. anglicus 

 from the Wenlock and Upper Ludlow ; further, Lumbriconereites
