large ovoid eyes, the anterior pair are close together. Above the eyes the tubercle is truncated to terminate 

 in a short spine. The abdomen is rather long, directed upwards, and bears about its middle two branched 

 spines and a few setae more distally. In the mid dorsal line are three long slender branched spines ot 

 some considerable elevation. The length of the entire body is i mm and its breadth is 0,5 mm. 

 The proboscis is small, ventral, directed downwards, forming a rounded cone. 



The cheliferi are well developed , the scape is single-jointed , short with a strongly developed 

 branched spine about its middle and others distally. The chela are fairly well developed turned vertically 

 downwards, the dactyli about as long as_ the spinous palm, and curved like a pair of callipers, without teeth. 

 The palps are not perfectly developed and it is difficult to say how many joints there should be. 

 It was injured in removal for detailed examination, but in its present condition it consists of a short Joint 

 with a couple of minute seta distally, then follows a longer Joint and the remainder of the appendage is 

 bent to a considerable angle to the preceding portion. At the bend there is a small Joint quite triangulär 



in shape and carrying on its outer margin a spinous setae. 

 The rest of the limb is not divided up into joints but if the 

 arrangement of the setae may be taken as a guide there 

 should be three. The proximal third is stout, dorsally and 

 distally it bears two long spinous setae. The middle third is 

 much more slender and devoid of setae, while the distal 

 third is slightly tapering, with a long spinous seta at its base 

 and half a dozen at the distal extremity. 

 Ovigers none. 



Legs are not long, but armed throughout with spines 

 which are for the most part branched, these are most 

 numerous as well as best developed on the second tibia 

 and arranged dorso-laterally. A few setae occur ventrally. 

 Of the three coxae the second is a little the longest, the spines being comparatively small and few. The 

 three following joints progressively increase in length to a slight extent, the tarsus is very small, and has 

 a few spinous setae ventrally, the propodus is slightly curved more than half as long as the second tibia, 

 it carries one stout spine ventrally and proximally four or five smaller ones, more distally a few setae 

 occur dorsally and there are no auxiliaries to the stout terminal claw. 



The second tibia of the first leg has a very large pair of branched spines dorso-laterally about the 

 middle of its length, another pair, smaller between this central pair and each extremity, there are not less 

 than two pairs of smaller spines and a few scattered ones complete the series. 



The first tibia has its principal branched spines about its middle and at the distal extremity. 

 The posterior pair of legs are not so fully developed as the others, being about three quarters of 

 their length. 



The branched spines so characteristic of this species are really dermal prolongations which support 

 one or more stout setae which are usually implanted in a socket. 



The two specimens are both immature, one much more so than the other ; in fact this last is still in 

 a post-larval condition, the posterior pair of legs is represented only by a Single Joint, which is however 

 comparatively long, and ends with a small but stout claw. It may seem dangerous to establish a new species 

 on such material. The spinöse nature of the animal seems however sufficiently characteristic to justify such 

 a course.
