Dear Roger* 
I am happy to hear that you have made such headway with the king 
orab report and that we shall see you during the latter part of March, 
alone with your manuscript. 
The use of the name King Crab was recently brought up here by 
Seton Thompson just before he was called by the llaval Reserve (?)* He 
told me that they were checking over the law governing its fishing and 
wanted to be sure they were using. the proper designation* I urged that 
they use the term King Crab in the generic sense to include all Paralithodes 
irrespective of species, inasmuch as we took two species in Alaska; that both 
would be canned; and, so far as we know at present, they would be indis- 
tinguishable when processed* Thus, all King Crabs (P. cants o hfc tica , as 
well as P# platypus ) would 1)6 equally well protected by any law destined to 
safeguard any one of them; this at least until we know more of their specific 
behavior or life histories* 
Then Seton was called; so I took especial pains to soe that the 
Bureau had not failed to get the information I passed on to him* 
It nay well have been Ilopkinson * s report (3rd paragraph of your 
letter) that Seton showed me (or was it some other Bureau report or digest 
of laws?). With reference to the King Crab, I asked him to see to it that 
the name camtschatica f ollowing Paralithodes was deleted in the new draft 
he was working on. 
I do not know who first used the terra King Crab; I believe it was 
Marukawa or some Jap before him. At any rate, his statement, as cited (your 
2nd paragraph), that the King Crab is made up of three species backs up my 
feeling that the term is often used in the comprehensive sense and that it 
should be used that my. If one wants to distinguish between King Crabs 
one can use other or minor designations (adjectives 4r adjectival phrases) 
along with the major term King Crab. For example* 
1. Japanese, Bering Sea, or deep sea King Crab ( Paralithodes oamtsohaticus) ; 
in faot, as you will notioe, Marukawa calls this species ""the Japanese 
King Crab in the title of his report, a fact in a measure based on its 
name cants ohatioa, from the peninsula Kamsohatica, which is now-a-days 
in considerable part Japanese territory.
