Sub-genus Macrocypridina n. siib-gen. 



('tfpri4{in<i (part.). :i u ' " '' " i'\. 



Desciiplion: — Slit- 11: - The li)rin is somrw li;ii . ilioiifjii (Hiiy rather slightly, (iillcicnt in 

 thf inalo.s and tho females. — It i.s oval with ;i wfll developed posterior corner. The roslnil 

 incisur is coniparativelv small, moderately deep and rather narrow. \ear llie inner ed^e ol the 

 incisur there are two medial bristles situated clo.se to each other. Presumably with com- 

 parativelv weak calcification. The species belonging to this sub-genus are comparatively large. 



First antenna: — This is long, slender and eight-jointed. The sen.sory bristle of 

 the fifth joint has thirteen sensory filaments. The b- and c-bristles of the seventh joint have 

 a similar modification in the males as that described above p. 223 for the sub-genus Doloria. 

 The proximal filament of these two bristles, which is situated a short distance from the base 

 of the bristles, is. however, comparatively rather slightly metamorphosed; it is of moderate 

 stri'ugth. is onlv slightlv .swelled proximally and is not stronglv chitinized and spine-shaped 

 distallv. but more hyaline and ending in a short and very fine (sensory?) hair like most of the 

 filaments on the bristles of the two distal joints of this antenna. The f- and g-bristles of the 

 end joint are very much lengthened, being considerably longer than those of the females. 



Second antenna: — The p r o t o p o d i t e has a medial-distal bristle. E x o- 

 p o d i t e: The bristle of the second joint is reduced. The natatory bristles of the third to the 

 ninth joints have no trace of spines. The third to the ninth joints have basal spines. The 

 e n d o p o d i t e is similar in the males and females, more or less strongly reduced, often with 

 a reduced number of joints. The distal (sensory?) bristle of the end joint is very long. 



Mandible: — P r o t o ]) o d i t e: The endite on the coxale is weakly bifurcated 

 distallv; its spines are arranged in distinct groups, those situated medially and distally being 

 rather powerful. This joint has no bristles except for the small one on the endite. 

 Basale: Of the ventral bristles one d-bristle is very long and has numerous long secondary bristles 

 and short hairs distally, the rest are of moderate length or short and have short, fine hairs or 

 are bare. This joint has three dorsal bristles. Endopodite: The first joint has four bristles 

 ventrallv. The end joint has seven bristles, of which one of the anterior ones is long and powerfiil, 

 claw-shaped, the rest being relatively short. 



Maxilla: — Protopodite: Dorso-distally the coxale has a single bristle with 

 long, fine hairs. Proximally on the outside of the third endite there is a single bristle. On the 

 boundary between the basale and the first endopodite joint there are three bristles, one close 

 to the exopodite, one at about the middle of the inside of the endopodite and one on the anterior 

 edge of the endopodite. Dorso-distally on the coxale there is a rather large lamelliform e p i- 

 podial appendage. The exopodite is relatively well developed, has long, fine 

 hairs, situated close together, and is not displaced distally. The endopodite is relatively 

 short and very broad.

 to Cypridtnifnrnies. This suffix may be reserved for real C y p r i d s.
