'Plic ('//r.v iii'(> ovate, ocenpying a littlc inovc thiui half the depth of the licad. 



T\\oprst pair nf antennce (Pl. IX, iig. 2) are <|uito as long as the head and the first t\v(j 

 pereional segments togethev. The first joint of the peduncle is as long as the two foUowing 

 joints together. The first joint of the ffagelliim is nK)re than twice as long as the pedunele. 



The second pair af antennce (Pl. IX, tig. ?>) are ten-jointed in the male and five- 

 jointed in the feraale; in the male the third joini of the peduncle is angnlarlv bent against the 

 preceding joint, a fäet whieh ])oints to the case of the Trypliamidce and following families. 



The pereion; the first segment is shorter than the second, the fifth is the; longest, 

 the seventh scarcely shorter. 



The epimcrais are rather small, those of the sixth pair are the deepest. 



The first pair of jierciojKula (Pl. IX, tig. 4) with the carpus broad, but not produeed 

 shorter than the raetacarpus. The metacarpus has the hindei- margin feebly concave, 

 finely seri'ated; the dactylus longer than half the raetaearpus, serrated. 



The second pair (Pl. IX, fig. 5); the tibial process is longer than half the carpus, tipped 

 with long thick bristles. The carpal process is as long as two thirds of the metacarpus, 

 narrowly spoon-sliaped, the margins serrated. The hinder margin oi the metacarpus 

 is straight, strongly serrated. The dactj^lus as in the preceding pair. 



The third anil fourlli 'pairs (Pl. IX, fig. 6) with the fem ur narrow, feebly bent. The 

 tibia is very large and thick, tumid, much broader and longer than the following carpus. 

 The metacarpus is very stout, finely serrated and spinous along the hinder margin. The 

 dactylus is very long, almost as long as the metacarpus, smooth. 



The fiftli and si-.rtlt pairs (Pl. IX, fig. 7 and 8) with the fem ur irregularly ovate, 

 provided with four to five short spines at the lower anterior coi'ner. The tibia is a little 

 longer than the carpus. The carpus of the sixth pair is provided with six long, equidi- 

 stant bristles. The metacarpus is scarcely a third longer than the carpus, finely serrated 

 along the anterior margin. The dactylus is somewhat shorter than the metacarpus. 



The s<'vni.tli pa,ir{^\. IX, fig. 9, 10 and 11); the fcmur is a fourth longer than broad, 

 a little longer than the thi-ee following joints. The dactylus is as long as two thirds of 

 the metacarpus. 



The pleon is a little shorter than the last ti\"e pereional segments; the inferior margins 

 of the segments ai-e a little excavated. 



The rami of the 2^ieopoda (Pl. IX, fig. 12) are fen- to twelve-jointed. 



The u)-us is as long as the last pleonal segment. The first segment is longer than 

 the two followino' tos'ether, the third is more than t^\'i(•(' lonoej- than the second. The hinder 

 corners of the last segment are feebly rounded. 



The uropoda (Pl. IX, fig. !?>). The exteriör rami are a little shorter than the inferior; 

 those of the first two pairs are fineh' serrated along both margins. The exteriör ramus of 

 the last pair is smooth on the outer, and finelv serrated on the inner margin; the interiör 

 ramus is smooth on the inner margin, and iinelv serrated on the outer: the peduncle 

 is longer than the last two ural segments. 



The trisoii is lono-er than the last lu-al seo-nienf.
