422 Davis — On the Fossil Fish of the Cretaceous Formations of Scandinavia. 



0-035 m. behind tlie occiput, and is 0-025 m. in length. The vertebrae are 

 0-005 m. in length, and a little less high than long. 



The specimen represented by fig. 4 is in all probability a smaller example of 

 the same species. A number of spinous rays are preserved on the dorsal surface. 

 The anterior ray is located a distance behind the occiput, equal to the length of 

 the head. The fin-rays are supported by inter-spinous bones. The ribs are long 

 and moderately strong. A series of epiplural spines extend transversly to the 

 ribs, parallel with, but separated a short distance from, the vertebral column. 



This species does not agree with any of those previously described, as far as 

 its imperfect remains can be deciphered.

Genus. Berycopsis. Dixon. 



This genus was proposed by Professor L. Agassiz for a fish from the Chalk of 

 Sussex. It has much resemblance to the genus Beryx, but difPers from it in the 

 absence of pectinations on the free margins of the scales. The scales are of 

 moderate size, thick, and smooth, or only ornamented with delicate radiating 

 lines. The fin-rays of the dorsal and anal fins are robust. The rays of the 

 dorsal fin are continuous with the preceding spinous rays, six or more in number, 

 shorter than the soft rays, but stout and strong. Pelvic fin with a spinous ray, 

 and seven or more articulated rays. Anal and caudal fins unknown. 



The only species known is B. elegans, Dixon, from the middle chalk, Clayton, 

 of which the type specimen is in the Brighton Museum. There are others in 

 the Natural History Department of the British Museum, South Ken sington. 



Berycopsis lindstroni, Davis. 



(PI. XLiv., figs. 1, la.) 



A large and unique specimen, which apparently belongs to this genus, occurs 

 in the collection of the Geological Survey at Stockholm. The length of the part 

 preserved is 0-23 m. ; but the fish is devoid of the caudal fin, and the head is 

 somewhat dislocated, and badly preserved. The body is deep, measuring 0-10 m. 

 in front of the dorsal fin. The dorsal and anal fins are not preserved, except the 

 remains of a single spinous ray of the dorsal ; but the pi'esence of a long dorsal fin 

 is indicated by a long series of inter-spinous rays, which, no doubt, afforded
