f)eraeopoda, and the numerons, red-brown, star-like pigment-spot.s on Xhn siiles of thc 



pent;onal segments. 



In 188-5 Cabits g&va the foWov/ing diagnosis in Latin: 



»Articulis basalia antenns ntrioäqae. labiDinqae snperiiLs aeoleia instmr-ta; i^iiri-:» -t-./uirn- 

 torum raaculis stellatis fuäco-mbriä: femora I et II angolatim curvata.x 



From rny own examination of fresh specimeas I give the following detaife: 



The female. 



The forepart of the hodi/ is thick, and inflated, the hind part is very narrow and 

 -lender. The head and perajon together are longer than the pleon and uras together. 



The head is broader above than below: the antennal groove commences above the 

 middle of the front side, and is long and narrow. The head is only a Kttle longer than 

 the first tvvo perseonal segments together, and is considerably broader than the peraeon. 



The first pair of antennm (PL AlV, fi^. 31) are longer than the head, but shorter 

 than the head and the first two perseonal segments together. The pedoncle consists of a 

 single joint; the inner lower comer is prodaced into a long, spine-like process, which is 

 considerably longer than the rest of the pedimcle. The single flageUar joint is maeh 

 longer than the pednncle with the process: it is broad at the base. thereafter more slender, 

 nearly cylindrical, and broadly rounded at the apex: on the sides there are a few short 

 projections tipped with hairs. 



The sec<ynd pair of antennee (PL XTV , tig. 32) are scareely longer than the stem 

 of the peduncle in the first pair. The first free joint of the pednncle is twice as broad 

 as loug; the second joint is more than three times as long as the first. tapering towards 

 the apex, and perfectly smooth; the single flagellar joint is elongate-conical, nearly as 

 long as the whole peduncle, and is tipped with a few short hairs. 



The motith-organs are like those in Pkronimop-s-is Sarsi; a tree-jointed mandibnlar 

 palp is present. 



The perceon is abont three times as long as the head, and is as long the whole pleon. 

 The first two segments are dorsallv coalesced, the second being m.ore than twice as long 

 as the first; the third and fourth are equal in length; the foUowing increase in length, 

 and show a very short spine-like projection dorsaUy in the median Hne. The epimerals 

 are fused with the segments. The perieon is, at the middle, more than fonr times as 

 broad as the pleon. 



The branchial ■sacLs are considerablv shorter than half the femora of the correspond- 

 ing pairs of perasopoda. 



The Jirst pair of -perceopoda. The femur is narrow, angularly bent, and as long- 

 as the three follo\ving joints together. The carpus is longer than the two preceding 

 joints together, and has the hind margin smooth. The metacarpus is scarcely longer 

 than the carpus, with a few short spines on the hind margin. The dactylus is hirsnte, 

 and like that in Phronimopsi^ Sarsi. 



The second pair are in shape esactly like that pair in Ph. Sars-i. but hare the meta- 

 carpus much larger; hanging straight down the second pair reach fnUy to the apex of
