more than half as long as the animal, aud project beyond the distal end of the scales by a 

 third part of their carpus. The chelae are also slender and somewhat shorter than the 

 preceding joint ; the fingers, already slightly pubescent, are a little shorter than tlie palm. 

 The palm is 1 mm. broad above, and its breadth remains the same along its whole length, 

 but it narrows slightly towards the base of the fingers when the lateral side is looked at ; 

 the palm is 075 mm. high in the middle, so that it is but slightly compressed, namely in 

 the proportion of 4 : 3. The second legs are nearly smooth and the fingers are marked 

 with small red spots. The third aud fourtli legs reach almost to the end of the scales. 



In younger females, which are 35 mm. long, the first legs reach as far forward as the 

 lateral terminal spine of the scales ; the second legs, half as long as the animal, project 

 with only their chelae beyond the distal end of the scales. This is also the case in still 

 younger individuals, though sometimes the wa-ist projects a little beyond the scales. 

 Now it should be remarked that the carpus of the second legs has generally in these 

 younger specimens from Catumbella a somewhat slenderer form than in the older 

 individuals from the Congo Coast, as will be found by comparing in the Table the 

 proportion between the lengtli of this joint and its thickness at the distal end in different 

 individuals. 



As regards the teeth of the fingers in these Catumbella individuals, the following 

 may be remarked : — Each finger is provided wath a cutting-edge, at the end of which 

 stands an obtuse tooth, and between this tooth and the articulation are scan a few other 

 teeth. So, e. g., in a male specimen that is 35 mm. long, the dactylus carries two rounded 

 teeth between the tooth at the end of tlie cutting-edge and the articulation, but on the 

 immobile finger there are here no teeth at all. 



Of another male (No. 20), which is 29 mm. long, one of the equal second legs is 

 represented in fig. 27, and the teeth of its fingers in fig. 28 of PI. 19. The cutting-edge 

 of the dactylus extends along two-thirds of its length, that of the immobile finger 

 is a little longer. The obtuse tooth at the end of the cutting-edge of the dactylus is a 

 little smaller than that of the other finger. Between that tooth and the articulation 

 on the dactylus two obtuse teeth of equal size are seen, as large as the distal tooth ; on 

 the immobile finger, however, three mucli lower teeth, also of equal size, bvit considerably 

 smaller than the tooth at the end of the cutting-edge. 



In the largest female (No. 22), which has a length of 58 mm., the dactylus is armed 

 with four, the immobile finger with two teeth between the obtuse tooth at the end of the 

 cutting-edge and the articulation ; all are smaller than the distal teeth, and those of the 

 dactylus are of somewhat unequal size (PI. 19. fig. 20). In another female, w^hich is 33 mm. 

 long, there are but tW'O small teeth on each finger between the tooth at the end of the 

 cutting-edge and the articulation ; in another, 30 mm. long, three, and in this individual 

 the middle of the three teeth on the dactylus appears double. In both females the 

 cutting-edge of the dactylus is a little shorter than that of the immobile linger. In a 

 fourth young female, 25 mm. long (No. 38), the teeth of the fingers are shown in PI. 19. 

 fig. 29. The obtuse tooth at the end of the cutting-edge is situated on the dactylus at 

 one-third of its length from the articulation, and behind it there exists still only one, 

 situated about twice as far from the articulation as from the distal tooth and of about
