Cmstacean Fauna of South Africa. 151 



Secoiid antenna nearly as long as 1st, slender, ultimate peduncular 

 joint shorter than penultimate, flagellum half as long as ultimate 

 peduncular joint, 4-joiuted. 



Mandibular palp rather long, slender, 3rd joint a little longer than 

 1st, not quite half length of 2nd. 



The other mouth parts without particular features. 



First gnathopod, interior margin of the process of 5th joint quite 

 smooth, 6th joint slightly tapering distally, inner margin finely 

 denticulate, finger more than ^, in g nearly ^, length of 6th. 



Second gnathopod, 5th joint ending obtusely, 6th elongate-oval 

 (similar to that of L. lilljeborgii Boeck), palm convex, denticulate only 

 on its distal half, palm and hind margin in the largest specimen 

 feebly differentiated, finger strongly curved. 



Third to fifth peraeopods, posterior margin of 2nd joint entii-e, or 

 very obscurely serrate, other joints moderately spinose, anterior margin 

 of 6th joint with a very regular and even row of spiuules. 



First and second uropods feebly spinose ; third uropods lost. 



Length : <$ from Cape St. Francis 9 mm., from Grlendower 

 Beacon 14 mm. ; ovigerous 5 8 mm. 



Colour : In spirit, yellowish or pale pinkish, eyes light red-brown ; 

 in life, flesh-pink, eyes crimson.

Geogr. Distribution : Mediterranean (Lessona, Delia Valle, Chevreux). 



The depth of the sinus on postero-inferior angle of 3rd pleon 

 segment varies somewhat ; it is strongest in the two male specimens, 

 and in one of the females is very feebly developed. 



LEUCOTHOE DOLICHOCERAS n. sp. 

 (Plate XXVI. Fig. 14.) 



Antero-lateral angles of head rounded. Eyes not distinguishable. 

 Side-plate 1 slightly widened below, 2, 3, and 4 deeper than long, 4 

 deepest at the blunt antero- inferior angle, thence sloping evenly and 

 without any angle backwards 'and upwards to emargiuatiou. Postero- 

 inferior angles of 2nd and 3rd pleon segments acutely produced, 3rd 

 with deep sinus above. 



Telson twice as long as broad, oval, apex broadly rounded.
