Leander semmelinkii n. sp. and many other species of Ca- 

 ridae on the road of Macassar (Celebes), Januari 1880. 

 This new form is closely allied to and has the size of 

 Leander distans Heller, but is distinguished by the num- 

 ber of teeth of the rostrum and by the second pair of legs. 

 Rostrum lanceolate, reaching to the end of the anten- 

 nal scales , upper margin straight or a little convex , as 

 also the under margin , which is not emarginate at the base ; 



it is —3 — — dentate , the teeth of the upper margin acute 



directed forwards, extending along the whole margin , distance 

 between the two first twice as large as between the others , the 

 third tooth situated above the eyes , the three or four teeth of 

 the under margin situated in the middle of it , minute and 

 hidden by the hairs of the margin. Carapace smooth , 

 branchiostegal spine small , a little remote from the mar- 

 gin , abdomen as in Leander semmelinkii. Peduncles of 

 the internal antennae a little shorter than the antennal 

 scales , short filament of these antennae connected only for a 

 short end with the long filament. External maxillipeds 

 reaching to the second joint of the peduncle of the upper 

 anteunae. First pair of legs reaching with the hand beyond 

 the end of the antennal scales , the carpus being nearly 

 twice as long as the hands. Second pair of legs very 

 elongate , stronger than the first pair , reaching with the 

 greater distal half of the wrist beyond the antennal scale ; 

 wrist a little shorter than the hand , much longer than 

 the palm, fingers very thin, closely situated to one another, 

 and very slightly longer than the palm. The other am- 

 bulatory legs very thin , quite unarmed , with the claws 

 very elongate and nearly straight, those of the last pair 

 extending with half the tarsus beyond the antennal scale. 

 Length from the tip of rostrum to the end of the ab- 

 domen 25 mm. 



Length of the legs of the second pair 16 mm., length 

 of the wrist 8^/3 mm., of the whole hand 4^/2 mm., of 

 the fingers 2^/3 ï^"^-
