PEOM THE INDO-PACIFIC AND WEST AFEICA. 303 



readies as far forward as tlie peduncle of the upper antennge, and that tlie palm is 21 mm. 

 broad looked at from above and 1"9 mm. in the middle measured on the outer side. 

 The fingers are already covered with the characteristic woolly pubescence. The left leg 

 is only 30 mm. long and almost quite smooth. The following legs are also smooth ; 

 those of the fifth pair reach to the end of the antennal scales. 



Eive of the eight females from the Congo Coast are provided with eggs ; the largest of 

 these five is 80 mm., the shortest 58 mm. long from the tip of the rostrum to the end of 

 the telson. The cephalothorax is smootli. The rostrum (fig. 18) agrees, in its general 

 characters and outer appearance, with that of the female from the River Prah and in all 

 it curves more or less upward at the distal end ; the teeth-formulae are given in the 

 Table. In all eight females 8, 9, or 10 teeth of the basal portion are separated bij a 

 smooth interspace from one or two, rarely three apical teeth, and these apical teeth are 

 either closely situated near each other or a little distant; two or three teeth are on the 

 carapace and the lower margin is armed with 4, 5, or 6 teeth. 



In the larger specimens the fingers of the first pair project beyond the antennal scales, 

 in the smallest one these legs are just as long as the scaphocerites. The legs of the 

 second pair agree with those of the female from the Hiver Prah. They are generally 

 equal, half as long or little more than half as long as the animal. In the largest female, 

 which is 80 mm. long, these legs project a fourth of their carpus beyond the antennal 

 scales ; in another (No. 7), which has almost the same size, the second legs (PL 18. fig. 19) 

 are just as long as the scaphocerites. In the former specimen the carpus is 12 mm. 

 long, and 1"5 mm. thick at the distal end, in the other these numbers are 10 mm. and 

 1"6 mm. ; so that the carpus of No. 5 appears somewhat slenderer than in the other. 

 In two females the carpus is a little shorter than the hands, but in the others these 

 joints have about the same length ; the fingers, which in all are covered loith a felt- 

 like pubescence, though the tips are generally devoid of it, are usually a little shorter 

 than the palm. The fingers carry ahout the same teeth as in the male, but they are 

 fewer in number and smaller. So, e. g., in the female (No. 6) the dactylus (figs. 20-22) 

 carries an obtuse tooth at one-third of its length from the articulation and behind it four 

 other teeth, which are also obtuse, a little smaller and of unequal size. The immobile 

 finger is also armed with an obtuse tooth at the end of its cutting-edge, and this edge is 

 a little longer than on the other finger ; between this tooth and the articulation are 

 seen six smaller teeth, also of unequal size. Looked at from above the joalm i)rcsents 

 the same breadth along its whole length, but viewed from the lateral side, jialm and 

 fingers slightly decrease in height or thickness and the fingers taper gradually towards 

 their tip. In the largest female (No. 5) the uppei- surface of the palm is 1'5 mm. broad, 

 but looked at from the outer side the palm ajjpcars 1"1 mm. thick at its proximal end, 

 1-3 in the middle, and I'l at the base of the fingers. Pine short hairs are distributed 

 on the joints, and as regards the distribution and size of the small spiuules on their inner 

 and lower surface, these Congo specimens fully agree with the female from the Iliver 

 Prah. So, e. g., the spinules on the inner margin of the carpus of tlie leg figured 

 (fig. 20) are rather slender and 0'25-0-27 mm. long (fig. 21) ; similar spinules occur 

 on the inner margin of the palm ; those on the inner margin of the merus are, however.
