-Periclimenes investigatoris, 



and is less than 4« times as long as wide. 1 There are no spines 

 on either merus or carpus. The carpus is conical, more than r/5 

 times as long as wide. The palm is 3 times as long as broad and 



the fingers are about two- 

 thirds its length. The 

 fingers (text-fig. 27a) have 

 large apical claws which 

 cross one another when 

 the claw is shut. The 

 cutting edge of the fixed 

 finger bears a series of 

 small teeth in the proxi- 

 mal half of its length and 

 there is one rather larger 

 tooth in the basal third of 

 the dactylus. The smaller 

 limb of the* same pair is 

 similar, but the carpus is 

 twice as long as wide and 

 the fingers almost as long 

 as the palm and without 

 teeth. 



The last three pairs of 

 peraeopods are rather 

 stout ; those of the third 

 pair scarcely reach the tip 

 * of the scale. The propo- 



dus bears setae on its posterior margin ; in the third and fourth 

 pairs it is about 4*5 times the length of the dactylus and in 

 the fifth pair about 6 times. The dactylus (text fig. 2jb) is curved, 

 rather slender and with a small accessory tooth. 



The sixth abdominal somite is fully one and a half times 

 the length of the fifth. The telson bears the usual two pairs of 

 dorsal spinules, the first a little in advance of the middle, the second 

 nearer to the first than to the apex. The external margin of the 

 uropod is ciliated. 



The above description is based on a single ovigerous female 

 15 mm. in length. 



P. investigatoris is easily distinguished from any other species 

 in the same subgenus by the great length of the spine forming 

 the lateral process of the antennule.
