PUGET SOUND CRUSTACEA. 265 



above is placed considerably in front of the eyes, while the ex- 

 ternal flagellum of the antennules falls short of the broken tip 

 of the rostrum. As was the case with Stimpson's specimens, 

 no epipod could be discovered on the third maxillipeds.

Our specimens differ from Stimpson's diagnosis in the fact 

 that the third maxillipeds are slightly longer, reaching a little 

 beyond the extremity of the antennal peduncle to nearly the 

 middle of the rostrum. Some of the smaller specimens show 

 a minute pterygostomial spine, and in this respect resemble the 

 allied H. caintscliatica Stimpson. (Proc. Acad. Nat. Sci. Phil., 

 i860. 33.)

Two specimens ( ^ and 9 ) agree very well with British ex- 

 amples of this somewhat variable species which has not hitherto 

 been recorded from the Pacific.
