FROM THE INDO-PACIFIC AND WEST AFRICA. 313 



left. The palm of the right leg is 35 mm. broad and 3 mm. thick in the middle ; the carpus, 

 which has a length of lO'S mm., is 36 mm. thick at the distal end, so that in this specimen 

 the j)alm appears not broader than the carpus. The dactylus carries Jive small teeth of 

 equal size between the tooth at the end of the cutting-edge and the articulation ; on the 

 index, however, only one obtuse tooth is seen behind that at the extremity of the cutting- 

 edge. All these teeth are very small and of equal size, so that the fingers shut close 

 together. This specimen is evidently an individual variety, in the same way as 

 PalcBtnon vacjus. Heller, is a variety of the well-known Indian P. lar. 



In the male No. 12 the rostrum fally resembles that of the male No. 8 described 

 above ; it reaches to the end of the scales, but there are only 11 teeth on the upper 

 and 3 on the lower margin ; three teeth stand on the cephalothorax. The outer foot- 

 jaws project for four-fifths of their terminal joint beyond the peduncles of the lower 

 antennae. The carpus of the first legs is 7 mm. long, and projects for two-fifths of its 

 length beyond the distal end of the scales ; the hand, 3*75 mm. long, is little more than 

 half as long as the carpus, and fingers and palm have the same length. The left leg of 

 the second pair is the larger, projecting for a third of the carpus beyond the scapho- 

 cerites. The merus is distinctly longer than the carpvis and 1-4 mm. thick at the distal 

 end ; the carpus is 18 mm. thick at its distal extremity. The palm is 2-25 mm. broad 

 and 1*8 mm. tliick in the middle. 



In the quite young male (No. 16) the rostrum (PI. 20. fig. 46) reaches, as in most young 

 individuals, to the end of the scales, and four teeth stand on the cephalothorax. The 

 outer footjaws project for three-fifths of their terminal joint beyond the peduncles of 

 the external antennae. The carpus of the legs of the first pair, 5"3 mm. long, extends 

 for one-fifth of its length beyond the scaphocerites ; and the hand, 3 mm. long, is again 

 a little more than half as long as the wrist. The larger leg of the second pair is the left 

 one (PL 19. fig. 47); the carpus extends for a fourth of its length beyond the scales ; 

 the merus is 8 mm., the carpus 116 mm. thick, at theu* distal extremities. The palm is 

 1-42 mm. broad and 1"31 mm. thick in the middle. The immobile finger (PL 20. fig. 48) 

 bears one, the dactylus two obtuse teeth between the conical tooth at the end of the 

 cutting-edge and the articulation. The legs of the third pair reach to the end of the 

 scales, the two following are somewhat shorter. 



In the largest female but one from Catumbella, 84 mm. long, which bears no eggs, the 

 rostrum (fig. 49) reaches midway between the distal end of the antenuulary peduncles 

 and that of the scales. It fully resembles that of the preceding specimens from the same 

 locality : the fifth tooth stands just above the orbital margin, the upper margin is sliglitly 

 convex above the eyes and the tip is somewhat turned upwards ; the tliird tooth of the 

 lower margin reaches to the middle of the terminal joint of the antennulary pedimeles. 

 The outer footjaws extend almost for the whole terminal joint beyond the extremity 

 of the peduncles of the outer anteuuic. The carpus of the first legs is 13 mm. long, and 

 projects for half its length beyond the antennal scales ; the hand is 7 mm. long. The 

 left leg (fig. 50) of the second pair is considerably larger than the right (fig. 51). The 

 merus is 3 mm., the carpus 34 mm. thick, at their distal ends, and the latter projects 

 for half its length beyond the end of the scales; the palm, slightly longer than the
