This small species has a fairly well-built body, with the lateral processes rather 

 widely separated, and as long as the diameter of the trunk. The trunk articulations 

 are very distinct, and immediately behind the lateral processes. No setae of any kind 

 are to be seen on the body. 



The Cephalon is stout but not widely expanded, showing two distinct lobes for the 

 reception of the chelifori ; it is not quite as long as the second and third trunk 

 segments together. 



The Ocular tubercle is very stout, of small elevation, rounded at the summit, and 

 carries four well-developed eyes. It lies just in front of the first pair of lateral 

 processes and behind the neck. 



The Abdomen is of moderate dimensions, curved upwards, and not separated by 

 an articulation from the trunk. 



The length of the body is 2"75mm., and its extreme width r5mm. 



The Proboscis arises on the ventral side of the trunk, and measured ventrally it 

 is nearly one-third the length of the entire body. It is stout, gently tapering to a 

 rounded extremity, quite smooth. 



The Chelifori are well developed; the scape is single-jointed, extending beyond 

 the proboscis ; provided laterally with comparatively long setae. The chela is not very 

 long, the palm and fingers occupying approximately equal halves ; the former is 

 covered with setae, and the fingers, rather curved, are supplied with a very moderate 

 number of slender teeth rather widely separated. 



The Palp is five-jointed, and rises underneath the chelifori (fig. 3a) ; as usual, the 

 first joint is very small and the second long. Owing to distortion in mounting this 

 appendage, the comparative length of the second and third joints cannot be very 

 accurately stated, but the second appears to be twice the length of the third ; the 

 fourth is half the length of the third, and the fifth is longer than the preceding, the 

 proportions being 5 : 2"5 : r25 : 1'75. The terminal joint is ovoid, and fairly well 

 supplied with comparatively long setae ; the three preceding joints have well-developed 

 distal fringes and a small number of setae scattered along the shaft ; these are most 

 numerous on the third joint. 



The Oviger is ten-jointed, and rises from a small process of the trunk, visible 

 dorsally, just in front of the first pair of lateral processes (fig. 3 b). The first three 

 joints are very small ; the second and third are subequal in length, the latter much 

 the more slender ; the fourth is longer than the three preceding ones together ; the 

 fifth is twice as long, much curved, and bears a few setae on its outer margin ; the 

 sixth is half as long as the fourth. The four terminal joints are very small, the first 

 being the largest, and all bear two or three long setae distally. The terminal claw is 

 long and slender, with five slender teeth set at irregular intervals. Of denticulate 

 spines, such as characterise the genus Nymphon, there are none, but of special spines 

 there are 2:2:2:1 on the four joints ; these are curved blades without any other 

 distinguishing feature.
