these conical and compressed teeth attnched to what seems to be 

 a premaxilla. 



On comparing these teeth with those of the recent Chrysophrys 

 aurata it will he found that although there is a general resemblance 

 they a,re not precisely of the same form. The largest recent 

 specimen I have been able to examine has the teeth nuich smaller 

 than those fiom tlie Crag. Moreover, I have seen no specimen 

 from the English Crag corresponding with the large oval tooth 

 found in each jaw of Chrysophrys aurata. 



Prqf. Van lieneden in 1871 (Bull. Ac. Roy. Belg., Ser., 2, Vol. 

 XXXI., p. 503) proposed the name of Chrysophrys Hennii for 

 some teeth from tlie Antwerp Crag ; but as he has given no 

 characters, or any good reason for separating them from the 

 recent species, his name cannot be adopted for our specimens. 



Dr. E. Sismonda (Mem. R. Ac. Sci. Torino, Ser. 2, Vol. X., 

 p. 15, 1846) described some oval flattened teeth from beds at 

 Antigiana, Piedmont, possibly of Pliocene age, to which he gave 

 the name of Chrysophrys Agassizii, but, as no such oval teeth 

 have been met with in the English Crags, comparison cannot he 

 made. 



Seeing that the name of Chrysophrys has been used for these 

 English Crag teeth, I purpose provisionally to let them remain 

 under that genus, although the evidence is insufficient for definite 

 identification. 



Ill Britain these Chrysophrys teeth have been recognized in the 

 Red Crag Nodule-bed of Woodbridge, Waldringfield, and elsewhere 

 in Suffolk. There is one tooth in the Museum of Practical Geology 

 from the true Coralline Crag of Gedgrave. Mr. J. Reeve has 

 specimens from the Norwich Crag of Bramerton, and Mr. Lamplugh 

 possesses examples from the Bridlington Crag. A specimen from 

 the Weybourn Crag of East Runton is in the Museum of Practical 

 Geology, and was figured in the Survey Memoir. (Vert. Forest 

 Bed, Plate xix., fig. 12.) On the continent teeth referable to this 

 genus have been found in the Pliocene at Montpellier, Roussillon, 

 Herault, Antwerp, and Piedmont. M. Gervais (Zool. Pal. Fr., 

 Edit. 2, p. 514, 1859), has also recorded them from the Eocene and 

 Miocene of various localities in France, Malta, &c.

The enlarged clavicles, interspinous bones, and vertebrse which 

 were named Platax Woodwardi by Agassiz (Poissons Fossiles, Vol. 

 IV, p. 250, Plate 19., figs. 3, 8, 1842-4), as well as the so-called 

 "Butterfly bones" figured by S. W'oodward (Geol. Norfolk, Plate 

 iii., figs. 31-33, 1833), which are generally referred to the same 

 species,_ are very abundant in the upper beds of the Crag. They 

 occur in the Forest-bed (Mem. Geol. Surv., Vert. Forest Bed,
