inside (cf. C//. nhyssalis). Tlie niaxillnlac lia\-e in addition to tlie 4 Sp. on the posterior surface of I.i i 

 a short S 15; the Le 2 has 5 setae, tlie Li 3 lias 4 setae and the Bas]). Ill lias 5 setae; the endopodite 

 has 3 setae in Ri I, 5 setae in Ri II and 7 setae in Ri III. The exopodite has 10 setae of about equal 

 length, and the Le has 2 short proximal setae and 7 long distal ones. The maxillae are scarcely dif- 

 ferent from those of C/i. abyssalis cf. PI. V fig. 5 c, and the maxillipcds have the third basipoditc 33 as 

 long as the endopodite and 

 1-6 as long as the two basal 

 segment.s. 



The first pair of legs 

 is very nincli like that of CIi. 

 abyssalis; the articular niein- 

 brane between Re I— II is com- 

 pletely wanting posteriorly 

 and onh' slightly developed 

 anteriorly; the Se of Re I 

 distinctly extends be\'ond the 

 end of preceding segment, 

 and so does Se of Re II. 

 The articulation between Ri 

 I — II in the second pair of 

 legs is wanting j^osteriorly, 

 but is marked b)- an indi- 

 stinct line anteriorly, and the 

 Se of Ri I is slightly marked 

 as seen in text-fig.; the arti- 

 culation between Re I and II 

 is almost wanting posteriorly; 

 the St. has 50 — 60 sliort teeth. 

 The Se of Ri I is well devel- 

 oped but without an acces- 

 sory tooth in the four/// pair 

 of legs, and the inner margin 

 of the second basipodite is completely smooth. The only difference between the male and female is 

 found in i\\Q Ji/l/i pair of legs in the male (text-fig. 41 k); this is distinctly different from the preceding- 

 species by the segmentation of the left exopodite and by the wanting terminal setae. The labriim etc. 

 is scarcely different from that of 67/. Streetsii (cf. text-fig. 38 a); along the transverse ridge which limits 

 the labrum in front about 10 rather delicate setae arc found. The oral snrfaee of the labrum tl'l. \T 

 fig. I a) is rather characteristic, though showing most similarity to that of Cli. Streetsii: the supporting 

 cliitinous framework is less developed. The Jirst group of the longitudinal series consists of numerous 

 short spinules; the seeoud group consists of a single longitudinal row of fairly long setae; the third
