498 Dr. Senry Woodicard — Cretaceous Crustacea, Denmark. 



Dbomiopsis Bielet^, H. Woodw., sp. nov. (PI. XII, Figs, la, 6.) 



Description. — Carapace broader than deep (16 mm. broad and 

 12 mm. deep) ; antero - lateral border slightly concave ; frontal 

 margin prominent, with a central depression. Lateral margins 

 rounded ; postero-lateral margin sloping inwards ; posterior margin 

 (8 mm.) broad and nearly straight ; surface sparsely granulated, but 

 generally smooth ; with the exception of the epigastric prominences, 

 and the posterior margin of the mesogastric region, the lobes of the 

 carapace are generally very obscurely defined ; the cervical furrow 

 (Sc.) is most distinct and is very slightly curved ; the lateral furrow 

 {SI.) is faintly rugose, but less distinct than the cervical furrow ; 

 at the base of the mesogastric lobe is a short granulated band in 

 front of the cervical furrow, and two small pointed prominences 

 (divided by the median furrow), the points directed backwards, each 

 being marked by a minute tubercle ; the cardiac region is depressed 

 and only faintly outlined, its surface being marked by three small 

 equidistant tubercles, two in front and one behind ; four small 

 tubercles mark the border of the antero-branchial lobe, and three 

 the antero-lateral border. The two rounded prominences near the 

 anterior border of the epigastric lobes are very distinct. The 

 rostrum, which is rounded, is bent downwards between the orbits, 

 and is deeply indented by the frontal furrow. The orbits are 

 elongated transversely, and are open internally towards the rostrum. 



Remarks. — Two apparently full-sized specimens of this well- 

 marked species (16 x 12 mm.) are in Miss Birley's collection, also 

 one young specimen measuring 9 mm. in breadth by 6 mm. in depth ; 

 all three are preserved in hard compact limestone, which contains 

 also traces of the limbs. The species is distinguished by its well- 

 marked form, being broader in proportion to its depth than D. rugosa, 

 although specifically they are no doubt nearly related. The rostral 

 and frontal border is less prominent in Z>. Birleyce, and the posterior 

 margin is wider and straighter than in D. rugosa. All three 

 examples have been decorticated. 



I dedicate this species to my friend Miss Caroline Birley, who 

 has given so much time and attention to the study of geology and 

 paleontology both at home and abroad, and whose private collection 

 bears testimony to her devotion to science. 



Formation and Locality. — Hard Upper Cretaceous Limestone 

 (Danian) of Faxe : coll. Miss Birley. 



Dbomiopsis Copland^, H, Woodw., sp. nov. (PI. XII, Figs. 2a, b.) 

 Description. — Carapace slightly broader than deep (9 X 7mm.) ; 

 anterior border semicircular ; frontal region broad, depressed ; 

 orbits large, prominent, visible from above, and placed somewhat 

 diagonally ; enclosed externally, but open towards rostrum ; postero- 

 lateral margins contracting rapidly towards the posterior margin, 

 which is narrow, only 3 mm. wide, and emarginate. Cervical furrow 

 distinct; lateral furrow faint, but more strongly marked on the 

 margin of carapace ; antero-lateral margin very bluntly dentated or 

 undulated ; mesogastric and epigastric lobes slightly prominent ; 

 carapace generally smoothly rounded and lobes obscure.
