edge. Dorso-distally on tlie coxale there is a rather large lamelliform c p i p o dial a p p e n- 

 d a g e. The e x o p o d i t e is comparative^ well developed, with close, fine, long hairs; 

 it is not displaced distally. The endopodite is broad and moderately long. 



Sixth limb: — The second exopodite joint is rather short and somewhat 

 rounded with numerous bristles: its posterior-distal bristles are not strikingly large in comparison 

 with the other bristles. 



Seventh limb: — This has rather numerous cleaning bristles, of which a rather 

 large number are situated ver}' close to each other distally, the rest scattered irregularly along 

 the distal part of the limb. With regard to the position of these latter bristles it is to be noted 

 that on the same side of the same joint there is only extremely seldom more than one bristle. 

 The end comb consists of a moderate number of rather powerful teeth, some rather long, distally 

 rounded distal teeth, smooth except that at the middle they have a small secondary spine on 

 each side, and decreasing somewhat in length the more proximally they are situated, some 

 rather shorter and broader, quite bare proximal teeth rather sharply cut off distally. Dorsally 

 close to the end comb tlie wall of the limb is rather strongly thickened and also rather deeply 

 concave. The ventral part of the wall in this notch is continued proximally as a peg of 

 chitin with which the chitinous part that forms the dorsal wall of the notch is moveably joined; 

 this latter chitinous part ends dorsally in a freely projecting, rather powerful little verruca. 

 The ventral and the dorsal walls of this notch may be pressed together somewhat like a jaw, 

 when the distal teeth of the end comb are also pressed in towards the dorsal edge of the notch; 

 this compression is carried out by a short, powerful, paired muscle, issuing somewhat proximo- 

 dorsally of the point of the limb and fixed to the bottom of the notch, both to the ventral 

 and the dorsal chitinous hinge. This muscle seems to be a specialized part of the anterior 

 longitudinal muscle of the limb. 



Furca: — The lamellae are moderately elongated; the number of claws is about 

 eleven; there is no clear division into main claws and secondary claws. 



Upper lip: — This has no large processes and is only slightly divided into fields; 

 one can distinguish one anterior upper unpaired field of glands, the openings of which are directed 

 anteriorly-ventrally and two posterior-ventral fields with the openings of the glands directed 

 ventrally; these glandular fields are divided from each other only by shallow grooves. There 

 is an unpaired protuberance on the front between the upper lip and the rod-shaped organ. 



The median eye is well developed and is of ordinary size and type. The r o d - 

 s h a p d o r g a n is fairly well developed and rather short and thick. 



The lateral e y e s are well developed. 



Xiimhrr oj sprrii-s. Remarks: — As far as I know this sub-genus comprises only the two species described 



l)elow. Possibly one or more additional representatives of it may be iound among the rather 

 numerous species of this sub-family that have been dealt with in the literature; on account of 

 the incompleteness of the descriptions nothing can, however, be stated with certainty about this. 



iMntini, h'uvccn ihr With regard to the relation between the two species I will only point out here that the 



s/irrirs. form ('. fD.) loris found nt S o u t h (\ e o r g i a is certainly to be regarded as more divergent
