284 CALMAN. 



APPENDIX. 



Since the above paper was written I have received from Mr. 

 N. R. Harrington a few Crustacea which had been overlooked 

 in sorting out the Puget Sound material. Among them is a 

 specimen of a small Slerocrangoii closely resembling but 

 apparently distinct from 5. miiriciis (Dana). I believe it to 

 be identical with a species to be described by Mr. A. O. Walker 

 in a forthcoming paper in the Proc. Biol. Soc. Liverpool, and 

 of which Mr. Walker has been good enough to send me a 

 sketch. His specimens were dredged in Puget Sound by Pro- 

 fessor Herdman, of Liverpool. 



The collection sent me also includes a second specimen of 

 Sylon, attached to a Hippolyte brevirostris Dana.
