140 HALIPORUS SIBOGAE. 



antenna! scales; carpus sometimes distinctly shorter than 

 the merus, sometimes both joints are of subequal or equal 

 length ; dactyli as in the 4th legs, little more than half 

 as long as the propodite. 



Petasma longitudinally folded. The sternum of the last 

 thoracic somite arises, in the female, as a low, obtuse 

 tubercle, which is sometimes obscurely carinate longitu- 

 dinally. 



Branchial formula as in Haliporus, but there is a sm-all 

 arthrobranchia on the 7'^ somite. Minute, quite rudimen- 

 tary, exopods on all the thoracic legs and on the 2"'^ and 

 Srd maxillipeds. 



Length of male 165™™, of female 175™™-.

Closely resembling Halip. aequalis Sp. Bate. Rostrum 

 obliquely ascending both in the male and in the female, 

 straight, reaching to the far end of the 2f"l joint of the 

 antenuular peduncle, with 4 — 6 teeth on the upper mar- 

 gin in addition to 2 epigastric ones. Postrostral carina 

 distinct till near the posterior margin, though not at all 

 prominent, not interrupted by the cervical groove. The 

 four spines and the grooves on the sides of the carapace 

 arranged as in Halip. aequalis. Abdomen with the 3'"d — 

 6tli somite carinate, usually also the 1»^ and the 2^^, the 

 carina of the l^t being short and, like that of the 2°^, 

 little prominent; carina of the Q^^ somite ending in a tooth. 



As regards the eyes, the two pairs of antennae and the 

 thoracic appendages, this species closely agrees with Halip. 

 aequalis. Proximal joint of mandibular palpi comparatively 

 less broad than in this species. The two lobes of the petasma
