177. Xenochirus pentacanthus (iilbcrt. 



This species is very generally distribiited from Pugct Sound to Bering Sea. It was never taken 

 aliundantly, but was found at a great many different places, 71 specimens, from l.G to 4.(15 inches long,

 4270. 4278 to 4281. 4283, 4285 to 4289, 4290 to 4293. and 4295.

 together.
