Dr. Henry Woodward — Cretaceous Crustacea, Denmark. 489 



Length (of the specimen in the diagram), 6 mm. ; breadth, 4 mm. 

 "The greatest breadth is just behind the middle. 



Rostrum triangular; its superior surface is concave, with three 

 or four sharp spines on each side, which are directed forwards 

 and diminish in size from before backwards. Anterior margin 

 narrow and a little elevated near the point. Lateral margin curved 

 somewhat outwards behind the centre, and provided anteriorly 

 with small pointed teeth which are directed forwards, and of which 

 the anterior one is a little larger than the rest. The occipital 

 sulcus and its branches are shallow. The surface of the carapace is 

 characterized by more or less well-marked cross-lines, of which the 

 two anterior ones are drawn out into a short point directed forwards 

 and the posterior ones run fi'om side to side. Between these, 

 as well as on the rostrum, the surface is more or less granulated. 

 Cardiac region more or less prominent, and in some specimens pro- 

 vided with a sulcus in front. 



This species varies in this respect, that the teeth on the rostrum 

 are sometimes fairly large, and sometimes are very minute, needle- 

 shaped, and nearly invisible. 



Regarding the carapace, G. strigifera shows a great similarity 

 with 6r. strigosa (found in the North Sea), and is perhaps a precursor 

 of this form. 



This species occurs abundantly both at Annetorp and Faxe.

This species is represented by two rather incomplete specimens, 

 preserved as casts, both from Faxe. The length of the specimen 

 figured in PI. XII, Fig. 8 is 7 mm., the breadth about 4-5 mm. 



The rostrum is narrow and triangular, its superior surface smooth 

 and slightly concave, the borders ai'e smooth and provided on each 

 side of the base with a tooth directed forwards. The anterior margin 

 of the rostrum is fairly well raised ; the lateral margin is curved 

 in front of and behind the antero-lateral branch of the occipital 

 furrow, but is otherwise straight with indistinct, blunt teeth. The 

 occipital furrow and its branches are well marked. The cross-lines 

 are elevated, and run posteriorly from side to side in a way peculiar 

 to this species. The cardiac region is not prominent. The gastric 

 region anteriorly is sharply distinguished i'rom the frontal region, 

 which is situated on a lower level ; in the centre it is provided 

 with a ridge which is continued on to the rostrum. On both sides of 

 this ridge, a little behind the front border, are four small prominences 

 arranged in a semicircle and diminishing in size outwards. 



This species exhibits, particularly in the form of its rostrum, 

 an interesting transitional form between the genera Galathea and 

 Munida. The triangular form of the rostrum and its superior
