and the closely united lateral processes. Legs short with auxiliary claws. Body and 

 legs smooth, furnished only with very small hairs. 

 Description. — 



The cephalothoracic joint is closely connected with the three other thoracic joints ; 

 the lateral processes are short and somewhat triangular, forming in connection with the 

 body a disciform surface, from which the legs radiate in different directions. The 

 proboscis is comparatively large, the form cylindrical, tapering towards the extremity. 

 The oculiferous tubercle, which is small, not very elevated, and furnished with four distinct 

 eyes, is placed dorsally on the middle of that part of the body, which corresponds with 

 the cephalothoracic segment. 



The palpi are small, measuring about two-thirds the length of the proboscis. The 

 first and second joints are very short, the third joint is the longest of all, the fourth again 

 small, the fifth more than twice as long as the fourth, and comparatively slender. The first 

 two joints are smooth, the third joint is furnished up to the outer margin with three long 

 spines, and on its inside with three smaller spines, which are curved ; the ventrally 

 directed surface of the same joint, which contains a large gland, hereafter to be described, 

 has, near the middle, four extremely small spines. The fourth joint is nearly smooth, the 

 fifth is armed with very large and numerous spines near the extremity. 



The first joint of the ovigerous legs is very small, the second and the third are a little 

 longer, the fourth and the fifth are the longest, the sixth is short again, the seventh, 

 eighth, ninth, and tenth are about the same length, and gradually diminish slightly in 

 breadth. The first five joints are nearly smooth, towards the distal extremity the sixth 

 shows some short and not very strong spines, whereas the four following joints are 

 furnished in the same place with much stronger and slightly curved spines. Towards 

 the end of the tenth joint there are a considerable number of these spines, while a claw 

 and true denticulate spines are totally wanting. 



The first three joints of the legs are small ; of the three following, the middle joint is 

 the longest. The first tarsal joint is extremely short, the second comparatively long, and 

 very slender in comparison with the other joints of the legs. The claw is about one- 

 third the length of the second tarsal joint. The auxiliary claws are comparatively 

 long, two-thirds the length of the claw. The hairs on the different joints of the legs are 

 small ; the distal extremity of these joints is, as a rule, furnished with a row of longer 

 and stronger spines, especially at the end of the sixth joint. The first tarsal joint has
