 together, neck slender and elongate. Proboscis swollen centrally and constricted behind mouth. 

 Eye-eminence with low conical apex. Chelifori elongate; scape nearly as long as proboscis; hand 

 rather longer than scape, with slender, tapering, evenly curved fingers. Palp half as long as 

 body; relative length of its segments as 2:8:9:10:6. False leg as long as body; relative 

 length of its segments as 2 : 4 : 4 : 20 : 24 : 10 : 6 : 4 : 4 : 3; denticulate spines with a short sharp 

 basal point, and six to eight sinuous serrations on each side. Legs slender and elongate, spines

 principal claw slender, slightly longer than tarsus ; auxiliary claws four-fifths as long as principal 

 claw. Abdomen very elongate, slender and club-shaped; as long as the first two thoracic segments

„The length of the body is about four and a half times its greatest breadth; the lateral 

 processes are separated from one another by distinct intervals, and are about as long as the 

 body is broad; the neck is half the length of the rest of the body and much narrower. The 

 divisions between the segments are well marked. The proboscis is rather longer than the neck, 

 and is dilated at the base where it is considerably broader than the body ; distally it narrows 

 slightly and ends in a rounded extremity. The abdomen is about a fifth of the length of the 

 body, deeply notched behind. The first pair of appendages are very large, their basal joint is 

 as long as the proboscis, stout, rather thicker distally than proximally. The second joint is also 

 very long, though shorter than the first, it is ovoid and swollen ; the finger into which it is 

 prolonged is about half the length of the rest of the joint, is provided with a series of denticles 

 and ends in an extremely fine, curved point; the movable finger resembles the immobile one. 

 The second jjair of appendages are of the same length as the first, but very slender; the first 

 joint is very short, the second is cight times as long, the third is a little shorter than the 

 second; the fourth is a little more than a tliird of the length of the third. The third pair of 

 appendages are long and slender; the first joint is short, the .second longer, the third twice as 

 long as the second, and rather dilated distally; the fourth longer and more slender than the 

 third, gently curved; the fifth short; the .sixth longer than the fifth, about a third of the length 

 of the fourth; the seventh and eighth, ninth and tenth, nearly equal in length; the number of 

 spines on the tenth joint is over fourteen, but the api)endage is damaged on both sides and
