CRUSTACEA. 



Length, six to eight lines. There is a resemblance in this species 

 to the fiwgiensis; yet it is much larger and lighter-coloured. The 

 shorter branch of the stylets is not slender linear, as in the fuegknsis, 

 and has three setae at apex ; the front is much less projecting. The 

 granules of the surface are quite small, and there is some pubescence.

Island of Maui, Hawaiian Islands. 



The basal part of the last abdominal segment is very short, or 

 transverse linear, and the rest of the segment is narrow and quite 

 prominent ; the longer branch of the caudal stylets projects beyond 

 the abdomen, two-thirds the length of the abdomen or more. The 

 articulations of the thorax are but slightly arcuated, excepting the 

 two posterior, and these are not very much so. The antennae of the 

 specimen were mutilated.
