 This species is closely allied to the preceding, but differs from it in the following 

 characters : — 



1. The median carina of the carapace is distinct in front of the small mid-dorsal 



pit, but the anterior bifurcated part is entirely absent. The lateral margins 

 are not angled in front of the rounded postero-lateral corners and the anterior 

 width is only about half the median length, including the rostrum (fig. 38). 



2 . The rostrum is as long as wide and its strongly convergent lateral margins meet in 



a narrow rounded apex. In its carination it resembles that of 5. laevis (fig. 38). 



3. The cornea of the eyes is set transversely on the stalk. The anterior margin 



of the ophthalmic somite is broadly convex and does not project as a pro- 

 minent lobe between the base of the eyestalks (fig. 38). 



4. The propodus of the raptorial claw does not possess a spine at the distal end 



of its inferior margin. The dactylus is armed with only five teeth including 

 the terminal one (fig. 39). 



5. The anterior lateral process of the fifth thoracic somite is broader and shorter, 



and the posterior process of this somite and the lateral margins of the two 

 succeeding somites are more broadly rounded. The lateral portions project 

 almost horizontally outwards and do not reach downwards as much as in the 

 preceding species ; this feature, taken in conjunction with the slightly greater 

 proportional length of the free thoracic somites, is responsible for the widely 

 different aspect of these parts in lateral view (cf. fig. 37 x ij and fig. 40 x 5). 



6. The following abdominal carinae end in spines : — 



Carinae. Abdominal somites. 



Submedian . . . . . . 5,6. 



Intermediate .. .. .. 4,5,6. 



Lateral .. .. .. .. 3, 4, 5, 6. 



Marginal . . . . . . 2, 3, 4, 5. 



7. On the telson there are five submedian denticles, ten to twelve intermediate 



and one lateral. There is no praelateral denticle. On the ventral surface there 

 is a sharp and long post-anal carina (fig. 41). 



8. There are eight or nine movable spines on the outer margin of the basal joint 



of the exopodite of the uropod. 



The mandibular palp, as in 5. laevis, is entirely missing. 



The unique example of 5. hieroglyphica is of a dark yellow colour and appears to 

 have been preserved in spirit for many years ; jet-black markings are, however, dis- 

 tinct and on the telson seem to be quite characteristic. The surface of the carapace 

 and abdomen is very sparsely covered with large black chromatophores which are 

 aggregated and sharply define the outer margins and median carina of the rostrum, 

 the anterior portion of the gastric groove and the posterior margin of the segments of
