460 Mr. T. V. Hodgson on a new Pycnogonid 



The above cliaracters arc probably quite sufficient for 

 identification, and a more detailed description may now be 

 given. 



The body, including the probosci.*, is quite smooth and 

 averages between 7 and 10 millimetres in length. Anteriorly 

 it is curved downwards so that the proboscis is inclined at a 

 moderate angle. It is slender, and the lateral processes are 

 long, the segmentation being distinct and immediately behind 

 them. The ocular peduncle is short and is situated just in 

 front of the first pair c£ lateral processes. Four eyes can be 

 distinguished, but the state of their development is a variable 

 feature. 



The abdomen is small, ovoid, and directed obliquely 

 upwards. 



The proboscis is perfectly smooth, cylindrical, with a very 

 slight swelling along the middle of its length ; the extremity 

 is rounded. 



The mandibles arise above and slightly in front of the 

 proboscis on an enlargement of tlie cephalon, which is here 

 rather more than twice its diameter posteriorly. A distinct 

 projection of the cephalon forms a base for these appendages, 

 which are 2-jointed. The scape is longer than the chela 

 and it is also longer than the proboscis. It is smooth, there 

 being only a very few setaj scattered along its length and a 

 whorl of them at its distal extremity. The chela is rather 

 smaller than the scape, with fine setse scattered all over the 

 proximal half. The fingers occupy nearly half the length of 

 the joint; they are slender and much curved near the tip so 

 as to cross when closed. The inner border of both fingers 

 is furnished with a row of fairly stout teeth of nearly 

 uniform size. 



The palps arise below and somewhat behind the mandibles, 

 more strictly at the side and base of the proboscis. They 

 are 5 -jointed, the second joint being considerably the longest, 

 the fourth is half the lengtii of the third, and the fifth is 

 longer than the fourth. The first joint is very small and 

 devoid of setae; the second, with the succeeding one, bears a 

 few set£e sparsely distributed along its entire length, the 

 setse being most plentiful at the distal extremity, where they 

 form an imperfect whorl round the joint. The fourth joint 

 is half the length of the third and is more abundantly 

 supplied with setse especially about the outer side, a few 

 being scattered elsewhere. The fifth joint is longer than 

 the preceding, rounded at the distal extremity, and more 

 richly supplied with setaj : these are stouter than on the 

 other joints, but have cssentiallj^ the same arrangement ;
