The eyes are comparatively large, ovate, placed at the base of the first pair of 

 antennfe. They consist of more than thirty ocelli each. 



The jirst pair of antennce (Pl. V, fio-. 15 and 16) are long, loiiger than the head 

 and the first pereional segment together. The first joint of the peduncle is almost as 

 long as the two following joints together. The first joint of the flagellnm is high and thick, 

 not twice as long as the peduncle, the margins are smooth; the three folloving joints are 

 comparatively large, the last one rounded, almost turaid, longer than the two preceding 

 joints. The first three joints carr}- long hairs and olfactory säcks; the last joint carries 

 only two simple hairs. 



The second pair of antennas (Pl. V, fig. 17) are comparatively short, reaching only 

 beyond the posterior margin of the second pereional segment. The second joint of the 

 peduncle is a little longer than the first, the third joint is more than twice longer than 

 the two preceding together; the iirst joint of the fiagellum is much longer than the last 

 peduncular joint, tapering towards the end; it is fringed with very short hairs along the 

 upper and inferior margins. After it follows onlv one minute joint, tipped with one 

 very long and two shorter hairs. 



The pereion; the iirst segment is longer than lhe seventh (5:7), the second and 

 third are the longest. The last three pereional segments are much longer than the fourth 

 (10:7). All the legs are more robust than in Lanceola Lovmi. 



The epimerals are longer than in the next preceding species. 



The hranchial säcks as in Lanceola Lovéni. 



The first pair of pereiopoda {F\. V, fig. 18); the tihial process is long, tipped with 

 long bristles; the carpus is much longer than broad (11:18), the lower margin feebly 

 excavated. The metacarpus is longer than the lower margin of the carpus. The 

 dactylus is feebly curved, half as long as the metacarpus. 



The second pair; the carpus is ovate, longer and thicker than the metacarpus. 

 The dactylus is feebly curved, longer than a third of the metacarpus. 



The third and fourth pairs; the fenuir is elongate-ovate; the metacarpus is shorter 

 than the carpus. 



The fifth pair (Pl. ^^ tig. 19) are as long as the foui'th; the femui- ii:n'i'ow, linear; 

 the tibia is long; the metacarpus is a little longer tlian the carpus. The dactylus is 

 smooth. 



The sirth pair (Pl. V, fig. 20) are shorter than the pereion (11 : 12); the metacarpus 

 is a fifth longer than the carpus. The dactylus is serrated. 



The seventJt pair (Pl. V, fig. 21) are a fourth shorter than the foui'th pair and 

 longer than lialf the sixth. The dact-\lus is finely serrated along the concave margin. 



The pleon is as long as the last three pei-eional segments or longer. The lateral 

 parts of the segments are deep, evenly i-ounded below. 



The pleopoda (Pl. V, fig. 22) with the rami 12 to l,')-jointed. 



The urtcs without the telson is longer than the last pleonal segment; the second 

 and third segments are coalesced into one, much longer than the first. 



The iiropoda (Pl. V, fig. 23) are comparatively short; the peduncles of the first 

 two pairs are finelv serrated along the outei' margin, fringed Avith equidistant hairs
