the micldle line. Four foUowing somites iudistinctly and obtusely 

 carinate in the middle line, the carinae not at all prominent, but 

 each tergum presenting a regular, symmetrical and arborescent 

 figure. Calcified anterior part of the telson ending posteriorly in 

 four sharp spines. 



Proximal (outer) squame of outer antennae with two sharp teeth 

 as in A. Haanii Berthold; inner border with five sharp teeth, 

 the first cousiderably larger than the foUowing. 



Sternum less broad, less concave, first sternal joint flattened, 

 not hollowed out. 



Thoracic legs stouter, less slender than those of A. Martensii, 

 with longitudinal grooves on their outer surface, except on the 

 Ist pair; propodites of the 3rd legs distinctly compressed, S^j.^- 

 times as long as their average breadth. 



Length of the single female, that was collected, 25,5 m.m. 



5. Axius (Neaxius?) euryrhynclius n. sp. 



Station 86. Anchorage off Dongala, Palos-bay, Celebes. 

 Depth 36 M. 



Rostrum broad, flattened, carinate in the middle line, slightly 

 inclined downwards, reaching almost to the distal end of the 2nd 

 joint of the antennular peduncle ; at the level of the short, distinctly 

 facetted and pigmented corneae the rostrum is a little constricted; 

 the rounded, anterior border is notched in the middle and armed, 

 on either side of this notch, with 7 or 8 upstanding teeth. The 

 lateral margins are continued backward as carinate ridges until 

 the middle of the gastric region. 



Abdomen not yet once and a half as long as the carapace. 

 Telson with a pointed tooth in the middle of its posterior mar- 

 gin, appearing without this tooth just as broad as long, no spi- 

 nules on its upper surface. Caudal swimmerets as long as telson, 

 exopodite obovate, once and a half as long as broad, the anterior 

 and apical border beset with 19 small, sharp teeth. 



Third joint of antennular peduncle twice as long as thick, a 

 little longer than the 2nd; outer flagellum 2 — 3 times as thick
