Eemarks. — This is a very well-marked glabrous form and quite 

 distinct in outline from any of the other species ; the sides being 

 narrower and contracting posteriorly, and more rounded and 

 depressed in front ; with the orbits visible from above, which is 

 not the case in any other species of Dromiopsis. 



Among the smaller specimens of Dromioims I have detected 

 a minute, very round, smooth form ; the carapace is 6 mm. broad 

 and 5 mm. deep ; it agrees generally with the larger example 

 (Figs. 2«, h). The cardiac region in this small specimen is more 

 clearly defined, and has three equidistant tubercles on its surface; 

 the orbits are large and prominent, and the outline of the back is 

 very globular ; this latter character is probably due to its being 

 a young individual. 



I dedicate this species to Miss Copland, who participated with 

 Miss Birley in her geological labours and collected many of the 

 specimens with her own hands at Faxe.

K. 0. Segerberg obtained several specimens of this species both 

 from Annetorp and Faxe, preserved as casts, nearly all, curiously 

 enough, without frontal or lateral margins being preserved (cf. 

 Carter, Decapod. Crust., p. 22). 



Anteriorly depressed, otherwise nearly even ; the length about 

 22 mm. (on the larger, figured specimen). Rostrum narrow, 

 triangular, and depressed, provided with a small tubercle on each 

 side. Lateral and posterior margins long, straight, elevated into 

 a ridge. Occipital furrow deep and broad at the sides, narrower 

 between the mesogastric and the urogastric lobes, and having two 

 pointed elevations in the centre. Lateral furrow narrow, faintly 

 defined ; nearly straight on each side of the middle line ; directed 

 outwards and forwards. The different regions are all very 

 conspicuous and limited by deep sulci. The epigastric lobes are 

 marked by two distinct tubercles. One sees three other similar 

 tubercles on the protogastric lobes. The mesogastric lobe is well 

 defined on all sides. The urogastric lobe is pointed at the sides. 

 The cardiac region is pentagonal and elevated. The antero- 

 branchial lobes are divided on the inner side into two parts, of which 

 the superior one is the shorter. The postero-branchial regions are 

 triangular and large ; there is a tubercle on the inner posterior part. 

 The superior surface is more or less thinly and irregularly granulated. 

 On a younger specimen (op. cit., pi. ii, fig. 7) similar granules can 

 be seen, particularly on the mesogastric and cardiac lobes. On an 

 older one (op. cit., pi. ii, fig. 6) one sees these granules both on the 

 cardiac and postero-branchial lobes arranged transversely in short 

 rows ; on account of this arrangement the casts have a somewhat 

 ridged appearance. Another old specimen, on the contrary (pi. ii, 

 fig. 8), has the posterior part nearly smooth, and the tubercles on
