Thank you for your prompt answer concerning the location of the 
booty Tern from which you collected the tick (Oralthodoros copensi6 )» 
I leased on the infonation to Bob fun dell and he recorded it in the 
catalog, etc. 
Lome interesting facts are appearing which I era excited about 
and I think you will be also, -he accompanying map allows the present 
distribution of the two ticks in our area of Interest. Oralthodoros 
caseasls is found throughout the area, but Ixodes lavanen: Is is only 
presently found on four of the leeward Hawaiian Islands. If you 
happen to collect a bird harboring an ,£. , it would mean the bird 
ca.te from one of the four islands. 
Tour chances of finding an Jh 1,. may be low, but certainly the 
next four months will be the best period for them to occur. 
more frequently occurs on the head (around the eyes, in the ears, 
and la the gular area) but may be on other parte of the bod;-*. They 
may get very large ($ inch or more) when engorged. £. £. is quite 
small even when engorged. The finding of either of these species 
on birds at tea will be significant. 
I am working on the distribution of the two species and some 
poeelbl© reasons why i,» i* * 8 restricted to the Hawaiian Islands 
(along with population fluctuations end ecology of the two) for the 
May Report. If you collect any ticks from at sea birds this trip 
please wire Chuck (give host) so he can relay the message to me. 
Send any collections back to D.C. as soon as you return to Honolulu. 
Here's hoping that you will be able to collect some of these during 
the next few months. 
Best regards.
