End claw very powerful, about as long as the anterior side of the second endopodite 

 joint, smooth. 



M a X i 1 1 a (fig. 6): — P r o t o p o d i t e: The distal endite is armed with three bristles, 

 the middle one of which is usually somewhat shorter than the other two. The dorso-proximal 

 bristle is moderately long. The ventral bristles on the basale vary both with regard to number 

 and position not only fi'om one individual to another but even on the right and left maxillae 

 of the same specimen; from four to seven of these bristles were observed; of moderate and 

 somewhat varying lengths. In addition the basale has three subequal and rather short 

 dorso-distal bristles. The short ventero-distal bristle of this joint is developed. Endo- 

 podite: The posterior distal bristle of the first joint is somewhat shorter than the bristle 

 on the end joint. 



Sixth limb — The posterior edge is rather well rounded, the posterior 

 ventral corner is rather broadly rounded. There are 22 — 24 postero-ventral bristles and 

 five or six antero-ventral bristles. On the anterior edge only one bristle, the upper one, 

 is developed. 



Seventh limb (figs. 11 — 13): — This is armed with 22 — 26 cleaning bristles 

 of moderate and somewhat different lengths, scattered fairly regularly along the distal 

 part of the limb. The number and position of these bristles vary both from one individual 

 to another and from the right to the left limb of the same individual. Each cleaning 

 bristle has from three to five bells. Each end comb consists of 17—19 teeth. All these 

 teeth are of the same type, closely and evenly pectinated; they are strengthened distally; 

 cf. fig. 13. 



F u r c a: — This has eight or nine claws; of the three specimens investigated two had 

 nine, the third, the type-specimen, had only eight, one of its secondary claws was absent, but 

 I could not decide if the specimen in question was defective, which is, however, not improbable. 

 Of these claws the six or seven anterior ones are to be denoted as main claws. The first and second 

 main claws have no ventral basal teeth. One or two of the posterior secondary claws are 

 annulated. 



The lateral eyes are well developed. The m e d i a u e y e is smooth. 



The m a 1 e is unknown.
