496 Dr. Henry Woodioard — Cretaceous Crustacea, Denmark. 



This species is very variable in form, but the following characters 

 seem to be fairly constant : — 



The circumference is more or less elliptical; the ratio between the 

 length and the breadth is generally as 1 : 1-2; the arching often 

 less than in the preceding species, particularly across the posterior 

 part. The size varies from 5 to 20 mm. in breadth. The lateral 

 margins are provided with small, often indistinct teeth, 7-8 ia 

 number. The lateral furrow is shallow, but distinct, being defined 

 behind by a small raised border which is generally noticeable even 

 behind the cardiac region. The posterior part of the mesogastric 

 region and the epigastric lobes is well marked and elevated ; the 

 last-mentioned are elliptical and situated transversely. The limit 

 anteriorly being often indistinct. On some specimens the anterior 

 angle seems to run out into a fine line, which ends in a small 

 tubercle. 



Of this species two types can be distinguished. One of these 

 particularly is more arched posteriorly, and a little broader than 

 long, with the largest breadth a little in front of the middle of the 

 carapace. The posterior margin is short, strongly curved, and 

 nearly smooth. The second type is broader, with its greatest 

 breadth over the middle. The posterior margin is long and 

 faintly curved ; it is more or less granulated, the granules being 

 small, thinly and irregularly scattered. Both types, however, 

 pass by many intermediate forms into each other, and seem to 

 appear just as frequently, and thus it is impossible to distinguish 

 between a typical specimen and its variety. 



D. elegans is fairly common at Faxe, and still more so at 

 Annetorp. This species appears also in Maestrichtien superieur at 

 Mont de Saint-Pierre and at Ciply.'

Larger, more strongly and evenly arched than the preceding 

 species. Circumference rounded. The size varies between 25 and 

 42 mm. The rostrum is broad, triangular, with its borders strongly 

 raised. The orbits are deep. The external angle of the orbit is 

 interrupted by a broad incision which runs outwards into a wide 

 sulcus. The external tooth of the inferior orbital border is 

 considerably larger than the inner one. The antero-lateral margin 

 begins a little below the inferior orbital border, and its teeth are 

 generally confluent, forming a sharp ridge which is divided by the 

 occipital furrow ; both serrations are pointed anteriorly and blunt 

 posteriorly. The posterior margin is somewhat curved inwards. 

 Both the occipital furrow and the lateral furrow are shallow ; the 

 last-mentioned is broad, defined behind by a sharp crest, which is
