Leg I.: femur 0-312 (0-122), trochantin 0-083 (0-122); tibia 0-236 (0-079); 

 tarsus 0-182 (0-049) mm.

Mate7'ial &c. — Of this species I have examined two males and a single female, 

 collected by Dr. Fr. Meinert by sifting at La Moka, in the mouth of August. This 

 species has been previously mentioned from Paraguay and Brazil. 



Remarks. — In minor details, not worth enumerating, my specimens differ from 

 Balzan's description, and also in the very long fingers of the palps in the male, a 

 character not mentioned by Balzan ; as the description of the last-mentioned author 

 is not very complete, I do not find any reason to establish a new species. My 

 specimen (female) differs from Ellingsen's description " in the presence of long hairs 

 on the posterior somites" (cf. 19. p. 12), in the femur, which is of almost equal 

 breadth throughout, and in the hand, which is only a little wider than the tibia and 

 longer than the finger {cf. 19. p. 13). 



The male is easily distinguished from all other species of this group by the peculiar 

 structure of the abdominal tergites. The female is distinguished from Ch. longichelifer 

 Balz. by the less slender femur of the palps as well as by the more elongated shape 

 of the other joints, but especially by the rather long, distinctly clavate hairs.

Cephalothorax. — Eather indistinct ocular spots present. The cephalothorax is 

 much longer than wide behind and gradually attenuated towards the front. The 

 transverse grooves are very deep and prominent ; the deeper posterior one is almost 

 straight, while the anterior is laterally bent outwards and directed forwards. Skin 

 distinctly and coarsely granular everywhere and provided with short distinctly clavate 

 hairs. The second tergite is gradually raised towards its posterior serrated margin. 



Abdomen. — The abdomen is short and clumsy, almost obovate in shape, far from 

 twice as long as broad ; the sclerites increase in length as well as in breadth towards 

 the sixth one. All the tergites are divided by a longitudinal line, which is rather 

 indistinct in the first ones, but becomes more and more prominent behind. The 

 first seven tergites show traces of lateral keels and the first eight have the posterior 

 margin irregularly undulated and serrated. The sclerites are markedly granular all 

 over and bear rather short clavate hairs along the posterior margin in number from 

 10-12; the V.-X. tergites possess in addition to these, six hairs in front of the row, 

 placed within prominent white spots ; the XL tergite has a pair of very long slender 

 " tactile " hairs. 



Sternites without longitudinal line ; the VI.-IX. sternites have a greater or lesser 

 part of the sclerites pale ; this pale area has the anterior margin convex, and possesses 

 in the first-mentioned sternite only a few spines, but in the last two a large number 

 (about 80) of rather long spines standing close together. The last sternite bears two 

 pairs of " tactile " hairs, and the last but one a single pair only.
