REPORT ON THE PYCNOGONIDA. 91 



there are two females and a male. The male is a great deal smaller than the larger of 

 the two females. I therefore give the description from the larger female. The body 

 is stout, but, as the lateral processes are widely separated, not very robust. The 

 cephalothoracic segment is not very long. Quite in front of it the oculiferous tubercle 

 is inserted so as to overhang the base of the mandiljles. It is much elevated, conical, 

 with two larger eyes directed forwards, and two smaller ones directed backwards. The 

 first and second true thoracic segments together are shorter than the cephalothoracic 

 segment. The last thoracic segment is short, and l^ears at the extremity a very large 

 abdomen, the length of which is nearly equal to that of the proboscis. The abdomen is 

 a little swollen at the tip. Dorsally the surface of the body of the lateral processes and 

 of the aljdomen is furnished with very slender hairs, of which a distinct row is observed 

 on the hinder margin of the diflferent thoracic segments. 



The two mandibles are three-jointed ; the first two joints run parallel to each other. 

 The first joint reaches as far as the end of the proboscis ; the second joint is a little 

 longer ; the third is inserted on the second, with which it makes a right angle. The 

 pincers of the two mandibles are directed horizontally towards each other ; they are placed 

 at a short distance from the end of the proboscis, are straight, and very short. 



The prolwscis is cylincbical, tapering towards the extremity, where the small mouth 

 is situated. At the base of the proboscis the two protuberances representing the palpi 

 are inserted. 



The ovigerous legs are ten-jointed : the first arid third joints are very small ; the 

 second is about twice as long ; the fourth and fifth are the longest of all ; the sixth joint 

 is short ; and of the four last joints the second is the longest and the last the shortest. 

 They are covered with not very long but thin hairs, rows of stronger ones, as a rule, 

 being found at the extremity of the joints. 



The second joint of the legs is nearly twice as long as the first or thiixl, and in the 

 female considerably swollen at the extremity. The fourth joint is also consideral^ly 

 swollen in the female, and is longer than the first three joints together. The fifth 

 joint is much more slender and also a little shorter than the fourth ; the sixth is much 

 longer and, at the same time, a gxeat deal more slender. The two last joints together are 

 not quite one-third the length of the sixth joint. The first tarsal joint is extremely short, 

 the second al^out five times as long. From the first to the sixth all the joints are covered 

 with very long and slender hairs, giving an extremely woolly appearance to the whole 

 animal. The first tarsal joint is furnished with numerous stronger and smaller hairs ; the 

 second shows a row of distinct spines, the last of which is the largest, while the others 

 diminish in size. The claw at the end of the leg is very large ; it is accompanied by two 

 extremely small auxiliary claws. 



The females have very large genital openings ventrally on the swollen extremity of the 

 second joint of all the legs. In the males I could observe the small genital pores only
