KONGL. SV. VET. AKADEMIENS IIANDLINGAR. BAND 21. N:0 5. 35 



The pereion; the first segment is longer than the seventh, the fourth is much the 

 longest. 



The epimerals and branchial sacks as in Lanceola Sayana. 



The ovitectrices (PI. V, fig. 11) are much longer than the branchial sacks, broadly 

 dilated below, fringed with long equidistant hairs. 



The first pair of pereiopoda (PI. V, fig. 6); the carpus is triangular, as long as 

 broad. The metacarpus is more slender than in the preceding species, almost twice as 

 long as broad at the base, equalling in length the lower margin of the carpus; it is 

 fringed with short hairs. The dactyl us is slender, feebly curved, as long as half the 

 metacarpus. 



The second pair (PI. V, fig. 7); the tibial process is shorter than a fourth of the 

 carpus. The carpus and metacarpus are long with straight margins, the dactylus is 

 feebly curved. 



The third and fourth pairs are equal; the femur is long, linear; the tibia is longer 

 than the carpus; the carpus shorter than the narrow, elongated metacarpus. 



The fifth pair are longer than the fourth (7:6), and only a little shorter than the 

 sixth (35:41). The metacarpus is longer than the carpus. 



The sixth pair (PI. V, fig. 8) are longer than the pereion (41:35); the femur 

 is narrow, linear; the tibia longer than the carpus; these joints are coarsely but indistinctly 

 serrated along both margins, each tooth carrying a very short bristle. The metacarpus 

 is feebly curved, much longer than the carpus (5:3), and armed in the same way. The 

 oblique anterior margins of the terminal excavation are totally straight. The dactylus 

 is long, less curved than in the preceding species, armed along the concave anterior margin 

 with three or four long spines, between which there are many short ones. 



The seventh pair (PI. V, fig. 9 and 10) are a third shorter than the fourth pair, 

 and shorter than half the sixth; the anterior margins of all the joints are armed as in 

 the preceding pair. The dactylus is serrated along the concave margin. 



The pleon is a fourth shorter than the last three pereional segments. The dorsal 

 line is prominent and the hinder median corner of the segment projects into a sharp- 

 pointed tooth, the whole forming a serrated crest. The lateral parts of the segments are 

 evenly rounded below. 



The pleopoda (PI. V, fig. 12) are like those of the preceding species. 



The urus without the telson is as long as the last pleonal segment; the second and 

 third ural segments are coalesced into one, shorter than the first segment. The first seg- 

 ment shows a pointed dorsal tooth as in the pleonal segments. 



The uropoda (PI. V, fig. 13) are more elongated and narrow than in Lanceola Sayana; 

 the peduncles are smooth along the outer margins, and bordered with minute bristles along 

 the inner, the interior rami are serrated along both margins. 



The telson is elongate-lanceolate, pointed, shorter than the peduncle of the last pair 

 of uropoda.
