subacute; on the right side the 2"^ and y^ lobe are equal, twice as long as the anterior, both 

 are obtuse and the outer margin of the 2°'i is straight, though showing a small granule at the 

 posterior fourth; on the left side the outer margin of the 2"'' lobe is deeply and angularly 

 notched, so that this moiety has an appearance different from the right side. Just outside the 

 anterior tubercle of the posterior moiety of the subdorsal crest a small granule is observed and 

 another small granule occurs outside of the posterior end of this crest, for the rest the surface 

 is quite smooth between the posterior moieties of the subdorsal and dorso-lateral crests. The 

 anterior of the two teeth into which the anterior half of the 4"^ or lateral carina is divided, is 

 acute, the posterior rather blunt; the anterior just projects beyond the orbital margin, reaching 

 as far forward as the margin between the orbital and the branchiostegal spine. The posterior 

 moiety of the lateral crest is obsoletely notched at the posterior third, its anterior extremity is 

 obtuse and in front of it at the inner side a blunt tubercle is observed just above the outer 

 extremity of the hepatic groove, but for the rest the surface is smooth between the posterior 

 moieties of the 3"^ and 4''^ carinae, excepting a small granule near the posterior border of the 

 carapace. Just below the posterior moiety of the lateral crest on the right side one, on the left 

 three small granules- or tubercles occur. 



The three first somites of the abdomen much resemble those of Glyph. (Plastocrangon) 

 caeca W.-Mas., as regards their form and tuberculation, but the 4"^, 5'^ and 6"^ are shorter 

 with regard to their width and their tuberculation is different. The median crest of the i*' tergum 

 is moderately prominent, rounded above and anteriorly, the two lateral teeth resemble the 

 median, but appear obtuse, not broadly rounded, when looked at from above; on each side of 

 the median tooth a small obtuse tooth occurs. On the posterior part of the 1*' tergum are 

 situated at either side 3 or 4 rounded small granules, of which the inner is distinctly larger 

 than the others. Pleuron of i*' somite with 2 tubercles near the anterior margin, of which the 

 lower is subacute, the upper obtuse; infero-anterior angle subacute. Median carina of 2"'' tergum 

 notched in tl-te middle, obtuse, little prominent; at either side of the anterior part 3 tubercles 

 are situated, of which the middle is the largest, the inner the smallest; at either side of the 

 posterior part two hardly prominent tubercles are found, of which the inner is larger than the 

 outer. On the pleuron of the 2'"^ somite 3 rounded tubercles are placed in a triangle between 

 the anterior border and the median swelling, the upper tubercle is a little larger than the two 

 lower placed abreast; antero-inferior angle rounded, postero-inferior angle sharp, median tooth 

 acute. Median crest of 3'''' tergum entire, the transverse furrow faint, not reaching to the crest; 

 as on the 2^^ also at either side of the anterior part of the 3"''^ tergum three tubercles are 

 placed, of which the middle is the largest and placed with the outer near the anterior transverse 

 furrow, while the inner is the smallest and situated near the faint posterior groove ; the tubercles 

 of the posterior part of this tergum are inconspicuous. There are no tubercles on the pleuron 

 of the 3'^'^ somite, but the median .swelling ends inferiorly in a small subacute tooth, that is 

 directed forward; the pleuron ends in two sharp teeth, of which the anterior is larger than the 

 small posterior. Posterior transverse groove of 4"' somite only there developed where the tergum 

 passes into the pleuron; median crest moderately prominent, obsoletely notched at the anterior 

 fifth and the larger remaining part longitudinally fluted; one rather indistinct tubercle is observed
