I have finally gotten bade in harness and, first of all, I 
want -bo thank you for your good letter of November 4th, in which you 
so promptly identified tbpse flat worms from the king crabs for me, 
1 6' ■ ; 5 i - ' j • r • 
1 must confess that most of our time was spent at sea and 
that most of ay pictures are distant views of sixer® linos. However, 
v/e did some shore collecting, but the flat worms wore not ranch in 
evidence, he sorted over our hauls quite carefully and did poke in and 
around the rocks to a considerable extent. The collections have just 
recently arrived and there will be quite a lot of sorting to accomplish 
with what vre got. It is possible that some other things will turn up. 
With reference to the barnacles, ve always found the flat 
worms in empty barnacle shells on the crab’s back, and so your sur- 
mise that they are really associated with the barnacles is correct. 
The color of those flat worms, as I recall it (and I am 
looking at that ancient 1886 edition of Ridgway) was somewhere be- 
tween the lighter parts of smoke grey and drab grey in the upper right 
hand comer of Plate 2. I’ll try to get you some color notes, if only 
by comparison with a Sears Roebuck paint ohart, which you find in al- 
most every household in Alaska. 
I just couldn’t make Philadelphia, I reached home just two 
days before Christmas and there was too much to attend to both there 
and at the office to permit me to get away, I certainly regret that 
I was not able to talk things over with you and Dr, Stirewalt, You 
have the right slant on the wholes matter, but, nevertheless, if on© 
cannot give the time or hasn’t the material to make a proper revision 
of a group, a check list embodying all the names in literature is a 
very useful thing if it 1® carefully done and all th© references are 
carefully oheoked and are reliable. Perhaps th© key that they have 
planned to accompany the check list is a bit premature, but, other 
than th© key, the list of reference® and names has such to reoomnend
