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
