408 ON THE STOMATOPODA AXD MACRURA BROUGHT BY 



Tail-fin. The exopodite of the iiropod is longer than the endopodite. This, in 

 turn, is longer than the telson. 



Length of largest specimen 7 mm. 



Four specimens of this species were found living among the spines on the back 

 of a black starfish of the genus Linckia.

Carapace. The rostrum reaches the end of the first joint of the antennular stalk, 

 is strongly curved downwards, and bears no teeth. The antennal spine alone is present, 

 and the pterygostomial angle is rounded. 



Antennae. The stalk of the first antenna does not quite reach the end of the 

 scale of the second. The flagella are subequal and of moderate length onl}'. The 

 stalk of the second antenna is as long as the basal joint of the first, and the scale 

 is broad. 



Mouth-limbs. These have not been examined in the single specimen. The third 

 maxilliped reaches half way up the last joint of the second antennal stalk. 



Legs. The first pair of legs outreach the antennal scale by the last half of the 

 wrist and the hand. The second pair are equal, symmetrical, and without spines on 

 any of their joints. The hand is long and rather narrow. The wrist is half the 

 length of the palm. The fingers are unequal, the movable one being considerably 

 longer than the immovable and hooked at the end. The immovable finger is more 

 than half as long as the palm. 



Tail-fin. The exopodite of the uropod is slightly longer than the endopodite. 

 The latter is somewhat longer than the telson, which is triangular, with a rounded 

 apex bearing the usual six spines. 



Length .50 mm. 



One ? fi'om a Tridacna, in Tubetube, Engineer Group, British New Guinea.
